Associate Professor, Astronomy
Founding Director, Bridge to the Ph.D. Program in STEM
Professor Agüeros received his B.A. in Astronomy from Columbia College, earned an M.Phil in Physics from the University of Cambridge, UK, and then his Ph.D. in Astronomy from the University of Washington, Seattle. Before joining the Columbia faculty, he was a National Science Foundation (NSF) Astronomy and Astrophysics Postdoctoral Fellow in the Columbia Astrophysics Laboratory for four years. For two of those years, he was also the Associate Director of Columbia's Bridge to the Ph.D. Program in the Natural Sciences (now in STEM), which he directed for a decade. The Bridge Program website is here.
Professor Agüeros is a recipient of an NSF CAREER award, of the Presidential Early Career Award for Scientists and Engineers (PECASE), and has won Columbia University's Distinguished Faculty Award and its Presidential Teaching Award for Faculty.
time-domain astronomy, with a focus on stellar astrophysics; late stages of stellar evolution, especially white dwarfs
Professor Agüeros uses new datasets and technologies to address classic questions in stellar astrophysics. One example is an open cluster survey he is leading to calibrate the relationship between stellar age, rotation, and magnetic activity in low-mass stars. The existence of such a relationship was established over 40 years ago in solar-mass stars, but its exact form and theoretical underpinnings remain unknown. This has implications for stellar evolution and for observationally determining the ages of field stars.
