On Signatures of Atmospheric Features in Thermal Phase Curves of Hot Jupiters
Emily Rauscher, Kristen Menou, James Y-K. Cho +2
Turbulence is ubiquitous in Solar System planetary atmospheres. In hot Jupiter atmospheres, the combination of moderately slow rotation and thick pressure scale height may result i…
Hypervelocity A & B Stars should be slow rotators
Brad Hansen
The most commonly accepted explanation for the origin of hypervelocity stars in the halo of the Milky Way is that they are the result of tidal disruption of binaries by the massive…
The Chemical Composition of an Extrasolar Minor Planet
B. Zuckerman, D. Koester, C. Melis +2
We report the relative abundances of 17 elements in the atmosphere of the white dwarf star GD 362, material that, very probably, was contained previously in a large asteroid or ast…
Cool Customers in the Stellar Graveyard IV: Spitzer Search for Mid-IR excesses Around Five DAs
J. H. Debes, S. Sigurdsson, B. Hansen
Hydrogen atmosphere white dwarfs with metal lines, so-called DAZs, require external accretion of material to explain the presence of weak metal line absorption in their photosphere…
The White Dwarf Cooling Sequence of NGC6397
Brad M. S. Hansen, Jay Anderson, James Brewer +10
We present the results of a deep Hubble Space Telescope (HST) exposure of the nearby globular cluster NGC6397, focussing attention on the cluster's white dwarf cooling sequence. Th…
Probing the Faintest Stars in a Globular Star Cluster
Harvey B. Richer, Jay Anderson, James Brewer +10
NGC 6397 is the second closest globular star cluster to the Sun. Using 5 days of time on the Hubble Space Telescope, we have constructed the deepest ever color-magnitude diagram fo…
