Understanding eccentric temperate giants: an in-depth study of the architecture and stellar obliquity of the TOI-2134 system
Federica Rescigno, Manu Stalport, Ancy Anna John +28
We revisit the TOI-2134 planetary system with three new high-cadence TESS sectors and 98 more spectra. This new analysis confirms the two orbiting planets by simultaneously modelli…
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…
EBLM XVII - Tidal Synchronization and Circularization in Tight Stellar Binaries
Ritika Sethi, David V. Martin, Adrian Barker +7
Tidal interactions in close stellar binaries are central to their orbital and rotational evolution, making observational tests of theoretical predictions essential for our understa…
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 (…
A new photometric ephemeris for the 2M1510 AB double brown dwarf eclipsing binary system
Seb T. Millward, Vedad Kunovac
Eclipsing brown dwarfs are important calibrators of sub-stellar evolution models used to infer the characteristics of directly imaged brown dwarfs and giant exoplanets. Only two do…
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…
