Gregory A. Feiden

Assistant Professor of Astronomy
University of North Georgia


Hello and welcome! I am an Assistant Professor of Astronomy and Observatory Director at the University of North Georgia in Dahlonega, Georgia, USA. My research is focused on the structure and evolution of low-mass stars, where low mass refers to stars with masses between 8% and 120% of the mass of our Sun. In particular, I am interested in whether magnetic fields or magnetic activity (such as starspots, seen below on the Sun) play a significant role in determining the observed properties of stars. To do this, I compare predictions from theoretical stellar models to observations of both single stars and stars in binary systems (specifically eclipsing binaries). You can read about this here.

My curriculum vitae.

Team members Jessica Hamilton, Max Roberts, Khian Skidmore, and Dr. Feiden attended the Georgia Regional Astronomy Meeting (GRAM) at the University of Georgia. Jessica and Max presented posters showing results of their research projects. Learn more about their work on our research group page, or take a look at their posters, which are archived on Zenodo:
