EPIC 219388192 b - an inhabitant of the brown dwarf desert in the Ruprecht 147 open cluster
Grzegorz Nowak, Enric Palle, Davide Gandolfi +32
We report the discovery of EPIC 219388192 b, a transiting brown dwarf in a 5.3-day orbit around a member star of Ruprecht-147, the oldest nearby open cluster association, which was…
K2-99: a subgiant hosting a transiting warm Jupiter in an eccentric orbit and a long-period companion
A. M. S. Smith, D. Gandolfi, O. Barragán +30
We report the discovery from K2 of a transiting planet in an 18.25-d, eccentric (0.19 0.04) orbit around K2-99, an 11th magnitude subgiant in Virgo. We confirm the planetary n…
WASP-86b and WASP-102b: super-dense versus bloated planets
F. Faedi, Y. Gómez Maqueo Chew, D. Pollacco +38
We report the discovery of two transiting planetary systems: a super dense, sub-Jupiter mass planet WASP-86b (\mpl\ = 0.82 0.06 \mj, \rpl\ = 0.63 0.01 \rj), and a bloat…
WASP-92b, WASP-93b and WASP-118b: Three new transiting close-in giant planets
K. L. Hay, A. Collier-Cameron, A. P. Doyle +36
We present the discovery of three new transiting giant planets, first detected with the WASP telescopes, and establish their planetary nature with follow up spectroscopy and ground…
From dense hot Jupiter to low-density Neptune: The discovery of WASP-127b, WASP-136b and WASP-138b
K. W. F. Lam, F. Faedi, D. J. A. Brown +38
We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18 +/- 0.02 M_J and radius 1.37 +/- 0.04 R_J. This is…
EPIC201702477b: A Long Period Transiting Brown Dwarf from K2
D. Bayliss, S. Hojjatpanah, A. Santerne +34
We report the discovery of EPIC201702477b, a transiting brown dwarf in a long period (40.73691 +/- 0.00037 day) and eccentric (e=0.2281 +/- 0.0026) orbit. This system was initially…
The K2-ESPRINT Project V: a short-period giant planet orbiting a subgiant star
Vincent Van Eylen, Simon Albrecht, Davide Gandolfi +31
We report on the discovery and characterization of the transiting planet K2-39b (EPIC 206247743b). With an orbital period of 4.6 days, it is the shortest-period planet orbiting a s…
Doppler Monitoring of five K2 Transiting Planetary Systems
Fei Dai, Joshua N. Winn, Simon Albrecht +21
In an effort to measure the masses of planets discovered by the NASA {\it K2} mission, we have conducted precise Doppler observations of five stars with transiting planets. We pres…
Earth's albedo variations 1998-2014 as measured from ground-based earthshine observations
E Palle, PR Goode, P Pilar Montanes-Rodriguez +11
The Earth's albedo is a fundamental climate parameter for understanding the radiation budget of the atmosphere. It has been traditionally measured from space platforms, but also fr…
Gray transits of WD 1145+017 over the visible band
R. Alonso, S. Rappaport, H. J. Deeg +1
We have observed several relatively deep transits of the white dwarf WD 1145+017 with the GTC over the wavelength range 480 nm to 920 nm. The observations covered approximately one…
Mass determination of K2-19b and K2-19c from radial velocities and transit timing variations
D. Nespral, D. Gandolfi, H. J. Deeg +21
We present FIES@NOT, HARPS-N@TNG, and [email protected] radial velocity follow-up observations of K2-19, a compact planetary system hosting three planets, of which the two larger ones…
Ruling out the orbital decay of the WASP-43b
Sergio Hoyer, Enric Palle, Diana Dragomir +1
We present 15 new transit observations of the exoplanet WASP-43b in the ,, and filters with the 1.0-m telescopes of Las Cumbres Observatory Global Telescope (LCOGT) Net…
Departure from the constant-period ephemeris for the transiting exoplanet WASP-12 b
G. Maciejewski, D. Dimitrov, M. Fernández +11
Most hot Jupiters are expected to spiral in towards their host stars due to transfering of the angular momentum of the orbital motion to the stellar spin. Their orbits can also pre…
The K2-ESPRINT Project II: Spectroscopic follow-up of three exoplanet systems from Campaign 1 of K2
Vincent Van Eylen, Grzegorz Nowak, Simon Albrecht +20
We report on Doppler observations of three transiting planet candidates that were detected during Campaign 1 of the K2 mission. The Doppler observations were conducted with FIES, H…
The K2-ESPRINT Project IV: A Hot Jupiter in a Prograde Orbit with a Possible Stellar Companion
Teruyuki Hirano, Grzegorz Nowak, Masayuki Kuzuhara +19
We report on the detection and early characterization of a hot Jupiter in a 3-day orbit around K2-34 (EPIC~212110888), a metal-rich F-type star located in the K2 Cycle 5 field. Our…
