HIP 61637 b: a TESS Brown Dwarf in a Near-circular Orbit around a Massive A-type Star
Nino Ephremidze, David W. Latham, Perry Berlind +8
We present the characterization of HIP 61637 b (TOI-5401 b), a brown dwarf discovered by TESS to transit an A-type star. HIP 61637 is the most massive and the brightest star known…
Lithium Enrichment in a Subgiant Star with a Brown Dwarf Companion: A Planetary Engulfment Candidate
Brooke Kotten, Melinda Soares-Furtado, Ricardo Yarza +11
Theoretical models predict that subgiants within a narrow mass regime can retain detectable lithium enrichment signatures from planetary engulfment. We test this prediction using T…
An Ancient Brown Dwarf Transiting a Metal-Poor Thick Disk Star
Jéa Adams Redai, Vedant Chandra, Samuel W. Yee +20
We report the discovery of TOI-7019b, the first transiting brown dwarf (BD) known to orbit a star that is part of the Milky Way's ancient thick disk, as defined chemically ([Fe/H]…
The EBLM Project XVIII. 3D Obliquities of Five Low-Mass Eclipsing Binaries
Becca Spejcher, David V. Martin, Jake Pandina +17
The formation of tight stellar binaries remains an unsolved problem. There is too much angular momentum in a collapsing and fragmenting protostellar cloud to form a stellar binary…
The OATMEAL Survey. III. An Aligned Transiting Warm Brown Dwarf and Evidence for Quiescent Brown Dwarf Migration
Noah Vowell, Jiayin Dong, Joseph E. Rodriguez +7
We present the first measurement of the sky-projected orbital obliquity of a benchmark transiting brown dwarf host, HIP 33609, as a part of the Orbital Architectures of Transiting…
Migration and Evolution of giant ExoPlanets (MEEP) II: Super-Jupiters and Lithium-rich Host Stars
Jack Schulte, Joseph E. Rodriguez, David W. Latham +30
Although hot Jupiters were the first exoplanets discovered orbiting main sequence stars, the dominant mechanisms through which they form and evolve are not known. To address the qu…
The EBLM project XVI. Moderate spin-orbit misalignment of the low mass eclipsing binary EBLM J0021-16
Becca Spejcher, David V. Martin, Jake Pandina +15
Thousands of tight ( AU) main sequence binaries have been discovered, but it is uncertain how they formed. There is likely too much angular momentum in a collapsing, fragmentin…
The OATMEAL Survey. II. The 3D spin-orbit obliquity of an eccentric transiting brown dwarf in the Ruprecht 147 open cluster
Theron W. Carmichael, Steven Giacalone, Noah Vowell +11
We present new analysis of the CWW 89 system as part of the Orbital Architectures of Transiting Massive Exoplanets And Low-mass stars (OATMEAL) survey. The CWW 89 system is a membe…
TOI-2005b: An Eccentric Warm Jupiter in Spin-Orbit Alignment
Allyson Bieryla, Jiayin Dong, George Zhou +36
We report the discovery and characterization of TOI-2005b, a warm Jupiter on an eccentric (e~0.59), 17.3-day orbit around a V_mag = 9.867 rapidly rotating F-star. The object was de…
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…
The OATMEAL Survey. I. Low Stellar Obliquity in the Transiting Brown Dwarf System GPX-1
Steven Giacalone, Fei Dai, J. J. Zanazzi +31
We introduce the OATMEAL survey, an effort to measure the obliquities of stars with transiting brown dwarf companions. We observed a transit of the close-in ($P_{\rm orb} = 1.74 \,…
Migration and Evolution of giant ExoPlanets (MEEP) I: Nine Newly Confirmed Hot Jupiters from the TESS Mission
Jack Schulte, Joseph E. Rodriguez, Allyson Bieryla +72
Hot Jupiters were many of the first exoplanets discovered in the 1990s, but in the decades since their discovery, the mysteries surrounding their origins remain. Here, we present n…
Giant Outer Transiting Exoplanet Mass (GOT 'EM) Survey. IV. Long-term Doppler Spectroscopy for 11 Stars Thought to Host Cool Giant Exoplanets
Paul A. Dalba, Stephen R. Kane, Howard Isaacson +29
Discovering and characterizing exoplanets at the outer edge of the transit method's sensitivity has proven challenging owing to geometric biases and the practical difficulties asso…
Verification of Gaia DR3 Single-lined Spectroscopic Binary Solutions With Three Transiting Low-mass Secondaries
Stephen P. Schmidt, Kevin C. Schlaufman, Keyi Ding +18
While secondary mass inferences based on single-lined spectroscopic binary (SB1) solutions are subject to degeneracies, this degeneracy can be lifted through the observat…
HIP 33609 b: An Eccentric Brown Dwarf Transiting a V=7.3 Rapidly Rotating B-Star
Noah Vowell, Joseph E. Rodriguez, Samuel N. Quinn +41
We present the discovery and characterization of HIP 33609 b, a transiting warm brown dwarf orbiting a late B star, discovered by NASA's Transiting Exoplanet Survey Satellite TESS…
Another Shipment of Six Short-Period Giant Planets from TESS
Joseph E. Rodriguez, Samuel N. Quinn, Andrew Vanderburg +119
We present the discovery and characterization of six short-period, transiting giant planets from NASA's Transiting Exoplanet Survey Satellite (TESS) -- TOI-1811 (TIC 376524552), TO…
Ultraluminous X-ray Sources in Seven Edge-On Spiral Galaxies
Kristen C. Dage, Noah Vowell, Erica Thygesen +8
We investigate a sample of seven edge-on spiral galaxies using Chandra observations. Edge-on spiral galaxies allow us to clearly separate source associated with their star-forming…
