Hunting for the progenitor of SN 1006: High resolution spectroscopic search with the FLAMES instrument
Wolfgang E. Kerzendorf, Brian P. Schmidt, John B. Laird +2
Type Ia supernovae play a significant role in the evolution of the Universe and have a wide range of applications. It is widely believed that these events are the thermonuclear exp…
2M1938+4603: A rich, multimode pulsating sdB star with an eclipsing dM companion observed with Kepler
R. H. Østensen, E. M. Green, S. Bloemen +16
2M1938+4603 (KIC 9472174) displays a spectacular light curve dominated by a strong reflection effect and rather shallow, grazing eclipses. The orbital period is 0.126 days, the sec…
Modeling the System Parameters of 2M1533+3759: A New Longer-Period Low-Mass Eclipsing sdB+dM Binary
B. -Q. For, E. M. Green, G. Fontaine +17
We present new photometric and spectroscopic observations for 2M 1533+3759 (= NSVS 07826147). It has an orbital period of 0.16177042 day, significantly longer than the 2.3--3.0 hou…
A Keck HIRES Doppler Search for Planets Orbiting Metal-Poor Dwarfs. II. On the Frequency of Giant Planets in the Metal-Poor Regime
A. Sozzetti, G. Torres, D. W. Latham +5
We present an analysis of three years of precision radial velocity measurements of 160 metal-poor stars observed with HIRES on the Keck 1 telescope. We report on variability and lo…
A New Spectroscopic and Photometric Analysis of the Transiting Planet Systems TrES-3 and TrES-4
A. Sozzetti, G. Torres, D. Charbonneau +17
We report new spectroscopic and photometric observations of the parent stars of the recently discovered transiting planets TrES-3 and TrES-4. A detailed abundance analysis based on…
Rotation and Macroturbulence in Metal-poor Field Red Giant and Red Horizontal Branch Stars
Bruce W. Carney, David F. Gray, David Yong +4
We report the results for rotational velocities, Vrot sin i, and macroturbulence dispersion, zeta(RT), for 12 metal-poor field red giant branch stars and 7 metal-poor field red hor…
