TOI-3664 b, TOI-4034 b & TOI-6564 b: Three new hot Jupiters around stars approaching the terminal age main sequence
Matthew P. Battley, Marina Lafarga, Edward Gillen +21
Studying the evolution of hot Jupiters requires a sample of well-characterised systems across all evolutionary states. We present three new gas giant exoplanets around stars approa…
Automatic search for transiting planets in TESS-SPOC FFIs with RAVEN: over 100 newly validated planets and over 2000 vetted candidates
M. Lafarga, D. J. Armstrong, K. Cui +7
Space-based missions such as TESS are identifying a wealth of short-period ( d) transiting planets. Despite the growing number of confirmed and candidate planets, the s…
Long-period magnetic activity in the K dwarf GJ 1137 and a new super-Earth on a 9-day orbit
Denitza Stoeva, Atanas K. Stefanov, Stefan Y. Stefanov +12
Aims: We investigate long-term radial velocity (RV) variability in the K-dwarf star GJ 1137 (HD 93083, HIP52521), a known Saturn-mass exoplanet host, and assess the role of stellar…
Demographics of Close-In TESS Exoplanets Orbiting FGK Main-sequence Stars
Kaiming Cui, David J. Armstrong, Andreas Hadjigeorghiou +5
Understanding the demographics of close-in planets is crucial for insights into exoplanet formation and evolution. We present a detailed analysis of occurrence rates for close-in (…
Mass estimates of the young TOI-451 transiting planets: Multidimensional Gaussian Process on stellar spectroscopic and photometric signals
Oscar Barragán, Manuel Mallorquín, Jorge Fernández-Fernández +30
The young TOI-451 planetary system, aged 125 Myr, provides a unique opportunity to test theories of planetary internal structures and atmospheric mass loss through examination of i…
Resolving star spots on WASP-85 A using high-resolution transit spectroscopy
Vedad Kunovac, Heather Cegla, Hritam Chakraborty +23
Stellar surface inhomogeneities such as spots and faculae introduce Doppler variations that challenge exoplanet detection via the radial velocity method. While their impact on disc…
Astroclimes -- measuring the abundance of CO and CH in the Earth's atmosphere using astronomical observations
Marcelo Aron Fetzner Keniger, David Armstrong, Matteo Brogi +2
Monitoring the abundance of greenhouse gases (GHGs) such as carbon dioxide (CO) and methane (CH) is necessary to quantify their impact on global warming and climate change.…
Exploring the Neptunian Desert: Insights from a Homogeneous Planetary Sample
Lauren Doyle, David J. Armstrong, Lorena Acuña +26
In this paper, we present a homogeneous analysis of close-in Neptune planets. To do this, we compile a sample of TESS-observed planets using a ranking criterion which takes into ac…
Detectability of oxygen fugacity regimes in the magma ocean world 55 Cancri e at high spectral resolution
Spandan Dash, Matteo Brogi, Fabian Lukas Seidler +5
Ultra-short Period exoplanets (USPs) like 55 Cnc e, hosting dayside magma oceans, present unique opportunities to study surface-atmosphere interactions. The composition of a vapori…
The First Spin-Orbit Obliquity of an M dwarf/brown dwarf System: An eccentric and aligned TOI-2119 b
Lauren Doyle, Caleb I. Cañas, Jessica E. Libby-Roberts +15
We report the first instance of an M dwarf/brown dwarf obliquity measurement for the TOI-2119 system using the Rossiter-McLaughlin effect. TOI-2119 b is a transiting brown dwarf or…
The mystery of water in the atmosphere of Boötis b continues: insights from revisiting archival CRIRES observations
Vatsal Panwar, Matteo Brogi, Siddharth Gandhi +2
The chemical abundances of gas-giant exoplanet atmospheres hold clues to the formation and evolution pathways that sculpt the exoplanet population. Recent ground-based high-resolut…
