Astronomy Colloquium
Colloquia are held every Wednesday during the academic year at 4pm in the Cahill Hameetman auditorium. Wine and cheese will be served in the Cahill Foyer from 5-5:30pm.
ASTRONOMY COLLOQUIUM
Modern synoptic surveys are revolutionizing our understanding of compact objects in binary systems. In this talk, I will highlight some recent advances in our understanding of white dwarfs, neutron stars, and black holes as a result of binary (and triple) systems. These results encompass phenomena which span orbital periods of 7 minutes to >70000 years, and have major implications in our understanding of compact object physics, as well as binary stellar evolution. I will conclude with a discussion of upcoming facilities including the Vera Rubin Observatory and LISA, and technological advances such as CMOS based imagers that will propel this field into its golden era.
ASTRONOMY COLLOQUIUM (Neugebauer Lecture)
I will show observations that probe the connections between disks and planets. I apply novel observational methods such as extreme adaptive optics, high-contrast imaging spectroscopy and infrared interferometry to studying the processes by which the ubiquitous disks around young stars form planets and then dissipate to leave mature planetary systems. First, disk structure can reveal the presence of planets too small to directly image. Second, disks present an opportunity to study the rocky precursors of planets, by taking advantage of the collisions that broke apart the parent bodies. Third, giant collisions can reveal both rocky materials and the processes that shape the final architectures of exoplanetary systems and planetary compositions.
