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…
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…
Identification of the Top TESS Objects of Interest for Atmospheric Characterization of Transiting Exoplanets with JWST
Benjamin J. Hord, Eliza M. -R. Kempton, Thomas Mikal-Evans +142
JWST has ushered in an era of unprecedented ability to characterize exoplanetary atmospheres. While there are over 5,000 confirmed planets, more than 4,000 TESS planet candidates a…
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…
An extended low-density atmosphere around the Jupiter-sized planet WASP-193 b
Khalid Barkaoui, Francisco J. Pozuelos, Coel Hellier +32
Gas giants transiting bright nearby stars provide crucial insights into planetary system formation and evolution mechanisms. Most of these planets exhibit certain average character…
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…
Revisiting K2-233 spectroscopic time-series with multidimensional Gaussian Processes
Oscar Barragán, Edward Gillen, Suzanne Aigrain +7
Detecting planetary signatures in radial velocity time-series of young stars is challenging due to their inherently strong stellar activity. However, it is possible to learn inform…
Empirical Determination of the Lithium 6707.856 Å Wavelength in Young Stars
Justyn Campbell-White, Carlo F. Manara, Aurora Sicilia-Aguilar +20
Absorption features in stellar atmospheres are often used to calibrate photocentric velocities for kinematic analysis of further spectral lines. The Li feature at 6708 Å is…
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…
DREAM I. Orbital architecture orrery
V. Bourrier, O. Attia, M. Mallonn +28
The distribution of close-in exoplanets is shaped by a complex interplay between atmospheric and dynamical processes. The Desert-Rim Exoplanets Atmosphere and Migration (DREAM) pro…
