Faculty Profile: Marcel Agüeros

Marcel Agüeros

Bio

Professor Agüeros received his B.A. in Astronomy from Columbia University before earning an M.Phil in Physics from the University of Cambridge (UK) and his Ph.D. in Astronomy from the University of Washington. Before joining the Columbia faculty, he was a National Science Foundation 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, which he now directs.

Professor Agüeros's interest lies in using new datasets and technologies to address classic questions in stellar astrophysics. One example is his work using Palomar Transient Factory data to obtain rotational periods for low-mass stars. This is part of an open cluster survey he is leading to calibrate the relationship between stellar age, rotation and magnetic activity. 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.
