LOW-MASS COMPANIONS FOR FIVE SOLAR-TYPE STARS FROM THE MAGELLAN PLANET SEARCH PROGRAM
Abstract
We report low-mass companions orbiting five solar-type stars that have emerged from the Magellan precision Doppler velocity survey, with minimum (Msin i) masses ranging from 1.2 to 25 M JUP. These nearby target stars range from mildly metal-poor to metal-rich, and appear to have low chromospheric activity. The companions to the brightest two of these stars have previously been reported from the CORALIE survey. Four of these companions (HD 48265-b, HD 143361-b, HD 28185-b, and HD 111232-b) are low-mass Jupiter-like planets in eccentric intermediate- and long-period orbits. On the other hand, the companion to HD 43848 appears to be a long-period brown dwarf in a very eccentric orbit. © 2009. The American Astronomical Society. All rights reserved.
