Two Jupiter-Mass Planets Orbiting HD 154672 and HD 205739
Mercedes Lopez-Morales, R. Paul Butler, Debra A. Fischer +6
We report the detection of the first two planets from the N2K Doppler planet search program at the Magellan telescopes. The first planet has a mass of M sin i = 4.96 M_Jup and is o…
The MagE Spectrograph
J. L. Marshall, Scott Burles, Ian B. Thompson +11
The Magellan Echellette (MagE) spectrograph is a single-object optical echellette spectrograph for the Magellan Clay telescope. MagE has been designed to have high throughput in th…
CS22964-161: A Double-Lined Carbon- and s-Process-Enhanced Metal-Poor Binary Star
Ian B. Thompson, Inese I. Ivans, Sara Bisterzo +6
A detailed high-resolution spectroscopic analysis is presented for the carbon-rich low metallicity Galactic halo object CS 22964-161. We have discovered that CS 22964-161 is a doub…
An Update on the 0Z Project
J. G. Cohen, N. Christlieb, A. McWilliam +2
We give an update on our 0Z Survey to find more extremely metal poor (EMP) stars with [Fe/H] < -3 dex through mining the database of the Hamburg/ESO Survey. We present the most ext…
New Extremely Metal-Poor Stars in the Galactic Halo
Judith G. Cohen, Norbert Christlieb, Andrew McWilliam +5
We present a detailed abundance analysis based on high resolution and high signal-to-noise spectra of eight extremely metal poor (EMP) stars with [Fe/H] < -3.5$ dex, four of which…
