Optical Images of an Exosolar Planet 25 Light Years from Earth
Paul Kalas, James R. Graham, Eugene Chiang +6
Fomalhaut is a bright star 7.7 parsecs (25 light years) from Earth that harbors a belt of cold dust with a structure consistent with gravitational sculpting by an orbiting planet.…
Atmospheric Escape from Hot Jupiters
Ruth Murray-Clay, Eugene Chiang, Norman Murray
Photoionization heating from UV radiation incident on the atmospheres of hot Jupiters may drive planetary mass loss. We construct a model of escape that includes realistic heating…
Full Numerical Simulations of Catastrophic Small Body Collisions
Zoe M. Leinhardt, Sarah T. Stewart
The outcome of collisions between small icy bodies, such as Kuiper belt objects, is poorly understood and yet a critical component of the evolution of the trans-Neptunian region. T…
A High Precision, Optical Polarimeter to Measure Inclinations of High Mass X-Ray Binaries
Sloane J. Wiktorowicz, Keith Matthews
We present commissioning data for the POLISH instrument obtained on the Hale 5-m telescope. The goal of this high precision polarimeter is to constrain orbital inclination of high…
Empirical Models of Pressure and Density in Saturn's Interior: Implications for the Helium Concentration, its Depth Dependence, and Saturn's Precession Rate
Ravit Helled, Gerald Schubert, John D. Anderson
We present 'empirical' models (pressure vs. density) of Saturn's interior constrained by the gravitational coefficients J_2, J_4, and J_6 for different assumed rotation rates of th…
Photochemical enrichment of deuterium in Titan's atmosphere: new insights from Cassini-Huygens
D. Cordier, O. Mousis, I. J. Lunine +2
Cassini-Huygens data are used to re-examine the potential sources of the D/H enhancement over solar, measured in methane, in Titan's atmosphere. Assuming that the system is closed…
