Separated twins or just siblings? A multi-planet system around an M dwarf including a cool sub-Neptune
Mallory Harris, Diana Dragomir, Ismael Mireles +27
We report the discovery of two TESS sub-Neptunes orbiting the early M dwarf TOI-904 (TIC 261257684). Both exoplanets, TOI-904 b and c, were initially observed in TESS Sector 12 wit…
TOI-858 B b: A hot Jupiter on a polar orbit in a loose binary
J. Hagelberg, L. D. Nielsen, O. Attia +30
We report the discovery of a hot Jupiter on a 3.28-day orbit around a 1.08 M G0 star that is the secondary component in a loose binary system. Based on follow-up radial vel…
A compact multi-planet system transiting HIP 29442 (TOI-469) discovered by TESS and ESPRESSO. Radial velocities lead to the detection of transits with low signal-to-noise ratio
M. Damasso, J. Rodrigues, A. Castro-González +52
We followed-up with ESPRESSO the K0V star HIP 29442 (TOI-469), already known to host a validated sub-Neptune companion TOI-469.01. We aim to verify the planetary nature of TOI-469.…
A Transiting Super-Earth in the Radius Valley and An Outer Planet Candidate Around HD 307842
Xinyan Hua, Sharon Xuesong Wang, Johanna K. Teske +32
We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD 307842 (TOI-784). The planet has a period of 2.8 days, and the radial veloci…
TOI-2498 b: A hot bloated super-Neptune within the Neptune desert
Ginger Frame, David J. Armstrong, Heather M. Cegla +39
We present the discovery and confirmation of a transiting hot, bloated Super-Neptune using photometry from TESS and LCOGT and radial velocity measurements from HARPS. The host star…
The young mini-Neptune HD 207496b that is either a naked core or on the verge of becoming one
S. C. C. Barros, O. D. S. Demangeon, D. J. Armstrong +40
We report the discovery and characterisation of the transiting mini-Neptune HD~207496~b (TOI-1099) as part of a large programme that aims to characterise naked core planets. We obt…
