A temperate exo-Earth around a quiet M dwarf at 3.4 parsecs

Xavier Bonfils, Nicola Astudillo-Defru, Rodrigo Díaz +12

The combination of high-contrast imaging and high-dispersion spectroscopy, which has successfully been used to detect the atmosphere of a giant planet, is one of the most promising…

Precise Masses in the WASP-47 System

Andrew Vanderburg, Juliette C. Becker, Lars A. Buchhave +32

We present precise radial velocity observations of WASP-47, a star known to host a hot Jupiter, a distant Jovian companion, and, uniquely, two additional transiting planets in shor…

The HARPS search for southern extra-solar planets XLII. A system of Earth-mass planets around the nearby M dwarf YZ Ceti

N. Astudillo-Defru, R. F. Díaz, X. Bonfils +13

Exoplanet surveys have shown that systems with multiple low-mass planets on compact orbits are common. Except for few cases, however, the masses of these planets are generally unkn…

Three's Company: An additional non-transiting super-Earth in the bright HD 3167 system, and masses for all three planets

Jessie L. Christiansen, Andrew Vanderburg, Jennifer Burt +55

HD 3167 is a bright (V = 8.9), nearby K0 star observed by the NASA K2 mission (EPIC 220383386), hosting two small, short-period transiting planets. Here we present the results of a…

Two massive rocky planets transiting a K-dwarf 6.5 parsecs away

Michael Gillon, Brice-Olivier Demory, Valerie Van Grootel +14

HD 219134 is a K-dwarf star at a distance of 6.5 parsecs around which several low-mass planets were recently discovered. The Spitzer space telescope detected a transit of the inner…
