The Yellow Group observed the binary star system Omicron 1 Cygni on July 17, 2015 from the Lewis Center for Educational Research. They measured the drift time, separation, and position angle of the two stars 10 times each and found average values of 57.5 seconds, 340.9 arcseconds, and 324.05 degrees respectively. When they compared their measurements to historical observations from 1800 and 2008, they found small differences less than 3 arcseconds and 1 degree, indicating their results matched previously collected data well.
The Evolving Relation between Star Formation Rates and Stellar Mass Russell Johnston
Quantifying the interplay between star formation and stellar mass is a crucial component to understanding the build up of galaxies over cosmic time. There have been many investigations of this relationship, using both observations and simulations, with the aim of shedding light on how it connects with the underlying physical processes governing galaxy evolution.
In this talk I will present recent work where we have examined the star formation rate (SFR) - stellar mass (M∗) relation of star-forming galaxies in the XMM-LSS field to z ∼ 3.0 using the near-infrared data from the VISTA Deep Extragalactic Observations (VIDEO) survey. Combining VIDEO with broad-band photometry, we have used the SED fitting algorithm CIGALE to derive SFRs and M∗ and have adapted it to account for the full photometric redshift PDF uncertainty.
We have also compared our results to a range of simulations where I will show that the analytical scaling relation approaches, that invoke an equilibrium model, a good fit to our data. Within a simplified framework, such a model does not include the modelling of e.g. halos, cooling, or galaxy mergers, suggesting that a continual smooth accretion regulated by continual outflows may be a key driver in the overall growth of SFGs.

Observations of
Omicron 1 Cygni
(SFTA 50AD)
2. Overview
● Omicron 1 Cygni has only been measured 35 times since it was
discovered in 1800, averaging about one measurement every 6
years, and it was last observed in 2008, which we are thinking
might have been an outlier data point due to our data matching
to the 1800 measurements more than the 2008 data.
● Omicron 1 Cygni consists of Omicron 1 and 30 Cygni, an
orange super giant and blue-white star, respectively and is in
the Cygnus (Swan) constellation.
● With an average drift time of 57.51 seconds, we found the
separation to be 340.9 arcseconds, and the position angle to be
324.05 degrees.
