The Australian 50 Hour Project Nova Aquilae - The Vulcan Star by Alexander Hons

  1. 1. The Australian 50/50 Nova Aquilae – The Vulcan Star Alex Hons Mary McGrath Dr Graeme White David Platz
  2. 2. Where is the Nova Aquilae? Where is Irvinebank in North Queensland?
  3. 3. The Purpose of this Talk. • Give recognition to Dr McFarlane. • Acknowledge the history and promote Irvinebank and it peoples. • Talk about the LCO/GHOU 50 Hour/50 Nations Science Education project. • Acknowledge the discovery of the Vulcan Star and place a respect plate on the grave of Dr McFarlane. . Acknowledge the TSAA (School of Astronomy and Astrophysics at Atherton State High School North Queensland) and OCAS (Online College of Advanced STEM). • Special thanks to the Beatties for access to the observatory house for our research.
  4. 4. The Vulcan Mine - Irvinebank
  5. 5. • Tin lode discovered in September 1888 by Italian woodcutters and miners - Harry Maranta, Alexander Leone, Battista Leone and Giuseppe Lampatta. • 1889 assayed 20% tin. • Syndicate of local miners purchased the Vulcan mine from the Italians for £2,100. • This company was the first joint stock company on the Walsh and Tinaroo fields to pay a dividend, in January 1891. • Moffat infiltrated the Vulcan company through nominees and within seven months he controlled 40% of the
  6. 6. • A third company, the Vulcan Tin Mining Company was formed in 1892. Its capital was increased to £44,000. • Moffat continued technical innovation installing in 1893 a first motion double action winding engine, the first on the Walsh and Tinaroo field. • Conbert Cornish boiler powered the 16-horsepower Tangye winding engines with 4 ft 7 in drums with two 5 ft 11 in pully wheels at the base of a 30 ft timber headframe. There were two cages for miners to descend the 302 ft shaft. • Over the next 15 years the Vulcan yielded 9,000 tons of black tin worth £377,362 and paid dividends totalling £162,030.
  7. 7. • The 1907 and 1908 strikes affected the value of Vulcan ore. • Due to Moffat the Vulcan company continued. Stannary Hills company forced to closed the Rocky Bluff battery after 1909 and railed its ore to Irvinebank. • In 1913 an aerial tramway installed from the mine to the Loudoun mill. • Improved travelling to the working faces installed in 1915 when the mine was down 1,460 ft.
  8. 8. Pictures of Vulcan Mine
  9. 9. Fresh chimney stacks in 1921. The mine and machinery foundations are situated on a narrow bench excavated into a steep hillside at the head of a gully running down to Gibbs Creek.
  10. 10. There were major strikes in the Vulcan in 1907 which were importance in the history Of the Labor movement. The mine is associated with miners William McCormack and Edward Theodore (Queensland Premier and Queensland and Australian Treasurer) and the establishment of the Australian Workers Union (AWU).
  11. 11. Who are these kids? I hope they were not fodder for the trenches of WWII
  12. 12. North Broken Hill Limited applied for 60ha lease over the Vulcan workings in 1947. In 1981 Don Walker of Herberton purchased the mine as a local tourist site.
  13. 13. • Today, the Vulcan mine and its headframe is significant in Queensland's history for its development as a local shareholders mine which supplied ore to the main battery, the Loudoun mill, in Irvinebank. • It was the most productive tin mine in North Queensland. • It is Australia's deepest tin mine (at 464 metres) and has one of the largest headframes still remaining. • A rare, uncommon or endangered aspect of Queensland's cultural heritage. • This steel headframe is one of very few dating from before World War I and still standing on its original site. • A beehive brick covered underground water tank above the mine is now rare in the North Queensland context.
  14. 14. The local museum in Loudoun House, originally John Moffat’s own home, contains much information about the beloved doctor who is given as much prominent space as Moffat himself.
  15. 15. Dr William McFarlane
  16. 16. Dr William McFarlane -- A man of Sterling Worth. Born at Chepenehe, Lifou April 5 1866 Ordained at Cheshunt College May 29 1891 Posted by London Missionary Society to Tatzukuo, Inner Mongolia 1892-1894 Graduated from Edinburgh University as a Doctor of Medicine 1900 Served in practise with Dr Beresford in Chertsey, the Wirral Children's Hospital and the Mafeking Refugee Camp.
  17. 17. He had "A colourful and adventurous life growing up in the South Pacific and the Torres Strait and later as a missionary in the South Pacific and Inner Mongolia." Took Charge of the Walsh District Hospital at Irvinebank in 1906." The hospital was on the hill where Vulcan Ore Rd leads to today. The building no longer exists. He had served at the Irvinebank hospital for 13 years. “Dr. W. E. McFarlaue was re-appointed Medical Officer at the … salary of £400 per annum”. In 1907 he made astronomical observations with a 7.6-cm telescope from the roof of the hospital. Built an observatory to house a 17.8 cm Cooke Refracting telescope in 1917. 06/08/1918- observed Nova Aquila, brightest nova since Kepler's nova of 1604 which MacFarlane named the 'Vulcan Star'. It is still known locally by this name. Elected Member of Royal Geographical Society & Member of Royal Astronomical Society Died 20 August 1919 from a severe attack of influenza (?) age 53. He left no relatives in Australia.

