Radial and Rotational Velocities of a Volume-Complete Sample of M Dwarfs with Masses 0.1-0.3 Msun within 15 parsecs
Jennifer G. Winters, Emily K. Pass, David Charbonneau +7
We present the results from a five-year campaign to gather multi-epoch, high-resolution spectra of a volume-complete sample of 413 M dwarfs with masses 10-30% that of the Sun that…
Searching for Exoplanets Born Outside the Milky Way: VOYAGERS Survey Design
Robert Aloisi, Andrew Vanderburg, Melinda Soares-Furtado +44
Observations over the past few decades have found that planets are common around nearby stars in our Galaxy, but little is known about planets that formed outside the Milky Way. We…
An Eccentric Sub-Neptune Moving Into the Evaporation Desert
Sydney Jenkins, Andrew Vanderburg, Ritika Sethi +31
Though missions such as Kepler, K2, and TESS have discovered 2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P3 days) orbits. T…
An Oasis in the Brown Dwarf Desert: Confirmation of Two Low-mass Transiting Brown Dwarfs Discovered by TESS
Elina Y. Zhang, Theron W. Carmichael, Daniel Huber +14
As the intermediate-mass siblings of stars and planets, brown dwarfs (BDs) are vital to study for a better understanding of how objects change across the planet-to-star mass range.…
ExoMiner++: Enhanced Transit Classification and a New Vetting Catalog for 2-Minute TESS Data
Hamed Valizadegan, Miguel J. S. Martinho, Jon M. Jenkins +24
We present ExoMiner++, an enhanced deep learning model that builds on the success of ExoMiner to improve transit signal classification in 2-minute TESS data. ExoMiner++ incorporate…
11 New Transiting Brown Dwarfs and Very Low Mass Stars from TESS
Noah Vowell, Joseph E. Rodriguez, David W. Latham +39
We present the discovery of 11 new transiting brown dwarfs and low-mass M-dwarfs from NASA's TESS mission: TOI-2844, TOI-3122, TOI-3577, TOI-3755, TOI-4462, TOI-4635, TOI-4737, TOI…
