The Space Telescope Imaging Spectrograph (STIS) has been on orbit for approximately 16 years as one of the 2nd generation instruments on the Hubble Space Telescope (HST). Its operations were interrupted by an electronics ...
The solar twin planet search
(American Astronomical SocietyWashington, 2014)
We present preliminary results from an ongoing radial velocity planet search around solar twins using the HARPS spectrograph. By limiting our sample to stars with Teff +/- 100 K, log(g) +/- 0.1 dex, and [Fe/H] +/- 0.1 dex ...
