HATS-38 b and WASP-139 b join a growing group of hot Neptunes on polar orbits

Juan I. Espinoza-Retamal, Guðmundur Stefánsson, Cristobal Petrovich +9

We constrain the sky-projected obliquities of two low-density hot Neptune planets, HATS-38 b and WASP-139 b, orbiting nearby G and K stars using Rossiter-McLaughlin (RM) observatio…

TOI-2490b- The most eccentric brown dwarf transiting in the brown dwarf desert

Beth A. Henderson, Sarah L. Casewell, Andrés Jordán +40

We report the discovery of the most eccentric transiting brown dwarf in the brown dwarf desert, TOI02490b. The brown dwarf desert is the lack of brown dwarfs around main sequence s…

Spectroscopy of Eclipsing Compact Hierarchical Triples I

Ayush Moharana, K. G. Hełminiak, F. Marcadon +6

Eclipsing Compact Hierarchical Triples (ECHTs) are systems with the tertiary star orbiting an eclipsing binary (EB) in an orbit of fewer than 1000 days. In a CHT, all three stars e…
