Two Earth-size Planets and an Earth-size Candidate Transiting the Nearby Star HD 101581
Michelle Kunimoto, Zifan Lin, Sarah Millholland +43
We report the validation of multiple planets transiting the nearby ( pc) K5V dwarf HD 101581 (GJ 435, TOI-6276, TIC 397362481). The system consists of at least two Earth-…
Transiting Jupiters around M-dwarfs have similar masses to FGK warm-Jupiters
Shubham Kanodia
This paper presents a comparative analysis of the bulk properties (mass and radius) of transiting giant planets ( 8) orbiting FGKM stars. Our findings suggest…
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…
Searching for GEMS: Two Super-Jupiters around M-dwarfs -- Signatures of Instability or Accretion?
Andrew Hotnisky, Shubham Kanodia, Jessica Libby-Roberts +20
We present the discovery of TOI-6303b and TOI-6330b, two massive transiting super-Jupiters orbiting a M0 and a M2 star respectively, as part of the Searching for GEMS survey. These…
Origins of Super Jupiters: TOI-2145b Has a Moderately Eccentric and Nearly Aligned Orbit
Jiayin Dong, Ashley Chontos, George Zhou +15
Super Jupiters are giant planets with several Jupiter masses. It remains an open question whether these planets originate with such high masses or grow through collisions. Previous…
The First Spin-Orbit Obliquity of an M dwarf/brown dwarf System: An eccentric and aligned TOI-2119 b
Lauren Doyle, Caleb I. Cañas, Jessica E. Libby-Roberts +15
We report the first instance of an M dwarf/brown dwarf obliquity measurement for the TOI-2119 system using the Rossiter-McLaughlin effect. TOI-2119 b is a transiting brown dwarf or…
Gaia-4b and 5b: Radial Velocity Confirmation of Gaia Astrometric Orbital Solutions Reveal a Massive Planet and a Brown Dwarf Orbiting Low-mass Stars
Gudmundur Stefansson, Suvrath Mahadevan, Joshua Winn +31
Gaia astrometry of nearby stars is precise enough to detect the tiny displacements induced by substellar companions, but radial velocity data are needed for definitive confirmation…
Searching for GEMS: TOI-6383Ab, a giant planet transiting an M3-dwarf star in a binary system
Lia Marta Bernabò, Shubham Kanodia, Caleb I. Canas +22
We report on the discovery of a transiting giant planet around the 3500 K M3-dwarf star TOI-6383A located 172 pc from Earth. It was detected by the Transiting Exoplanet Survey Sate…
The NEID Earth Twin Survey. I. Confirmation of a 31-day planet orbiting HD 86728
Arvind F. Gupta, Jacob K. Luhn, Jason T. Wright +21
With close to three years of observations in hand, the NEID Earth Twin Survey (NETS) is starting to unearth new astrophysical signals for a curated sample of bright, radial velocit…
Searching for GEMS: TOI-5688 A b, a low-density giant orbiting a high-metallicity early M-dwarf
Varghese Reji, Shubham Kanodia, Joe Ninan +31
We present the discovery of a low-density planet orbiting the high-metallicity early M-dwarf TOI-5688 A b. This planet was characterized as part of the search for transiting giant…
Searching for GEMS: Characterizing Six Giant Planets around Cool Dwarfs
Shubham Kanodia, Arvind F. Gupta, Caleb I. Canas +42
Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an increasing…
Earths within Reach: Evaluation of Strategies for Mitigating Solar Variability using 3.5 years of NEID Sun-as-a-Star Observations
Eric B. Ford, Chad F. Bender, Cullen H. Blake +15
We present the results of Sun-as-a-star observations by the NEID Solar Telescope at WIYN Observatory, spanning January 1, 2021 through June 30, 2024. We identify 117,060 observatio…
Single-Star Warm-Jupiter Systems Tend to Be Aligned, Even Around Hot Stellar Hosts: No Dependency
