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…

TOI-1130: A photodynamical analysis of a hot Jupiter in resonance with an inner low-mass planet

J. Korth, D. Gandolfi, J. Šubjak +59

The TOI-1130 is a known planetary system around a K-dwarf consisting of a gas giant planet, TOI-1130 c, on an 8.4-day orbit, accompanied by an inner Neptune-sized planet, TOI-1130…

TOI-2046b, TOI-1181b and TOI-1516b, three new hot Jupiters from \textit{TESS}: planets orbiting a young star, a subgiant and a normal star

Petr Kabáth, Priyanka Chaturvedi, Phillip J. MacQueen +54

We present the confirmation and characterization of three hot Jupiters, TOI-1181b, TOI-1516b, and TOI-2046b, discovered by the TESS space mission. The reported hot Jupiters have or…

TOI-1268b: the youngest, hot, Saturn-mass transiting exoplanet

J. Šubjak, M. Endl, P. Chaturvedi +41

We report the discovery of TOI-1268b, a transiting Saturn-mass planet from the TESS space mission. With an age of less than one Gyr, derived from various age indicators, TOI-1268b…

The young HD 73583 (TOI-560) planetary system: Two 10-M mini-Neptunes transiting a 500-Myr-old, bright, and active K dwarf

O. Barragán, D. J. Armstrong, D. Gandolfi +103

We present the discovery and characterisation of two transiting planets observed by \textit{TESS} in the light curves of the young and bright (V=9.67) star HD73583 (TOI-560). We pe…

TOI-503: The first known brown dwarf-Am star binary from the TESS mission

Ján Šubjak, Rishikesh Sharma, Theron W. Carmichael +76

We report the discovery of an intermediate-mass transiting brown dwarf, TOI-503b, from the TESS mission. TOI-503b is the first brown dwarf discovered by TESS and orbits a metallic-…

Transit timing variations, radial velocities and long-term dynamical stability of the system Kepler-410

Pavol Gajdoš, Martin Vaňko, Theodor Pribulla +6

Transit timing variations of Kepler-410Ab were already reported in a few papers. Their semi-amplitude is about 14.5 minutes. In our previous paper, we found that the transit timing…
