POSEIDON I: The Dynamical Origins of Transiting Neptunes
Juan I. Espinoza-Retamal, Joshua N. Winn, Rafael Brahm +17
We present the first results from the POSEIDON survey, aimed at constraining the dynamical origins of transiting Neptunes through stellar obliquity measurements. We report Rossiter…
HATPI Pre-Perihelion Time-series Photometry of the Interstellar Comet 3I/ATLAS
Joel D. Hartman, Gáspár Ã. Bakos, Andrés Jordán +10
HATPI is a recently commissioned time-domain facility at Las Campanas Observatory, Chile, that uses 64 wide-angle, 9.6 cm diameter lenses and back-illuminated CCDs, yielding a mosa…
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…
Two warm sub-Saturn mass planets identified from the TESS Full Frame Images
Felipe I. Rojas, Rafael Brahm, Andrés Jordán +47
Context. Characterization of warm giants is crucial to constrain giant planet formation and evolution. Measuring the mass and radius of these planets, combined with their moderated…
TIC65910228b: A single-transit discovery of a massive long-period warm Jupiter with TESS
Felipe I. Rojas, Rafael Brahm, MatÃas I. Jones +27
Context. Warm Jupiters are excellent case studies for the investigation of giant planet internal structures and formation theories. However, the sample of long-period transiting gi…
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…
