From SCIENCE CAFÉS BGSU
“Variable Stars: Clues to Comprehending the Cosmos” presented by Andrew Layden will be the theme of the next Science Cafe, Tuesday, June 18, from 6-7 p.m.
The event will be hybrid with a live presentation at Juniper Brewing Company, 145 S. Main St., Bowling Green, which will available via Zoom. The event is free but registration is requested.
A small fraction of stars change their brightness over time. The causes are many and varied; one cause is pulsation, the periodic expansion and contraction of the star. The discussion will focus on the process, the evidence, and the utility of these stars to an observational science where traditional controlled experiments are not possible.
The talk will last about 30 minutes and is aimed at the general public and will be followed by about 30 minutes of Q&A and discussion with the speaker and others involved in the research.
Layden is in the department of Department of Physics & Astronomy at BGSU. He grew up near Hartford, Connecticut and got interested in physics in high school, then astronomy in college. Layden has worked with ground based-telescopes, both large and small, in both hemispheres, as well as the Hubble Space Telescope.
Refreshments will be provided.
