Gregory A. Feiden

Postdoctoral Fellow in Astronomy
Uppsala University


Hello and welcome! I am a postdoctoral fellow in astronomy at Uppsala University in Sweden. 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.
