"Convection in Cool Stars, as Revealed through Stellar Brightness Variations"

abstract

Fabienne Bastien

Pennsylvania State University

host: Adam Kraus or Bill Cochran

Sep. 15

"Compact Objects in Globular Clusters"

Compact objects in globular clusters are tracers of dynamical evolution of star clusters. They may also be the progenitors of exciting astrophysics events such as mergers between compact objects. I will discuss a few key results in this area, focusing on the discoveries of stellar mass black holes in globular clusters in our own Galaxy and nearby galaxies I will talk about the theoretical models that predicted such objects would not exist, and the observational evidence that they do exist. I will also show some additional new evidence for a double white dwarf system in our own Galactic globular cluster system which shows an orbital period of 18 minutes.
