ML-Astro Talks: The ages, rotation periods, and magnetic activity of stars
Special Event | May 7 | 3-4 p.m. | 131 Campbell Hall
In this talk Ruth Angus, PhD. will be speaking on her research about stars, planets and, statistics with an important ML component. She will describe how to measure state-of-the-art stellar ages by combing information from different evolutionary processes, including hydrogen burning and magnetic braking. Dr. Angus will also describe the process of measuring stellar rotation periods, including why this is hard, all the various pitfalls, and how we can improve it. Finally, she will discuss how we might measure the ages and other properties of stars from time-series brightness variations of stars (light curves) directly, without using summary statistics to translate from light curve to age.
Dr. Ruth Angus (AMNH, New York) is currently Assistant Curator of Astrophysics at the American Museum of Natural History (New York), Associate Research Scientist at the Flatiron Institue, and Adjunct Professor of Astronomy at Columbia University.
