| This lecture will address a fundamental question of modern astrophysics: the origin of the elements, which is key to understanding the birth and childhood of our own Galaxy at a time when the Universe was still very young itself. To explore this early era, Dr. Frebel targets the oldest stars in the Galaxy and small dwarf galaxies, using their chemical composition to learn about the nature and conditions of their birth places at the time of their formation some 13 billion years ago. This way she can reconstruct what the very first stars might have been like and how the elements evolved. With information from these stars we are able to study how the galaxy assembled from many smaller and bigger galaxies into what we see today.
Speaker Bio
Dr. Frebel is currently a Fellow at Harvard Center for Astrophysics. Her research interests broadly cover the early Universe and how metal-poor stars can be used to obtain constraints on the first stars and initial mass function, supernova yields, and stellar nucleosynthesis. She is best known for her discoveries and subsequent spectroscopic analyses of the most metal-poor stars and how these stars can be employed to uncover information about the early Universe.
She did her undergraduate studies at the University of Freiburg in Germany and received her PhD from the Australian National University’s Mt. Stromlo Observatory in 2006, and has received a numerous awards for her work.
Please join us for a pre-meeting dinner discussion at Changsho, 1712 Mass Ave, Cambridge, MA at 6:00pm before the meeting. |
