Thermal Emission of Exoplanet XO-1b
Pavel Machalek, Peter R. McCullough, Christopher J. Burke +3
We estimate flux ratios of the extrasolar planet XO-1b to its host star XO-1 at 3.6, 4.5, 5.8 and 8.0 microns with the IRAC on the Spitzer Space Telescope to be 0.00086 +/- 0.00007…
UV and FUV spectroscopy of the hybrid PG 1159-type central star NGC 7094
M. Ziegler, T. Rauch, E. Reiff +3
Previous studies aiming at the iron-abundance determination in three PG 1159 stars (K 1-16, PG 1159-035, NGC 7094) and a [WC]-PG 1159 transition star (Abell 78) have revealed that…
O(He) Stars
T. Rauch, E. Reiff, K. Werner +1
Spectral analyses of H-deficient post-AGB stars have shown that a small group of four extremely hot objects exists which have almost pure He absorption-line spectra in the optical.…
First-Year Spectroscopy for the SDSS-II Supernova Survey
Chen Zheng, Roger W. Romani, Masao Sako +77
This paper presents spectroscopy of supernovae discovered in the first season of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for and measures multi-band…
The X-ray luminosity function of galaxies and its evolution
I. Georgantopoulos, P. Tzanavaris
We compile one of the largest ever samples to probe the X-ray normal galaxy luminosity function and its evolution with cosmic time. In particular, we select 207 galaxies (106 late…
Average Properties of a Large Sample of z_abs ~ z_em associated Mg II Absorption Line Systems
D. Vanden Berk, P. Khare, D. G. York +16
We have studied a sample of 415 associated (z_ab z_em; relative velocity with respect to QSO <3000km/s) Mg II absorption systems with 1.0<=z_ab<=1.86, in the spectra of SDSS DR3 QS…
