A distant brown dwarf coplanar to a warm Jupiter and a hot super-Earth

Matías I. Jones, Luca Naponiello, Trifon Trifonov +21

In transiting planetary systems, in which planetary sizes are accurately determined from transit observations, the presence of transit-timing variations (TTVs), especially when com…

Hidden massive eclipsing binaries in red supergiant systems: The hierarchical triple system KQ Puppis and other candidates

D. Jadlovský, L. Molnár, A. Ercolino +26

The majority of massive stars are part of binary systems that may interact during their evolution. However, not many RSGs are known binaries, and only a few have constrained orbita…

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…

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…

Constraining the size, shape, and albedo of the large Trans-Neptunian Object (28978) Ixion with multi-chord stellar occultations

Y. Kilic, F. Braga-Ribas, C. L. Pereira +81

Trans-Neptunian objects (TNOs) are among the most primitive remnants of the early Solar System, and constraining their sizes, shapes, albedos, and surface properties is essential f…
