Magnetic Star - Disk Interactions and Spin-Orbit Misalignment in Exoplanetary Systems
Dong Lai
11:00am|Bloomberg Hall Astrophysics Library
ABSTRACT: Recent observations have shown that in many exoplanetary systems, the spin axis of the parent star is misaligned with the angular momentum axis of the planet's orbit. This is unexpected as planets are formed in protostellar disks which are...

Sizes and Shapes of Drops Created in High Speed Impacts
Peter Goldreich
11:00am|Bloomberg Hall Astrophysics Library
ABSTRACT: High speed impacts of large bodies on Earth launch ejecta on trajectories that transport them thousands of kilometers from the impact site. These events are recorded in discrete layers of sub-millimeter size spherules in sea floor...

The Morphologies and Outflow Kinematics of Star Formation Quenching
Alison Coil
11:00am|Bloomberg Hall Astrophysics Library
ABSTRACT: Since z=1 the number of quiescent, non-star forming galaxies in the Universe has roughly doubled. In order to constrain the star formation quenching mechanism, I will present results on the clustering properties, morphologies, and...
