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, Matías 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…
A Compact Multi-Planet System of Three Transiting Giant Planets Around TIC118798035
Rafael Brahm, Trifon Trifonov, Andrés Jordán +20
We report the discovery and characterization of three transiting giant planets in the TIC118798035 system. The three planets were identified as transiting candidates from data of t…
A Cold and Super-Puffy Planet on a Prograde Orbit
Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +36
We report the discovery of TOI-4507 b, a transiting sub-Saturn with a density 0.2 g/cm on a 105-day prograde orbit around a 700 Myr old F star. The transits were detected u…
Detection and characterisation of a 106-day transiting Jupiter : TOI-2449 b / NGTS-36 b
S. Ulmer-Moll, S. Gill, R. Brahm +64
Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects as their radius and mass can be measur…
NGTS-EB-7, an eccentric, long-period, low-mass eclipsing binary
Toby Rodel, Christopher. A. Watson, Solène Ulmer-Moll +35
Despite being the most common types of stars in the Galaxy, the physical properties of late M dwarfs are often poorly constrained. A trend of radius inflation compared to evolution…
Characterization of seven transiting systems including four warm Jupiters from SOPHIE and TESS
N. Heidari, G. H'ebrard, E. Martioli +65
We present the study of seven systems, three of which TOI-2295, TOI-2537, and TOI-5110 are newly discovered planetary systems. Through the analysis of TESS photometry, SOPHIE radia…
