Astronomy Colloquium - Pauline Barmby

Cygnus X3 (Lia Corrales)
March 25, 2021
3:00 pm - 4:00 pm
ONLINE: Zoom Webinar

Nearby galaxies and their X-ray binaries 

X-ray binaries are probes of the physics of compact objects and stellar interactions. Multiwavelength identification of X-ray binaries provides a unique window on the star formation history and stellar evolution in nearby galaxies and their star clusters. Outstanding questions include: are X-ray binaries made or born? From what kinds of parent systems? This talk will describe recent studies of X-ray binaries in several nearby galaxies and what they tell us about dynamical interactions, stellar populations, galactic structure, and the physical processes occurring in the compact objects.
