Detailed Spectroscopic and Photometric Analysis of DQ White Dwarfs

We present an analysis of spectroscopic and photometric observations of cool DQ white dwarfs based on improved model atmosphere calculations. In particular , we revise the atmospheric parameters of the trigonometric parallax sample of Bergeron, Leggett, & Ruiz, and discuss the astrophysical implications on the temperature scale and mean mass, as well as the chemical evolution of these stars. We...

Eclipsing binaries in the Magellanic Clouds . ⋆ uvby CCD light curves and photometric analyses for HV 982 ( LMC ) , HV 12578 ( LMC ) , HV 1433 ( SMC ) , and HV 11284 ( SMC )

Eclipsing binaries in the Magellanic Clouds. ⋆ uvby CCD light curves and photometric analyses for Abstract. We present new accurate CCD uvby light curves for the LMC eclipsing binaries HV982 and HV12578, and for the SMC systems HV1433 and HV11284 obtained at the Danish 1.5m telescope at ESO, La Silla. The light curves were derived from DoPHOT photometry, and typical accuracies are between 0.007...

Spectroscopic Calibration of uBVRI Photometric Selection

We present a survey for z ∼ 3 Lyman break galaxies (LBGs) associated with damped Lyman α systems (DLAs) with the primary purpose of determining the DLA-LBG cross-correlation. This paper describes the acquisition and analysis of imaging and spectroscopic data of 9 quasar fields having 11 known z ∼ 3 DLAs covering an area of 465 arcmin. Using deep uBVRI images, 796 LBG candidates to an apparent R...
