The Longest-period Young Transiting Exoplanets. A Duo of Puffy Giants inside a Debris Disk
Carlos del Burgo, Alejandro Suárez Mascareño, Ana Heras Pastor +35
We identify two large-radius planets around the F-type star HD 114082 as the longest-period young transiting exoplanets known. From the first transit, detected by NASA's Transiting…
Bessel-Hagen currents for the Fierz-Pauli action
Michael Hobson, Will Barker, Anthony Lasenby
For electromagnetism in Minkowski spacetime, the Bessel-Hagen method gives a particularly direct Noetherian derivation of the standard gauge-invariant energy-momentum tensor. The k…
The multi-planet system TOI-5624: Four transiting sub-Neptunes with an outer companion revealed by transit-timing variations
A. Bonfanti, D. Gandolfi, P. Leonardi +96
Following the 2022 alert of a TESS object of interest transiting TOI-5624 (a G7 V star 100 pc away), a CHEOPS campaign in 2023 detected four planetary signals at $P_b\approx3…
Time delays and stationarity in quasar light curves
Namu Kroupa, David Yallup, Will Handley
We present a fully Bayesian framework for time delay inference and stationarity tests in quasar light curves using marginalised Gaussian processes. The model separates a determinis…
PLATOSpec's first results: Three new transiting warm Jupiters from the WINE survey TIC 147027702, TIC 245076932 and TIC 87422071
Pavol Gajdoš, Rafael Brahm, Lorena Acuña-Aguirre +33
We report the discovery and characterisation of three transiting warm Jupiters: TIC 147027702b, TIC 245076932b and TIC 87422071b. These systems were initially identified as transit…
Unraveling the Brown Dwarf Desert: Four New Discoveries and a Unifying, Period-Coded Picture
Ján Šubjak, Rafael Brahm, Jozef Lipták +30
We present four newly validated transiting brown dwarfs identified through TESS photometry and confirmed with high-precision radial velocity measurements obtained from the FEROS an…
