Demographics of Close-In TESS Exoplanets Orbiting FGK Main-sequence Stars II. Spectral-Type Dependence and the Neptunian Landscape
Kaiming Cui, David J. Armstrong, Andreas Hadjigeorghiou +6
Understanding how planetary demographics depend on host star properties is essential for constraining planet formation and evolution theories. In this paper, we analyse close-in 0.…
Two extremely irradiated volatile-rich sub-Neptunes with companions in the TOI-426 and TOI-1839 systems: Insights into arrival and survival near the lower edge of the Neptunian desert
A. Castro-González, O. Barragán, D. J. Armstrong +26
Using TESS photometry and 147 HARPS radial velocities, we confirm two extremely irradiated, volatile-rich sub-Neptunes near the lower edge of the Neptunian desert: TOI-426 b and TO…
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…
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 (…
RAVEN: RAnking and Validation of ExoplaNets
Andreas Hadjigeorghiou, David J. Armstrong, Kaiming Cui +5
We present RAVEN, a newly developed vetting and validation pipeline for TESS exoplanet candidates. The pipeline employs a Bayesian framework to derive the posterior probability of…
The TOI-1117 Multi-planetary System: 3 sub-Neptunes, 1 in both the Neptunian Desert and Radius Valley
Isobel S. Lockley, David J. Armstrong, Jorge Fernández Fernández +33
We present the discovery of three sub-Neptune planets around TOI-1117, a Sun-like star with mass , radius , age Gyr and ef…
