Discovery and Characterization of the TOI-4468 Planetary System: A Transiting Hot Jupiter With a Lone Nearby Outer Companion
Joseph R. Livesey, Benjamin J. Hord, Juliette Becker +28
We report the discovery of two planets, a hot Jupiter and a nearby outer sub-Neptune, orbiting the star TOI-4468. This system is unique among the current exoplanet census in that i…
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…
The NEID Earth Twin Survey. II. Dynamical Masses in Seven High-acceleration Star Systems
Mark R. Giovinazzi, Cullen H. Blake, Paul Robertson +26
We present a set of companion dynamical masses and orbital parameters of seven star systems from the NEID Earth Twin Survey with significant absolute astrometric accelerations betw…
The True Stellar Obliquity of a Sub-Saturn Planet from the Tierras Observatory and KPF
Patrick Tamburo, Samuel W. Yee, Juliana GarcÃa-MejÃa +7
We measure the true obliquity of TOI-2364, a K dwarf with a sub-Saturn-mass () transiting planet on the upper edge of the hot Neptune desert. We used new Rossiter-…
