HD219666b: A hot-Neptune from TESS Sector 1

M. Esposito, D. J. Armstrong, D. Gandolfi +73

We report on the confirmation and mass determination of a transiting planet orbiting the old and inactive G7 dwarf star HD219666 (Mstar = 0.92 +/- 0.03 MSun, Rstar = 1.03 +/- 0.03…

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…

SWEET-Cat updated. New homogenous spectroscopic parameters

S. G. Sousa, V. Adibekyan, E. Delgado-Mena +14

Context: Exoplanets have now been proven to be very common. The number of its detections continues to grow following the development of better instruments and missions. One key ste…

K2-265 b: A Transiting Rocky Super-Earth

K. W. F. Lam, A. Santerne, S. G. Sousa +34

We report the discovery of the super-Earth K2-265 b detected with K2 photometry. The planet orbits a bright (V_mag = 11.1) star of spectral type G8V with a period of 2.37 days. We…

The SOPHIE search for northern extrasolar planets XIII. Two planets around M-dwarfs Gl617A and Gl96

M. J. Hobson, R. F. Díaz, X. Delfosse +32

We report the detection of two exoplanets and a further tentative candidate around the M-dwarf stars Gl96 and Gl617A, based on radial velocity measurements obtained with the SOPHIE…

An Earth-sized exoplanet with a Mercury-like composition

A. Santerne, B. Brugger, D. J. Armstrong +43

The Earth, Venus, Mars, and some extrasolar terrestrial planets have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle. A…

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…
