Star Talks on Saturday 8/22 Dr. Ted Gull, Eta Carina, and LRDs

Some of you might be interested in our special guest speakers at this Saturday evening's gathering.

 

Especially since Little Red Dots (LRDs) are in the news, now being called "Black Hole Stars" in the early universe, you maybe be interested in learning how the physics of these objects--with a dense cloud hiding a bright source--is similar to that for the Homunculus Nebula around the unusual bright variable star, Eta Carina!

 

Dr Ted Gull is a retired astrophysicist who worked 38 years at Goddard Space Flight Center. His degrees are from MIT and Cornell. He served as Deputy Principal Investigator for the Space Telescope Imaging Spectrograph that has operated for nearly three decades in the Hubble Space Telescope. Previously he was Mission Scientist responsible for Astro-1, a shuttle mission that flew on the Columbia in December 1990 carrying telescopes from Johns Hopkins, Goddard and University of Wisconsin. Much of his scientific research has been on Eta Carinae, a very massive binary that brightened to rival Sirius in the 1840s, faded, then brightened to a lesser degree in the 1890s. Over the past half century, Eta Carinae again has become visible to the naked eye.  Dr Gull has published over 600 scientific papers.

Timmy Stepnitz will be a freshman this year at nearby Western Tech High School. He is interested in the evolution of stars and will present an introduction to star types.

 

We hope you can join us for a special evening of presentations with all ages welcome!
