B. Gladman, J. Coffey
We have examined the fate of impact ejecta liberated from the surface of Mercury due to impacts by comets or asteroids, in order to study (1) meteorite transfer to Earth, and (2) r…
On the Radial Distribution of White Dwarfs in the Globular Cluster NGC 6397
D. S. Davis, H. B. Richer, I. R. King +5
We have examined the radial distribution of white dwarfs over a single HST/ACS field in the nearby globular cluster NGC 6397. In relaxed populations, such as in a globular cluster,…
Rotation and activity of pre-main-sequence stars
Aleks Scholz, Jaime Coffey, Alexis Brandeker +1
We present a study of rotation (vsini) and chromospheric activity (Halpha EW) based on an extensive set of high-resolution optical spectra obtained with MIKE on the 6.5m Magellan C…
Accretion Disks around Young Stars: Lifetimes, Disk Locking and Variability
Ray Jayawardhana, Jaime Coffey, Alexander Scholz +2
We report the findings of a comprehensive study of disk accretion and related phenomena in four of the nearest young stellar associations spanning 6-30 million years in age, an epo…
