New and updated convex shape models of asteroids based on optical data from a large collaboration network
J. HanuÅ¡, J. Äurech, D. A. Oszkiewicz +165
Asteroid modeling efforts in the last decade resulted in a comprehensive dataset of almost 400 convex shape models and their rotation states. This amount already provided a deep in…
EPIC211089792 b: an aligned and inflated hot jupiter in a young visual binary
A. Santerne, G. Hébrard, J. Lillo-Box +71
In the present paper we report the discovery of a new hot Jupiter, EPIC211089792 b, first detected by the Super-WASP observatory and then by the K2 space mission during its campaig…
Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations
J. Marques Oliveira, B. Sicardy, A. R. Gomes-Júnior +234
A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of…
The SOPHIE search for northern extrasolar planets. X. Detection and characterization of giant planets by the dozen
G. Hebrard, L. Arnold, T. Forveille +33
We present new radial velocity measurements of eight stars secured with the spectrograph SOPHIE at the 193-cm telescope of the Haute-Provence Observatory allowing the detection and…
SOPHIE velocimetry of Kepler transit candidates XII. KOI-1257 b: a highly eccentric three-month period transiting exoplanet
A. Santerne, G. Hébrard, M. Deleuil +36
In this paper we report a new transiting warm giant planet: KOI-1257 b. It was first detected in photometry as a planet-candidate by the space telescope and then val…
The SOPHIE search for northern extrasolar planets: VI. Three new hot Jupiters in multi-planet extrasolar systems
C. Moutou, G. Hebrard, F. Bouchy +21
We present high-precision radial-velocity measurements of three solar-type stars: HD 13908, HD 159243, and HIP 91258. The observations were made with the SOPHIE spectrograph at the…
