The Polar Orbit of TOI-2374 b, a Planet in the Neptunian Ridge
Samuel W. Yee, Patrick Tamburo, Gudmundur Stefánsson +11
The ``Neptunian ridge'' is a recently identified peak in the frequency of planets with sizes between that of Neptune and Saturn orbiting their host stars with periods between 3 and…
Spot-Crossing Variations Confirm a Misaligned Orbit for a Planet Transiting an M Dwarf
Patrick Tamburo, Samuel W. Yee, Juliana GarcÃa-MejÃa +4
TOI-3884~b is an unusual 6.4~R planet orbiting an M4 host, whose transits display large and persistent spot-crossing events. We used the \textit{Tierras} Observatory to mo…
A transiting giant planet in orbit around a 0.2-solar-mass host star
Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56
Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…
TOI-6324b: An Earth-Mass Ultra-Short-Period Planet Transiting a Nearby M Dwarf
Rena A. Lee, Fei Dai, Andrew W. Howard +71
We report the confirmation of TOI-6324 b, an Earth-sized (1.059 0.041 R) ultra-short-period (USP) planet orbiting a nearby (20 pc) M dwarf. Using the newly com…
A giant planet transiting a 3-Myr protostar with a misaligned disk
Madyson G. Barber, Andrew W. Mann, Andrew Vanderburg +35
Astronomers have found more than a dozen planets transiting 10-40 million year old stars, but even younger transiting planets have remained elusive. A possible reason for the lack…
