AstroTours - Twists and Turns while Searching for Strange Stars (June 2022)

Описание: Speaker: Anna O'Grady (PhD Student at UofT and the Dunlap Institute)

Talk Abstract:

The scientific method, as we learned in schools, involves making a hypothesis and testing it to come to a final conclusion. But have you ever wondered what happens when the conclusions are different than expected? In this talk, I'll walk you through the process of trying to find Thorne-Zytkow Objects -- supergiant stars that have swallowed neutron stars. I'll explain how I identified and analyzed a group of interesting stars in another galaxy, and the unexpected twist along the way.
