HRMOS White Paper: Science Motivation

Laura Magrini, Thomas Bensby, Anna Brucalassi +52

The High-Resolution Multi-Object Spectrograph (HRMOS) is a facility instrument that we plan to propose for the Very Large Telescope (VLT) of the European Southern Observatory (ESO)…

Planets around evolved intermediate-mass stars III. Planet candidates and long-term activity signals in six open clusters

E. Delgado Mena, J. Gomes da Silva, J. P. Faria +6

[abridged]The aim of this work is to search for planets around evolved stars, with a special focus on stars more massive than 2\,M in light of previous findings that show a…

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.…

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…
