A SOPHIE RV search for giant planets around young nearby stars (YNS). A combination with the HARPS YNS survey
A. Grandjean, A. -M. Lagrange, N. Meunier +9
The search of close (a<=5 au) giant planet(GP) companions with radial velocity(RV) around young stars and the estimate of their occurrence rates is important to constrain the migra…
A search for a 5th planet around HR 8799 using the star-hopping RDI technique at VLT/SPHERE
Z. Wahhaj, J. Milli, C. Romero +8
The direct imaging of extrasolar giant planets demands the highest possible contrasts (dH ~10 magnitudes) at the smallest angular separations (~0.1'') from the star. We present an…
A HARPS RV search for planets around young nearby stars
A. Grandjean, A. -M. Lagrange, M. Keppler +9
Young nearby stars are good candidates in the search for planets with both radial velocity (RV) and direct imaging techniques. This, in turn, allows for the computation of the gian…
An unusually large gaseous transit in a debris disc
Daniela P. Iglesias, Johan Olofsson, Amelia Bayo +9
We present the detection of an unusually large transient gas absorption in several ionized species in the debris disc star HD 37306 using high-resolution optical spectra. We have b…
K2-287b: an Eccentric Warm Saturn transiting a G-dwarf
Andrés Jordán, Rafael Brahm, Néstor Espinoza +23
We report the discovery of K2-287b, a Saturn mass planet orbiting a G-dwarf with a period of days. First uncovered as a candidate using K2 campaign 15 data, follow-u…
EPIC 201498078b: A low density Super Neptune on an eccentric orbit
Rafael Brahm, Nestor Espinoza, Markus Rabus +15
We report the discovery of EPIC 201498078b, which was first identified as a planetary candidate from Kepler K2 photometry of Campaign 14, and whose planetary nature and orbital par…
EPIC229426032 b and EPIC246067459 b: discovery and characterization of two new transiting hot Jupiters from K2
M. G. Soto, M. R. Díaz, J. S. Jenkins +17
We report the discovery of two hot Jupiters orbiting the stars EPIC229426032 and EPIC246067459. We used photometric data from Campaign 11 and 12 of the Kepler K2 Mission and radial…
EPIC 228735255b - An eccentric 6.57 day transiting hot Jupiter in Virgo
H. A. C. Giles, D. Bayliss, N. Espinoza +25
We present the discovery of EPIC 228735255b, a P= 6.57 days Jupiter-mass (M=1.0190.070 M) planet transiting a V=12.5 (G5-spectral type) star in an eccentric orbit…
New Planetary Systems from the Calan-Hertfordshire Extrasolar Planet Search
J. S. Jenkins, H. R. A. Jones, M. Tuomi +22
We report the discovery of eight new giant planets, and updated orbits for four known planets, orbiting dwarf and subgiant stars using the CORALIE, HARPS, and MIKE instruments as p…
An independent discovery of two hot Jupiters from the K2 mission
Rafael Brahm, Matías Jones, Néstor Espinoza +9
We report the discovery of two hot Jupiters using photometry from Campaigns 4 and 5 of the two-wheeled Kepler (K2) mission. K2-30b has a mass of , a radius of $…
Discovery and Validation of a High-Density sub-Neptune from the K2 Mission
Néstor Espinoza, Rafael Brahm, Andrés Jordán +12
We report the discovery of BD+20594b, a high density sub-Neptune exoplanet, made using photometry from Campaign 4 of the two-wheeled Kepler (K2) mission, ground-based radial veloci…
