In this series of posts, we sit down with a few of the keynote speakers of the 235th AAS meeting to learn more about them and their research. You can see a full schedule of their talks here, and read our other interviews here!Dr. Andrea Dupree can’t get enough of spectra. A senior astrophysicist at the Harvard-Smithsonian Center for Astrophysics (CfA), Dupree has made significant contributions to stellar astrophysics using the technique of spectroscopy. “I’ve been a spectroscopist from the beginning,” she says, listing off the many wavelengths she has worked in. “You can find out amazing things from looking at these spectra.”

Stellar Stories Through Spectra
Dupree will share some of these insights applied to stellar accretion as a keynote speaker at AAS 235. Young stars accrete material, which then affects the stellar atmosphere. The stars later shed this material in the form of winds and jets—and we can watch this all occur by analyzing spectra. This story has ramifications beyond stars themselves. “This is all tied into the cycle of material in the galaxy and in the universe,” Dupree explains. The interaction between the stars and the interstellar medium is central to the narrative of galaxy formation, ...
