Classical Cases of Non-solar Mixing Length in Low Mass Stars
Rebecca Woody, Charlie Conroy, Phillip A. Cargile +1
The treatment of convection is one of the largest remaining uncertainties in models of low mass stars. The Mixing Length Theory (MLT) for super-adiabatic convection has come under…
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]…
All-Sky Kinematics of the Distant Halo: The Reflex Response to the LMC
Vedant Chandra, Rohan P. Naidu, Charlie Conroy +11
The infall of the Large Magellanic Cloud (LMC) is predicted to displace the inner Milky Way (MW), imprinting an apparent 'reflex motion' on the observed velocities of distant halo…
Distant Echoes of the Milky Way's Last Major Merger
Vedant Chandra, Rohan P. Naidu, Charlie Conroy +9
The majority of the Milky Way's stellar halo consists of debris from our Galaxy's last major merger, the Gaia-Sausage-Enceladus (GSE). In the past few years, stars from GSE have be…
The Stellar Halo of the Galaxy is Tilted & Doubly Broken
Jiwon Jesse Han, Charlie Conroy, Benjamin D. Johnson +7
Modern Galactic surveys have revealed an ancient merger that dominates the stellar halo of our Galaxy (\textit{Gaia}-Sausage-Enceladus, GSE). Using chemical abundances and kinemati…
A Ghost in Boötes: The Least Luminous Disrupted Dwarf Galaxy
Vedant Chandra, Charlie Conroy, Nelson Caldwell +9
We report the discovery of Specter, a disrupted ultrafaint dwarf galaxy revealed by the H3 Spectroscopic Survey. We detected this structure via a pair of comoving metal-poor stars…
A Tilt in the Dark Matter Halo of the Galaxy
Jiwon Jesse Han, Rohan P. Naidu, Charlie Conroy +9
Recent observations of the stellar halo have uncovered the debris of an ancient merger, Gaia-Sausage-Enceladus, estimated to have occurred ~8 Gyr ago. Follow-up studies have associ…
The Age-Metallicity-Specific Orbital Energy Relation for the Milky Way's Globular Cluster System Confirms the Importance of Accretion for Its Formation
Turner Woody, Kevin C. Schlaufman
Globular clusters can form inside their host galaxies at high redshift when gas densities were higher and gas-rich mergers were common. They can also form inside lower-mass galaxie…
