Anna Baum

Anna Baum's research has an overarching goal of understanding and characterizing stellar behavior. This goal has spanned a variety of subfields. She studied chromospheric activity in Sun-like stars across extensive time baselines in order to quantify periodic activity cycles like the Sun's and search for anomalistic or unique behavior; this led to the first discovery of a star entering a Maunder Minimum similar to the Sun's. She also utilizes eclipsing binary star systems to measure parameters of stars, and has combined this work with asteroseismology, the study of stellar oscillations. Stellar oscillations are also used to measure stellar parameters, and are an especially powerful tool when found in eclipsing binaries.
