Andrew Sevrinsky, Junior Astronomer


Exciting updates:

I am pleased and grateful to announce that I've been awarded a 2016 Goldwater Scholarship. The Goldwater is a prestigious congressional scholarship for promising early-career STEM researchers.

I will be a summer intern at this year's Smithsonian Astrophysical Observatory REU. If you're in the Cambridge area and want to talk science, look me up!


I am currently a third year undergraduate physics major at Georgia State University in Atlanta. My specific interests lie with observational astronomy, especially of objects in the stellar regime. I am fortunate enough to be working as a research assistant as a junior member of RECONS with Dr. Todd Henry. In my capacity with RECONS, I am actively involved in helping to determine astrometric parallaxes of nearby low-mass stars.

I am currently working on a more specialized project. RECONS has a sample of nine unresolved binaries of late M spectral types for which photocentric orbits are available from the astrometric residuals. We recently obtained imagery of all nine systems using HST's WFC3 in an attempt to resolve the individual components. I am currently working on deriving separations and flux ratios for the resolved stars in this sample, which when combined with the existing photocentric orbits and trigonometric distances should yield very precise fractional masses for the components of these systems. The goal is to extend the mass-luminosity relation to the end of the main sequence where almost no well-constrained dynamical masses are currently available. Preliminary work on this project was presented at the 227th meeting of the American Astronomical Society in January 2016, and we anticipate submission of the publication by summer 2016.

I have been a volunteer at the annual Atlanta Star Party since its inception in 2009. This event, held in memory of astronomer Jeff Medkeff, both promotes astronomy amongst the general public and raises quite a bit of money for some very good causes every year. We took a hiatus in 2015, but expect to see the program back in 2016!
