  • Techniques of measurements What is parallax? D pc  1 parcsec
  • Techniques of measurements • Basics of Parallax : • Arc (S ) = radii (r) x angle (p) • • • • r r r r …{ angle is physically measured, Arc is dist bet S & E, radii is dist bet Earth & star } = S/p x 360/2 x pi (degrees) ... { 1 deg = 3600 sec} = 206265 x S/p … { p is in arcsec} = 206265 AU / p (arcsec) = 1 parsec = 206265 x 15,00,00,000 kms = r / 9.46 x 1012 Ly = 3.26 Ly • Distance in parsec Dpc = 1/p (arc sec) • 1pc = 3.26ly = 206265 A.U. • For stars having co-latitude  : Measured change = True change / cos  β • Parallax method is reliable up to about 1kpc
  • Magnitude, Scales & Calculations • Magnitude scale – Originally by Hipparchus : – After the sunset the first set of stars to be seen were 1st magnitude stars, then 2nd, 3rd, … magnitude stars are visible. – Hence the brightest stars are 1st magnitude while the faintest stars are 6th magnitude stars. • When quantitative studies was done with the visual appearance and the amount of light received from the stars it was observed that the magnitudes are logarithmically related to the flux of light emitted by the stars. Santosh Takale (santoshatbarc@gmail.com 9967584554)
  • Magnitude, Scales & Calculations • The flux l is defined as the amount of energy received per unit area per unit time. e.g. we receive solar flux of 1400 W/m2. • The flux received is inversely proportional to the square of the distance. • If the two stars emit flux l1 and l2, then their magnitudes m1 and m2 respectively are related by the formula: m2 – m1 = - 2.5 log(l2/l1) • The 6th magnitude star is 100 times fainter than the 1st magnitude star. Santosh Takale (santoshatbarc@gmail.com 9967584554)
  • Magnitude, Scales & Calculations What’s Ref : • A survey of hundred 6th magnitude (visually the faintest) stars around the pole star was done. The average flux of these 100 ‘north polar sequence’ stars was taken as the flux for the 6th magnitude star. • From that, for m = 0, the flux is 2.48 x 10–8 W/m2 • Once the fixed point of magnitude scale was defined this way, the brightest star have magnitude even negative. E.g. the Sirius has magnitude of –1.47, Venus can have magnitude of – 4.4 Santosh Takale (santoshatbarc@gmail.com 9967584554)
  • Magnitude, Scales & Calculations Magnitude scale : Santosh Takale (santoshatbarc@gmail.com 9967584554)
  • Magnitude, Scales & Calculations Apparent/Visual and Absolute magnitudes • In order to compare the real brightness of stars, one uses absolute magnitude (M) - It is the apparent magnitude of an object when it is placed at a distance of 10pc. • The sun’s apparent magnitude is – 26.8, while its absolute magnitude is 4.5 • A star might look brighter than another star – Either, it is actually brighter – Or, it is closer to us than the other star
  • Magnitude, Scales & Calculations Relation between m and M : • M = m – 5 log Dpc + 5 • Canopus (the second brightest star in the night sky) has apparent magnitude of -0.72, while the absolute magnitude is -2.5 • Estimate its distance. • Sirius has m = - 1.46 and M = 1.41 • Estimate the distance of Sirius. Santosh Takale (santoshatbarc@gmail.com 9967584554)
  • Distance Estimation using HR diagram • Knowing the spectral class of stars one can determine its absolute magnitude • Knowing the apparent magnitude we can determine its distance • All O class stars have same brightness. Hence by finding O type star in distant cluster – one can determine cluster distance
  • Sun – A perfectly black body!
  • Wien’s displacement Law • maxT = 0.29 cm-K • Larger the surface temperature, the star peaks at smaller wavelength
  • Colour Index • Magnitude gives only information about the flux, while the colour index gives information about the colour of the star, which might be useful to know the structure of the star/ its position in HR diagram. • To find the colour index, typically three different filters are used. U, B, V • B: Blue filter has central wavelength of 440nm • V: Visual filter has central wavelength of 568nm Santosh Takale (santoshatbarc@gmail.com 9967584554)
  • • The apparent magnitudes using these filters are found. • Then B-V colour index is calculated. – For bluish star, magnitude using B filter is smaller than that using V filter. Hence B-V number is negative. – Similarly B-V number positive means the stars are reddish in colour. – E.g. Betelguese has colour index B–V = 1.50 while Rigel has colour index = –0.03 Santosh Takale (santoshatbarc@gmail.com 9967584554)
  • Standard Candles : • If we had standard light bulbs around the universe, we could have found distance from the source by measuring the intensity of light from that source alone. • Such sources are called “standard candles”. • They are: – Cepheid Variables – Supernovae
  • Variable Stars • Some stars are found to have variable magnitudes. • Their magnitudes increase and decrease over the period. • The first such star was observed in 1596 by Fabricius. – It was o-Ceti or Mira. – Its period is 11 months (332 days) – Its magnitude varies between 3.5 to 9 • In 1784,  Cephei, a yellow supergiant star was found to be variable : Its period is 5d 8h 37m
  • Cepheid Variables • Stars having similar light variation as  Cephei are called Cepheid variables. • Cepheid variables are supergiant stars and can be seen at distances out to about 10-20 Mpc.  American astronomer Henrietta Leavitt looked at many Cepheid variables in SMC.  She found the period luminosity relation (reported in 1912). • One needs a distance measurement from some other method for at least one Cepheid – parallax for delta Cephei or distance to SMC.
  • Period – Luminosity relation Santosh Takale (santoshatbarc@gmail.com 9967584554)
  • Types of spectra • Hot solid bodies show continuous spectra • Atomic gases show line spectra
  • Supernovae • Constant absolute magnitude of -19.6 • Type I – no hydrogen line in spectrum, shows Si emission • From white dwarfs or stars close to the Chandrasekhar limit • Very bright initially, and slow decay in brightness due to cobalt  iron conversion • Brightness estimated, standard candle. hence
  • Doppler Effect • Approaching vehicle’s whistle blows with higher pitch. • The receding vehicle’s whistle has lower pitch. • The frequency of the whistle is the same. • We hear different notes because of the motion.
  • Determining Stellar distance from Doppler Shift • Comparing wavelengths of the absorption lines of stars with those in the laboratory frame, we can find whether the star is approaching us or receding from us. • Entire pattern needs to be compared for this.
  • Hubble’s Law vH D v  recessiona l velocity H  Hubble Constant (73 km/s/Mpc) D  Distance • Edwin Hubble in 30’s found that all the far off galaxies show red shift indicating that they all are receding away from us. • Farther the galaxy, they recede faster.
