Works and Days



Astronomy at the University of Michigan: Sarah Racz, Winter Shadow 2016

The first thing I did when I found out I was accepted for the Winter Shadow program in Astronomy at the University of Michigan Ann Arbor was look into getting a parka. I was excited to visit Ann Arbor for the first time, and really hoping for some snow.

I stayed in Ann Arbor for a week, and left with unending love for what has become my favorite diner of all time.

I worked with a Mario Mateo, who is an astronomer at the University of Michigan. The project I worked on sought to measure the dependence of the magnitudes of RR Lyrae stars upon metal abundance. RR Lyrae stars are variable stars, known for having short periods. All the stars we observed were from the globular cluster Omega Centauri, which is a cluster known for having a range in the metallicities of its stars. All the data was from a telescope in La Serena, Chile that Mario had built. During the week I wrote several scripts in Python to read from huge files of data and run data analysis.
