TOI-6692b: An eccentric 130 day period giant planet with a single transit from TESS

Allyson Bieryla, Karen A. Collins, George Zhou +46

We report the discovery and characterization of TOI-6692 b, an eccentric (e~0.54) Jupiter on a 130-day orbit. TOI-6692 b was first detected as a community TESS Object of Interest (…
