Photodynamical analysis of the nearly resonant planetary system WASP-148: Accurate transit-timing variations and mutual orbital inclination
J. M. Almenara, G. Hébrard, R. F. Díaz +23
WASP-148 is a recently announced extra-solar system harbouring at least two giant planets. The inner planet transits its host star. The planets travel on eccentric orbits and are n…
HD207897 b: A dense sub-Neptune transiting a nearby and bright K-type star
N. Heidari, I. Boisse, J. Orell-Mique +90
We present the discovery and characterization of a transiting sub-Neptune orbiting with a 16.20 day period around a nearby (28 pc) and bright(V=8.37) K0V star HD207897 (TOI-1611).…
TIC 172900988: A Transiting Circumbinary Planet Detected in One Sector of TESS Data
Veselin B. Kostov, Brian P. Powell, Jerome A. Orosz +86
We report the first discovery of a transiting circumbinary planet detected from a single sector of TESS data. During Sector 21, the planet TIC 172900988b transited the primary star…
HAT-P-68b: A Transiting Hot Jupiter Around a K5 Dwarf Star
Bethlee M. Lindor, Joel D. Hartman, Gáspár Á. Bakos +24
We report the discovery by the ground-based HATNet survey of the transiting exoplanet HAT-P-68b, which has a mass of 0.724 0.043 , and radius of 1.072 0.012 $R…
The SOPHIE search for northern extrasolar planets XV. A Warm Neptune around the M-dwarf Gl378
M. J. Hobson, X. Delfosse, N. Astudillo-Defru +31
We present the detection of a Warm Neptune orbiting the M-dwarf Gl378, using radial velocity measurements obtained with the SOPHIE spectrograph at the Observatoire de Haute-Provenc…
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…
