TL;DR
This paper reports the discovery of three new exoplanets orbiting solar-type stars using radial velocity measurements, expanding the known diversity of planetary systems with longer, eccentric orbits and higher masses.
Contribution
It presents the detection of three new extrasolar planets with longer, eccentric orbits, and provides additional radial velocity data for known planetary systems.
Findings
Discovered 3 new planets with 1-3.3 M_Jup masses.
Planets have longer, eccentric orbits than typical hot Jupiters.
Stars hosting these planets are metal-rich.
Abstract
We report the detection of 3 new planetary companions orbiting the solar-type stars GJ 3021, HD 52265 and HD 169830 using radial-velocity measurements taken with the CORALIE echelle spectrograph. All these planetary companions have longer orbital periods than the 51 Peg-like objects. The orbits are fairly eccentric. The minimum masses of these planets range from 1 to 3.3 M_Jup. The stars have spectral types from F8V to G6V. They are metal-rich. We also present our radial-velocity measurements for three solar-type stars known to host planetary companions iota Hor (HD 17051), HD 210277 and HD 217107.
