Physics

Scientific paper

We are conducting several radial velocity surveys with the 9.2 m Hobby Eberly telescope (HET). These surveys are designed to improve our understanding of the physics of planetary system formation and evolution. We present recent results from two of these HET surveys. The first is from our survey of metal-poor stars. This survey is designed to probe the physics of planet formation at low metallicities. We present the detection of two planetary companions to HD 155358, a star with [Fe/H] of -0.68. This is the lowest metallicity of any planet host star.
