A Spitzer Search for Infrared Excesses around Massive Young White Dwarfs
Brad M. S. Hansen, Shri Kulkarni, Sloane Wiktorowicz
We examine 14 hot white dwarfs for signs of infrared excess using the Spitzer Space Telescope. Twelve of the objects are massive white dwarfs which have been suggested to be the re…
White Dwarfs in NGC 6791: Avoiding the Helium Flash
Brad Hansen
We propose that the anomalously bright white dwarf luminosity function observed in NGC 6791 (Bedin et al 2005) is the consequence of the formation of 0.5 Msun white dwarfs with Hel…
On the Dayside Thermal Emission of Hot Jupiters
S. Seager, L. J. Richardson, B. M. S. Hansen +3
We discuss atmosphere models of HD209458b in light of the recent day-side flux measurement of HD209458b's secondary eclipse by Spitzer-MIPS at 24 microns. In addition, we present a…
The white dwarf cooling sequence in NGC 6791
L. R. Bedin, M. Salaris, G. Piotto +5
In the old, populous, and metal-rich open cluster NGC 6791 we have used deep HST/ACS images to track the white dwarf cooling sequence down to m_F606W~28.5. The white dwarf luminosi…
