Carolina Science Cafe | Stellar Evolution, Interrupted

Open up any introductory astronomy textbook, and you can read about how stars like the Sun evolve from one stage of stellar evolution to the next. However, these textbook descriptions often overlook one important fact: most stars are in binary systems with other stellar or substellar companions, and their presence can greatly impact how the story of stellar evolution plays out.

In October’s Carolina Science Cafe, Dr. Brad Barlow, an Associate Professor of Physics & Astronomy at UNC-Chapel Hill, will discuss how his research group uses data from ground- and space-based observatories to discover and characterize special types of stars called hot subdwarfs that are the products of binary interactions. The broader impacts of this work touch on gravitational wave physics, Type Ia supernovae, the impact of late-stage stellar evolution on exoplanets, and more.

Designed for adults, Carolina Science Cafe explores science topics making national and international headlines and offers the chance to meet the experts behind the work. This special program is hosted at Haw River Tap & Table in Carrboro on the first Tuesday of every month. Light appetizers are available for all attendees.
