The TOI-763 system: sub-Neptunes orbiting a Sun-like star
M. Fridlund, J. Livingston, D. Gandolfi +51
We report the discovery of a planetary system orbiting TOI-763 (aka CD-39 7945), a , high proper motion G-type dwarf star that was photometrically monitored by the TESS spa…
Mass determinations of the three mini-Neptunes transiting TOI-125
L. D. Nielsen, D. Gandolfi, D. J. Armstrong +77
The Transiting Exoplanet Survey Satellite, TESS, is currently carrying out an all-sky search for small planets transiting bright stars. In the first year of the TESS survey, steady…
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…
Precise radial velocities of giant stars XIII. A second Jupiter orbiting in 4:3 resonance in the 7 CMa system
R. Luque, T. Trifonov, S. Reffert +8
We report the discovery of a second planet orbiting the K giant star 7 CMa based on 166 high-precision radial velocities obtained with Lick, HARPS, UCLES and SONG. The periodogram…
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…
