Investigating the Earliest Phases of Massive Star Formation
Speaker: Professor Esteban D. Araya
Date: November 12, 2010 (Friday)
Time: 4 PM
Room: 205 Currens Hall


Massive stars - stars with more than eight times the mass of the Sun - are responsible for the enrichment of the interstellar medium with heavy elements and the existence
of extraordinary physical objects such as neutron stars and black holes. In this talk, I will review some of our current work on the study of massive star formation. In particular, the formation of massive stars within molecular filaments and the discovery of periodic maser flares of formaldehyde and methanol molecules, which could be caused by periodic accretion events onto young massive binaries.

About the speaker:
Professor Esteban Araya is a physics professor from the Department of Physics, Western Illinois University. His research focuses on the study of massive star formation and the interstellar medium. He carries out observations at radio frequencies with some of the most sophisticated radio telescopes.
