The frequency of planetary debris around young white dwarfs
D Koester, BT Gänsicke, J Farihi - Astronomy & Astrophysics, 2014 - aanda.org
Context. Heavy metals in the atmospheres of white dwarfs are thought in many cases to be
accreted from a circumstellar debris disk, which was formed by the tidal disruption of a rocky …

Protoplanetary disk lifetimes vs. stellar mass and possible implications for giant planet populations
Aims. We study the dependence of protoplanetary disk evolution on stellar mass using a
large sample of young stellar objects in nearby young star-forming regions. Methods. We …

The Apparently Decaying Orbit of WASP-12
We present new transit and occultation times for the hot Jupiter WASP-12b. The data are
compatible with a constant period derivative: $\dot {P}=-29\pm 3$ ms yr $^{-1} $ and $ P/\dot …
