TIC-320687387 B: a long-period eclipsing M-dwarf close to the hydrogen burning limit
Samuel Gill, Solene Ulmer-Moll, Peter J. Wheatley +26
We are using precise radial velocities from CORALIE together with precision photometry from the Next Generation Transit Survey (NGTS) to follow up stars with single-transit events…
Populating the brown dwarf and stellar boundary: Five stars with transiting companions near the hydrogen-burning mass limit
Nolan Grieves, François Bouchy, Monika Lendl +52
We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exopla…
TOI 694 b and TIC 220568520 b: Two Low-Mass Companions Near the Hydrogen Burning Mass Limit Orbiting Sun-like Stars
Ismael Mireles, Avi Shporer, Nolan Grieves +40
We report the discovery of TOI 694 b and TIC 220568520 b, two low-mass stellar companions in eccentric orbits around metal-rich Sun-like stars, first detected by the Transiting Exo…
The EBLM Project IV. Spectroscopic orbits of over 100 eclipsing M dwarfs masquerading as transiting hot-Jupiters
Amaury H. M. J. Triaud, David V. Martin, Damien Ségransan +15
We present 2271 radial velocity measurements taken on 118 single-line binary stars, taken over eight years with the CORALIE spectrograph. The binaries consist of F/G/K primaries an…
SOPHIE velocimetry of Kepler transit candidates. XIII. KOI-189 B and KOI-686 B: two very low-mass stars in long-period orbits
R. F. Díaz, G. Montagnier, J. Leconte +10
We present the radial-velocity follow-up of two Kepler planetary transiting candidates (KOI-189 and KOI-686) carried out with the SOPHIE spectrograph at the Observatoire de Haute P…
SOPHIE velocimetry of Kepler transit candidates. I. Detection of the low-mass white dwarf KOI-74b
David Ehrenreich, Anne-Marie Lagrange, François Bouchy +19
The Kepler mission has detected transits and occultations of a hot compact object around an early-type star, the Kepler Object of Interest KOI 74. The mass of this transiting objec…
