Discovery and Characterization of an Eccentric, Warm Saturn Transiting the Solar Analog TOI-4994

Romy Rodriguez Martinez, Jason D. Eastman, Karen Collins +46

We present the detection and characterization of TOI-4994b (TIC 277128619b), a warm Saturn-sized planet discovered by the NASA Transiting Exoplanet Survey Satellite (TESS). TOI-499…

Redshifted Sodium Transient near Exoplanet Transit

Apurva V. Oza, Julia V. Seidel, H. Jens Hoeijmakers +21

Neutral sodium (Na I) is an alkali metal with a favorable absorption cross section such that tenuous gases are easily illuminated at select transiting exoplanet systems. We examine…

The atmospheric composition of the ultra-hot Jupiter WASP-178 b observed with ESPRESSO

Y. C. Damasceno, J. V. Seidel, B. Prinoth +25

We search for atmospheric constituents for the UHJ WASP-178 b with two ESPRESSO transits using the narrow-band and cross-correlation techniques, focusing on the detections of NaI,…

HD 21520 b: a warm sub-Neptune transiting a bright G dwarf

Molly Nies, Ismael Mireles, François Bouchy +49

We report the discovery and validation of HD 21520 b, a transiting planet found with TESS and orbiting a bright G dwarf (V=9.2, K, $R_{\star} = 1.04\pm 0.02…

NGTS-30 b/TOI-4862 b: An 1 Gyr old 98-day transiting warm Jupiter

M. P. Battley, K. A. Collins, S. Ulmer-Moll +63

Long-period transiting exoplanets bridge the gap between the bulk of transit- and Doppler-based exoplanet discoveries, providing key insights into the formation and evolution of pl…

Discovery of two warm mini-Neptunes with contrasting densities orbiting the young K3V star TOI-815

Angelica Psaridi, Hugh Osborn, François Bouchy +130

We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal i…
