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…
Observational Tests of Planet Formation Models
A. Sozzetti, G. Torres, D. W. Latham +8
We summarize the results of two experiments to address important issues related to the correlation between planet frequencies and properties and the metallicity of the hosts. Our r…
Modeling the Galactic CV Distribution for the ChaMPlane Survey
A. B. Rogel, H. N. Cohn, P. M. Lugger
For purposes of designing targeted cataclysmic variable (CV) detection surveys and interpreting results of other projects with many CV detections such as the ChaMPlane Survey, we h…
Line Broadening in Field Metal-poor Red Giant and Red Horizontal Branch Stars
Bruce W. Carney, David W. Latham, R. P. Stefanik +1
We report 349 radial velocities for 45 metal-poor field red giant and red horizontal branch stars. We have have identified one new spectroscopic binary, HD 4306, and one possible s…
Discovery of Gas Accretion Onto Stars in 13 Myr old h and chi Persei
Thayne Currie, Scott Kenyon, Zoltan Balog +2
We report the discovery of accretion disks associated with ~ 13 Myr-old intermediate/low-mass stars in h and chi Persei. Optical spectroscopy of ~ 5000 stars in these clusters and…
The Rise and Fall of Debris Disks: MIPS Observations of h and chi Persei and the Evolution of Mid-IR Emission from Planet Formation
Thayne Currie, Scott Kenyon, Zoltan Balog +3
We describe Spitzer/MIPS observations of the double cluster, h and Persei, covering a 0.6 square-degree area surrounding the cores of both clusters. The data are combine…
