The First Extrasolar Planet Discovered with a New Generation High Throughput Doppler Instrument

Abstract

We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new generation Doppler instrument. The planet orbits HD 102195, a young star with solar metallicity that may be part of the local association. The planet imparts radial velocity variability to the star with a semiamplitude of $63.4\pm 2.0$ m s${}^{-1}$ and a period of 4.11 days. The planetary minimum mass ($m\sin i$) is $0.488\pm 0.015$ $M_J$.
