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…
TOI-503: The first known brown dwarf-Am star binary from the TESS mission
Ján Šubjak, Rishikesh Sharma, Theron W. Carmichael +76
We report the discovery of an intermediate-mass transiting brown dwarf, TOI-503b, from the TESS mission. TOI-503b is the first brown dwarf discovered by TESS and orbits a metallic-…
It takes two planets in resonance to tango around K2-146
Kristine W. F. Lam, Judith Korth, Kento Masuda +51
K2-146 is a cool, 0.358 M_sun dwarf that was found to host a mini-Neptune with a 2.67-days period. The planet exhibited strong transit timing variations (TTVs) of greater than 30 m…
A super-Earth and sub-Neptune transiting the late-type M dwarf LP 791-18
Ian J. M. Crossfield, William Waalkes, Elisabeth R. Newton +57
Planets occur most frequently around cool dwarfs, but only a handful of specific examples are known to orbit the latest-type M stars. Using TESS photometry, we report the discovery…
Greening of the Brown Dwarf Desert. EPIC 212036875 b -- a 51 M object in a 5 day orbit around an F7 V star
Carina M. Persson, Szilárd Csizmadia, Alexander J. Mustill +55
Our aim is to investigate the nature and formation of brown dwarfs by adding a new well-characterised object to the small sample of less than 20 transiting brown dwarfs. One brown…
Monitoring of the D Doublet of Neutral Sodium during Transits of Two "Evaporating" Planets
Eric Gaidos, Teruyuki Hirano, Megan Ansdell
Spectroscopic transit detection of constituents in winds from "evaporating" planets on close-in transiting orbits could provide desperately needed information on the composition, f…
The Curious Case of KOI 4: Confirming Kepler's First Exoplanet
Ashley Chontos, Daniel Huber, David W. Latham +13
The discovery of thousands of planetary systems by Kepler has demonstrated that planets are ubiquitous. However, a major challenge has been the confirmation of Kepler planet candid…
The Transiting Multi-planet System HD15337: Two Nearly Equal-mass Planets Straddling the Radius Gap
Davide Gandolfi, Luca Fossati, John H. Livingston +53
We report the discovery of a super-Earth and a sub-Neptune transiting the star HD 15337 (TOI-402, TIC 120896927), a bright (V=9) K1 dwarf observed by the Transiting Exoplanet Surve…
K2-290: a warm Jupiter and a mini-Neptune in a triple-star system
M. Hjorth, A. B. Justesen, T. Hirano +41
We report the discovery of two transiting planets orbiting K2-290 (EPIC 249624646), a bright (V=11.11) late F-type star residing in a triple-star system. It was observed during Cam…
Spitzer transit follow-up of planet candidates from the K2 mission
John H. Livingston, Ian J. M. Crossfield, Michael W. Werner +21
We present precision 4.5 m Spitzer transit photometry of eight planet candidates discovered by the K2 mission: K2-52 b, K2-53 b, EPIC 205084841.01, K2-289 b, K2-174 b, K2-87 b,…
A Hot Saturn Orbiting An Oscillating Late Subgiant Discovered by TESS
Daniel Huber, William J. Chaplin, Ashley Chontos +139
We present the discovery of TOI-197.01, the first transiting planet identified by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology of the host star is po…
