The Hubble/STIS Near-ultraviolet Transmission Spectrum of HD 189733b
Patricio E. Cubillos, Luca Fossati, Tommi Koskinen +5
The benchmark hot Jupiter HD 189733b has been a key target to lay out the foundations of comparative planetology for giant exoplanets. As such, HD 189733b has been extensively stud…
Two transiting hot Jupiters from the WASP survey: WASP-150b and WASP-176b
Benjamin F. Cooke, Don Pollacco, Y. Almleaky +49
We report the discovery of two transiting exoplanets from the WASP survey, WASP-150b and WASP-176b. WASP-150b is an eccentric ( = 0.38) hot Jupiter on a 5.6 day orbit around a $…
Discovery and characterization of the exoplanets WASP-148b and c. A transiting system with two interacting giant planets
G. Hebrard, R. F. Diaz, A. C. M. Correia +39
We present the discovery and characterization of WASP-148, a new extrasolar system that includes at least two giant planets. The host star is a slowly rotating inactive late-G dwar…
The multi-planet system TOI-421 -- A warm Neptune and a super puffy mini-Neptune transiting a G9 V star in a visual binary
Ilaria Carleo, Davide Gandolfi, Oscar Barragán +110
We report the discovery of a warm Neptune and a hot sub-Neptune transiting TOI-421 (BD-14 1137, TIC 94986319), a bright (V=9.9) G9 dwarf star in a visual binary system observed by…
Three planets transiting the evolved star EPIC 249893012: a hot 8.8-M super-Earth and two warm 14.7 and 10.2-M sub-Neptunes
D. Hidalgo, E. Pallé, R. Alonso +57
We report the discovery of a new planetary system with three transiting planets, one super-Earth and two sub-Neptunes, that orbit EPIC\,249893012, a G8\,IV-V evolved star ($M_\star…
MuSCAT2 multicolour validation of TESS candidates: an ultra-short-period substellar object around an M dwarf
H. Parviainen, E. Palle, M. R. Zapatero-Osorio +37
We report the discovery of TOI 263.01 (TIC 120916706), a transiting substellar object (R = 0.87 RJup) orbiting a faint M3.5~V dwarf (V=18.97) on a 0.56~d orbit. We set out to deter…
Kojima-1Lb Is a Mildly Cold Neptune around the Brightest Microlensing Host Star
A. Fukui, D. Suzuki, N. Koshimoto +56
We report the analysis of additional multiband photometry and spectroscopy and new adaptive optics (AO) imaging of the nearby planetary microlensing event TCP J05074264+2447555 (Ko…
Detection and characterization of an ultra-dense sub-Neptune planet orbiting the Sun-like star HD 119130
R. Luque, G. Nowak, E. Pallé +51
We present the discovery and characterization of a new transiting planet from Campaign 17 of the Kepler extended mission K2. HD 119130 b is a warm sub-Neptune on a 17-d orbit aroun…
The GTC exoplanet transit spectroscopy survey IX. Detection of Haze, Na, K, and Li in the super-Neptune WASP-127b
G. Chen, E. Palle, L. Welbanks +9
Exoplanets with relatively clear atmospheres are prime targets for detailed studies of chemical compositions and abundances in their atmospheres. Alkali metals have long been sugge…
Super-Earth of 8 Mearth in a 2.2-day orbit around the K5V star K2-216
C. M. Persson, M. Fridlund, O. Barragán +35
The KESPRINT consortium identified K2-216 as a planetary candidate host star in the K2 space mission Campaign 8 field with a transiting super-Earth. The planet has recently been va…
Breaking the habit - the peculiar 2016 eruption of the unique recurrent nova M31N 2008-12a
M. Henze, M. J. Darnley, S. C. Williams +70
Since its discovery in 2008, the Andromeda galaxy nova M31N 2008-12a has been observed in eruption every single year. This unprecedented frequency indicates an extreme object, with…
K2-106, a system containing a metal-rich planet and a planet of lower density
E. W. Guenther, O. Barragan, F. Dai +42
Planets in the mass range from 2 to 15 MEarth are very diverse. Some of them have low densities, while others are very dense. By measuring the masses and radii, the mean densities,…
Multi-filter transit observations of HAT-P-3b and TrES-3b with multiple Northern Hemisphere telescopes
Davide Ricci, Pedro Valdés Sada, Samuel Navarro-Meza +17
We present a photometric follow-up of transiting exoplanets HAT-P-3b and TrES-3b, observed by using several optical and near-infrared filters, with four small-class telescopes (D =…
K2-31b, a grazing transiting hot Jupiter on an 1.26-day orbit around a bright G7V star
S. Grziwa, D. Gandolfi, Sz. Csizmadia +25
We report the discovery of K2-31b, the first confirmed transiting hot Jupiter detected by the K2 space mission. We combined K2 photometry with FastCam lucky imaging and FIES and HA…
