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…
A giant exoplanet orbiting a very low-mass star challenges planet formation models
J. C. Morales, A. J. Mustill, I. Ribas +179
Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…
Radial velocity confirmation of K2-100b: a young, highly irradiated, and low density transiting hot Neptune
O. Barragán, S. Aigrain, D. Kubyshkina +37
We present a detailed analysis of HARPS-N radial velocity observations of K2-100, a young and active star in the Praesepe cluster, which hosts a transiting planet with a period of…
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-…
The Habitability of GJ 357 d : Possible Climates and Observability
L. Kaltenegger, J. Madden, Z. Lin +5
The GJ 357 system harbors 3 planets orbiting a bright, nearby M2.5V star at 9.44pc. The innermost planet GJ 357 b (TOI-562.01) is a hot transiting Earth-size planet with Earth-like…
