The SOPHIE search for northern extrasolar planets. XIV. A temperate ( K) super-earth around the nearby star Gliese 411

R. F. Díaz, X. Delfosse, M. J. Hobson +33

Periodic radial velocity variations in the nearby M-dwarf star Gl411 are reported, based on measurements with the SOPHIE spectrograph. Current data do not allow us to distinguish b…

SOPHIE velocimetry of Kepler transit candidates. XIX. The transiting temperate giant planet KOI-3680b

G. Hebrard, A. S. Bonomo, R. F. Diaz +15

Whereas thousands of transiting giant exoplanets are known today, only a few are well characterized with long orbital periods. Here we present KOI-3680b, a new planet in this categ…

Fe I in the Beta Pictoris circumstellar gas disk. II. The time variations in the iron circumstellar gas

Flavien Kiefer, Alfred Vidal-Madjar, Alain Lecavelier des Etangs +5

Beta Pictoris is a young planetary system surrounded by a debris disk of dust and gas. The gas source of this disk could be exocomets (or 'falling and evaporating bodies', FEBs), w…

SOPHIE velocimetry of Kepler transit candidates XVIII. Radial velocity confirmation, absolute masses and radii, and origin of the Kepler-419 multiplanetary system

J. M. Almenara, R. F. Díaz, G. Hébrard +14

Kepler-419 is a planetary system discovered by the Kepler photometry which is known to harbour two massive giant planets: [...] Here we present new radial velocity (RV) measurement…

Fe I in the β Pictoris circumstellar gas disk I. Physical properties of the neutral iron gas

A. Vidal-Madjar, F. Kiefer, A. Lecavelier des Etangs +5

The young planetary system β Pictoris is surrounded by a circumstellar disk of dust and gas. Because both dust and gas have a lifetime shorter than the system age, they need to be…

The SOPHIE search for northern extrasolar planets. XI. Three new companions and an orbit update: Giant planets in the habitable zone

R. F. Díaz, J. Rey, O. Demangeon +25

We report the discovery of three new substellar companions to solar-type stars, HD191806, HD214823, and HD221585, based on radial velocity measurements obtained at the Haute-Proven…
