TOI-332 b: a super dense Neptune found deep within the Neptunian desert

Ares Osborn, David J. Armstrong, Jorge Fernández Fernández +49

To date, thousands of planets have been discovered, but there are regions of the orbital parameter space that are still bare. An example is the short period and intermediate mass/r…

Discovery and characterisation of two Neptune-mass planets orbiting HD 212729 with TESS

David J. Armstrong, Ares Osborn, Vardan Adibekyan +33

We report the discovery of two exoplanets orbiting around HD 212729 (TOI\,1052, TIC 317060587), a K star with V=9.51 observed by TESS in Sectors 1 and 13. One exo…

TOI-908: a planet at the edge of the Neptune desert transiting a G-type star

Faith Hawthorn, Daniel Bayliss, David J. Armstrong +36

We present the discovery of an exoplanet transiting TOI-908 (TIC-350153977) using data from TESS sectors 1, 12, 13, 27, 28 and 39. TOI-908 is a T = 10.7 mag G-dwarf ( = 56…

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…

Three Saturn-mass planets transiting F-type stars revealed with TESS and HARPS

Angelica Psaridi, François Bouchy, Monika Lendl +62

While the sample of confirmed exoplanets continues to increase, the population of transiting exoplanets around early-type stars is still limited. These planets allow us to investig…
