TOI-1670 c, a 40-day Orbital Period Warm Jupiter in a Compact System, is Well-aligned
Jack Lubin, Xian-Yu Wang, Malena Rice +21
We report the measurement of the sky-projected obliquity angle of the Warm Jovian exoplanet TOI-1670 c via the Rossiter-McLaughlin effect as part of the Stellar Obliquities in…
TOI-5344 b: A Saturn-like planet orbiting a super-Solar metallicity M0 dwarf
Te Han, Paul Robertson, Shubham Kanodia +19
We confirm the planetary nature of TOI-5344 b as a transiting giant exoplanet around an M0 dwarf star. TOI-5344 b was discovered with the Transiting Exoplanet Survey Satellite phot…
TOI-2015b: A Warm Neptune with Transit Timing Variations Orbiting an Active mid M Dwarf
Sinclaire E. Jones, Gudmundur Stefansson, Kento Masuda +29
We report the discovery of a close-in () warm Neptune with clear transit timing variations (TTVs) orbiting the nearby ($d=47.3\:\mathrm{pc}…
Astrometry and Precise Radial Velocities Yield a Complete Orbital Solution for the Nearby Eccentric Brown Dwarf LHS 1610 b
Evan Fitzmaurice, Gudmundur Stefánsson, Robert D. Kavanagh +18
The LHS 1610 system consists of a nearby ( pc) M5 dwarf hosting a candidate brown dwarf companion in a day, eccentric () orbit. We confirm this brown dwa…
The Extreme Stellar-Signals Project III. Combining Solar Data from HARPS, HARPS-N, EXPRES, and NEID
Lily L. Zhao, Xavier Dumusque, Eric B. Ford +37
We present an analysis of Sun-as-a-star observations from four different high-resolution, stabilized spectrographs -- HARPS, HARPS-N, EXPRES, and NEID. With simultaneous observatio…
Stable fiber-illumination for extremely precise radial velocities with NEID
Shubham Kanodia, Andrea S. J. Lin, Emily Lubar +24
NEID is a high-resolution red-optical precision radial velocity (RV) spectrograph recently commissioned at the WIYN 3.5 m telescope at Kitt Peak National Observatory, Arizona, USA.…
Measuring the Temperature of Starspots from Multi-Filter Photometry
Maria C. Schutte, Leslie Hebb, John P. Wisniewski +5
Using simultaneous multi-filter observations during the transit of an exoplanet around a K dwarf star, we determine the temperature of a starspot through modeling the radius and po…
TOI-4201: An Early M-dwarf Hosting a Massive Transiting Jupiter Stretching Theories of Core-Accretion
Megan Delamer, Shubham Kanodia, Caleb I. Cañas +24
We confirm TOI-4201 b as a transiting Jovian mass planet orbiting an early M dwarf discovered by the Transiting Exoplanet Survey Satellite. Using ground based photometry and precis…
TOI-3785 b: A Low-Density Neptune Orbiting an M2-Dwarf Star
Luke C. Powers, Jessica Libby-Roberts, Andrea S. J. Lin +19
Using both ground-based transit photometry and high-precision radial velocity (RV) spectroscopy, we confirm the planetary nature of TOI-3785 b. This transiting Neptune orbits an M2…
TOI-5375 B: A Very Low Mass Star at the Hydrogen-Burning Limit Orbiting an Early M-type Star
Mika Lambert, Chad F. Bender, Shubham Kanodia +16
The TESS mission detected a companion orbiting TIC 71268730, categorized it as a planet candidate, and designated the system TOI-5375. Our follow-up analysis using radial velocity…
A High-Eccentricity Warm Jupiter Orbiting TOI-4127
Arvind F. Gupta, Jonathan M. Jackson, Guillaume Hebrard +36
We report the discovery of TOI-4127 b, a transiting, Jupiter-sized exoplanet on a long-period ( d), high-eccentricity orbit around a late F-type…
An extreme test case for planet formation: a close-in Neptune orbiting an ultracool star
Gudmundur Stefansson, Suvrath Mahadevan, Yamila Miguel +27
In current theories of planet formation, close-orbiting planets as massive as Neptune are expected to be very rare around low-mass stars. We report the discovery of a Neptune-mass…
TOI-3984 A b and TOI-5293 A b: two temperate gas giants transiting mid-M dwarfs in wide binary systems
Caleb I. Cañas, Shubham Kanodia, Jessica Libby-Roberts +30
We confirm the planetary nature of two gas giants discovered by TESS to transit M dwarfs with stellar companions at wide separations. TOI-3984 A () is an M4 dwarf hosting…
