HIP 61637 b: a TESS Brown Dwarf in a Near-circular Orbit around a Massive A-type Star

Nino Ephremidze, David W. Latham, Perry Berlind +8

We present the characterization of HIP 61637 b (TOI-5401 b), a brown dwarf discovered by TESS to transit an A-type star. HIP 61637 is the most massive and the brightest star known…

CAFE follow-up of TESS hot Jupiter candidates left behind: I. Five newly confirmed planets and a false positive

J. Lillo-Box, C. Cifuentes, O. Balsalobre-Ruza +56

Hot Jupiters are key targets for understanding planet formation, migration, and atmospheres. Yet, most ground-based follow-up resources for the TESS mission are focused on confirmi…

NGTS-39 b: A 58 d transiting warm Jupiter in an eccentric orbit

Ioannis Apergis, Daniel Bayliss, Solène Ulmer-Moll +53

We report the discovery and characterisation of NGTS-39 b (TIC 453147896 b), a warm Jupiter transiting a Sun-like star on a 58.2 day, eccentric (e = 0.386 +/- 0.019) orbit. NGTS-39…

TOI-6884b: A low-mass brown dwarf transiting a slightly evolved star

Akanksha Khandelwal, Shubhendra Nath Das, Rishikesh Sharma +42

We report the discovery of a low-mass transiting brown dwarf orbiting TOI-6884 (TIC~156514476, ) from NASA's \textit{Transiting Exoplanet Survey Satellite} (\text…

Stellar Obliquities of Young Systems, Atmospheres Undergoing Contraction and Escape (SOYSAUCE) II: a 135 Myr planet on an aligned orbit with transit timing variations

Madyson G. Barber, Andrew W. Mann, Sydney Vach +16

Young planets (<1 Gyr) provide opportunities to directly probe planet formation and evolution processes in action. However, due to heightened stellar activity, there is a lack of k…

TOI-2147 b and TOI-6019 b: Two eccentric warm Jupiters detected and characterized with TESS and MaHPS

Luis Thomas, Louise D. Nielsen, Hanna Kellermann +36

The population of Jupiter-sized exoplanets with orbital periods between 10 and 200 days (WJs) exhibits a broad range of orbital eccentricities and system architectures, suggesting…