  22. 22. Dr McFarlane’s Death - Dr McFarlane is dead. Irvinebank and Stannary Hills, with the assistance of Dr. McFarlane, had for several weeks been battling with a severe attack of influenza, which was aided by the worst of weathers. For the past week or thereabouts, the weather has been of the brightest, and the epidemic appeared to have been bested. Everyone was congratulating themselves upon having had a man of Dr. McFarlane's worth amongst them during the battle. The doctor himself was speaking of a well-earned holiday, a trip to India, as a reward and rest after this struggle.
  23. 23. Impressive Funeral - Irvinebank, Aug 18. 1919 The funeral was by far the largest and most impressive ever seen in Irvinebank. The cortege was of considerable distance, and the remains were followed to their last resting place by practically the entire population of the town, while residents came from Stannary Hills and other centres to pay their last tribute to the doctor's memory. Sorrow at his death was widespread and heartfelt. The coffin was hung with wreaths sent by those who had known him and revered him in life, and who mourned the death of a physician who gave his life in the service of suffering humanity. To the children he was a patron, consoler and fairy godfather. When they needed a football, sets of cricket tools, or other implements of outdoor sport, it was to the doctor they went with their requests, which were never once turned down. They marched in a sorrowing group fully 200 strong, and were given pride of place next the hearse, as he would have wished. Stepping behind them were men

  33. 33. Riverview Observatory
  34. 34. Riverview College - Saint Ignatius' Riverview Observatory Jesuit astronomer and seismologist Edward Francis Pigot (1858-1929) established the Riverview College Observatory at the prestigious school in 1909. Pigot transferred to the school from Shanghai in 1907, the same year McFarlane arrived in Irvinebank. Pigot wanted to add an astrophysical section to the observatory, but only if he could obtain first-class equipment.
  35. 35. Riverview College - Saint Ignatius' Riverview Observatory Cost was 160 pounds and money was donated by the father of a former Riverview who was killed in France in 1916. Pigot raised the considerable sum and then arranged for its dismantling, packing and freighting from Irvinebank to Sydney. Herberton firm Jack and Newell, founded by two early associates of John Moffat, carried out these operations, which involved transport via dray, rail and ship. The firm had previously transported the telescope from Melbourne to Irvinebank in 1910. Nine months after the purchase, the telescope reached Sydney on August 21, 1922.

  38. 38. In 1921 the telescope was up for sale. It was bought by St Ignatius College in Sydney for the observatory Father Edward Francis Pigot was setting up in the school grounds. William McFarlane’s 7 inch Cooke refractor telescope remains in usable condition at St Ignatius’ College, Riverview on Sydney’s Lower North Shore.
  39. 39. Vulcan Star – Nova Aquilae – V603
  40. 40. Vulcan Star – Nova Aquilae – V603 Dr McFarlane named the exploding star Vulcan Star after John Moffat’s famous tin mine. “Although it was just about visible to the naked eye the previous night, on the night of June 8-9, 1918,” it outshone every other star but two, an instant astronomical sensation”. “At the time, the life and death of stars was not well understood and there was as much bafflement as excitement amongst astronomers as the news spread and all telescopes were trained on it,” Ms Davis writes.
  41. 41. The Vulcan Star • V603 Aquilae (or Nova Aquilae 1918) was a bright nova in the constellation Aquila in 1918. • A binary system, comprising a white dwarf of about 1.2 times as massive as the sun and donor low-mass star about 20% of the Sun's mass, in a close orbit of approximately 3 hours 20 minutes.

  52. 52. What is a Nova?
  53. 53. What is a Nova? • A nova is a transient astronomical event that causes the sudden appearance of a bright, apparently "new" star, that slowly fades over several weeks or months. • Novae is an interaction between two stars that cause the flareup that is perceived as a new entity. • The Milky Way experiences about 50 per year. But only 10 per year are discovered. • Either a pair of red dwarfs or a white dwarf and another star.
  54. 54. • The white dwarf captures matter from the companion. Runaway nuvlear fusion occurs when the temperature reaches ~20 million K initiating nuclear burning. • The rise to peak brightness may be very rapid, or gradual. • Fast novae fade in < 25 days. Slow novae take more than 80 days. • Amount of material ejected is about ​1⁄10,000 of a solar mass. • Ejecta velocities as high as several thousand kilometers per second. Contains Helium, Carbon, Nitrogen, Oxygen, Neon, and Magnesium.
  55. 55. Dr McFarlane Remembered
  56. 56. Dr McFarlane Remembered • He is remembered by • David Platz, Head Teacher, School of Astronomy and Astrophysics, Atherton. • Dr Graeme White, Astronomer, Wagga Wagga. … and others. 2018 is the centenary of William McFarlane’s discovery of the Vulcan Star in the night skies on June 8, 1918. Atherton State High School’s motto, “Alis aquilae” (“On the wings of an eagle”). We know that McFarlane’s seemingly damaged gravestone was deliberately made that way — the symbol of a broken life.
