TS23/McDonald and FIES/NOT strike again. Two new warm Jupiter systems and outer companions in a third
E. Knudstrup, D. Gandolfi, W. D. Cochran +29
Warm Jupiters (gas giant planets with orbital periods of P8-200 d) are thought to be largely unaffected by the tidal interactions that can erase information about the dynamic…
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…
An Ancient Brown Dwarf Transiting a Metal-Poor Thick Disk Star
Jéa Adams Redai, Vedant Chandra, Samuel W. Yee +20
We report the discovery of TOI-7019b, the first transiting brown dwarf (BD) known to orbit a star that is part of the Milky Way's ancient thick disk, as defined chemically ([Fe/H]…
