A Local Baseline of the Black Hole Mass Scaling Relations for Active Galaxies. III. The BH mass - relation
Vardha N. Bennert, Tommaso Treu, Matthew W. Auger +6
We create a baseline of the black hole (BH) mass (MBH) - stellar-velocity dispersion (sigma) relation for active galaxies, using a sample of 66 local (0.02<z<0.09) Seyfert-1 galaxi…
Empirical Determination of Convection Parameters in White Dwarfs I : Whole Earth Telescope Observations of EC14012-1446
J. L. Provencal, M. H. Montgomery, A. Kanaan +55
We report on analysis of 308.3 hrs of high speed photometry targeting the pulsating DA white dwarf EC14012-1446. The data were acquired with the Whole Earth Telescope (WET) during…
Pulsational Mapping of Calcium Across the Surface of a White Dwarf
Susan E. Thompson, M. H. Montgomery, T. von Hippel +27
We constrain the distribution of calcium across the surface of the white dwarf star G29-38 by combining time series spectroscopy from Gemini-North with global time series photometr…
Two New Variable Hot DQ Stars
B. N. Barlow, B. H. Dunlap, R. Rosen +1
We have discovered periodic variations in the light curves of two hot DQ stars from the Sloan Digital Sky Survey, SDSS J220029.08-074121.5 and SDSS J234843.30-094245.3. These are t…
The pulsation modes of the pre-white dwarf PG 1159-035
J. E. S. Costa, S. O. Kepler, D. E. Winget +74
PG 1159-035, a pre-white dwarf with T_eff=140,000 K, is the prototype of both two classes: the PG1159 spectroscopic class and the DOV pulsating class. Previous studies of PG 1159-0…
