TAPIR Seminar

New populations of white dwarfs revealed by Gaia

Sihao Cheng, Postdoctoral Fellow, IAS, Princeton and Perimeter Institute,

In person: 370 Cahill -- Attendees joining in person must have a valid Caltech UID.

ABSTRACT: Data from the Gaia satellite are revolutionizing many fields of astronomy. I will present two discoveries about white dwarfs: one is an extreme cooling anomaly that poses a challenge for our understanding of white dwarf physics, and the other is the existence of merger products among single white dwarfs. I will show interesting solutions to the challenge and their implications for type-Ia supernovae and binary evolution.
