Search for Giant Planets around White Dwarfs with HST, Spitzer, and VLT
S. Friedrich, H. Zinnecker, S. Correia +3
For the last three years we have performed a survey for young (<3 Gyrs) giant planets around nearby white dwarfs with HST, Spitzer, and VLT. Direct HST/NICMOS imaging of the seven…
Theoretical mass loss rates of cool main-sequence stars
V. Holzwarth, M. Jardine
We develop a model for the wind properties of cool main-sequence stars, which comprises their wind ram pressures, mass fluxes, and terminal wind velocities. The wind properties are…
Absolute diffuse calibration of IRAC through mid-infrared and radio study of HII regions
Martin Cohen, Anne J. Green, Marilyn R. Meade +9
We investigate the diffuse absolute calibration of the InfraRed Array Camera on the Spitzer Space Telescope at 8.0microns using a sample of 43 HII regions with a wide range of morp…
Multi-site campaign on the open cluster M67. I. Observations and photometric reductions
D. Stello, T. Arentoft, T. R. Bedding +18
We report on an ambitious multi-site campaign aimed at detecting stellar variability, particularly solar-like oscillations, in the red giant stars in the open cluster M67 (NGC 2682…
A Time Delay for the Largest Gravitationally Lensed Quasar: SDSS J1004+4112
J. Fohlmeister, C. S. Kochanek, E. E. Falco +12
We present 426 epochs of optical monitoring data spanning 1000 days from December 2003 to June 2006 for the gravitationally lensed quasar SDSS J1004+4112. The time delay between th…
Discovery of an X-ray Jet and Extended Jet Structure in the Quasar PKS 1055+201
D. A. Schwartz, H. L. Marshall, J. E. J. Lovell +10
This letter reports rich X-ray jet structures found in the Chandra observation of PKS 1055+201. In addition to an X-ray jet coincident with the radio jet we detect a region of exte…
