The large-scale kinematics of young stars in the Milky Way disc: first results from SDSS-V
Eleonora Zari, Jaime Villaseñor, Marina Kounkel +17
We present a first large-scale kinematic map of 50,000 young OB stars ( K), based on BOSS spectroscopy from the Milky Way Mapper OB program in the on…
The formation and survival of the Milky Way's oldest stellar disk
Maosheng Xiang, Hans-Walter Rix, Hang Yang +3
It remains a mystery when our Milky Way first formed a stellar disk component that survived and maintained its disk structure from subsequent galaxy mergers. We present a study of…
The Age-Dependent Vertical Actions of Young Stars in the Galaxy
D. N. Garzon, Neige Frankel, Eleonora Zari +2
Stars in the Galactic disk are born on cold, nearly circular orbits with small vertical excursions. After their birth, their orbits evolve, driven by small- or large-scale perturba…
Iron Snails: non-equilibrium dynamics and spiral abundance patterns
Neige Frankel, David W. Hogg, Scott Tremaine +2
Galaxies are not in a dynamical steady state. They continually undergo perturbations, e.g., from infalling dwarf galaxies and dark-matter substructure. After a dynamical perturbati…
The Extremely Metal Rich Knot of Stars at the Heart of the Galaxy
Hans-Walter Rix, Vedant Chandra, Gail Zasowski +15
We show with Gaia XP spectroscopy that extremely metal-rich stars in the Milky Way (EMR; ) - but only those - are largely confined to a tight "knot" at the center…
What Does the Large Magellanic Cloud Look Like? It Depends on [M/H] and Age
Neige Frankel, Rene Andrae, Hans-Walter Rix +2
We offer a new way to look at the Large Magellanic Cloud through stellar mono-abundance and mono-age-mono-abundance maps. These maps are based on member stars wi…
A comparison of the Milky Way's recent star formation revealed by dust thermal emission and high-mass stars
J. D. Soler, E. Zari, D. Elia +10
We present a comparison of the Milky Way's star formation rate (SFR) surface density () obtained with two independent state-of-the-art observational methods. The first…
Decoding the age-chemical structure of the Milky Way disk: An application of Copulas and Elicitable Maps
Aarya A. Patil, Jo Bovy, Sebastian Jaimungal +2
In the Milky Way, the distribution of stars in the vs. and vs. age planes holds essential information about the history of sta…
Disk flaring with TNG50: diversity across Milky Way and M31 analogs
Diego Sotillo-Ramos, Martina Donnari, Annalisa Pillepich +4
We use the sample of 198 Milky Way (MW) and Andromeda (M31) analogs from TNG50 to quantify the level of disk flaring predicted by a modern, high-resolution cosmological hydrodynami…
The Origin of Stars in the Inner 500 Parsecs in TNG50 Galaxies
Alina Boecker, Nadine Neumayer, Annalisa Pillepich +4
We investigate the origin of stars in the innermost of galaxies spanning stellar masses of at using the cos…
Vertical motion in the Galactic disc: unwinding the Snail
Neige Frankel, Jo Bovy, Scott Tremaine +1
The distribution of stars in the Milky Way disc shows a spiral structure--the Snail--in the space of velocity and position normal to the Galactic mid-plane. The Snail appears as st…
The origin and fate of the Gaia phase-space snail
Scott Tremaine, Neige Frankel, Jo Bovy
The Gaia snail is a spiral feature in the distribution of solar-neighbourhood stars in position and velocity normal to the Galactic midplane. The snail probably arises from phase m…
High-contrast, high-angular resolution view of the GJ 367 exoplanet system
Wolfgang Brandner, Per Calissendorff, Neige Frankel +1
We search for additional companions in the GJ 367 exoplanet system, and aim at better constraining its age and evolutionary status. We analyse high contrast direct imaging observat…
Simulated Bars May Be Shorter But Are Not Slower Than Observed: TNG50 vs. MaNGA
Neige Frankel, Annalisa Pillepich, Hans-Walter Rix +6
Galactic bars are prominent dynamical structures within disk galaxies whose size, formation time, strength, and pattern speed influence the dynamical evolution of their hosts galax…
Gravitational wave sources in our Galactic backyard: Predictions for BHBH, BHNS and NSNS binaries detectable with LISA
Tom Wagg, Floor S. Broekgaarden, Selma E. de Mink +3
Future searches for gravitational waves from space will be sensitive to double compact objects (DCOs) in our Milky Way. We present new simulations of the populations of double blac…
Mapping Luminous Hot Stars in the Galaxy
E. Zari, H. -W. Rix, N. Frankel +4
[Abridged] Luminous hot stars dominate the stellar energy input to the interstellar medium throughout cosmological time, they are laboratories to test theories of stellar evolution…
Orbital and spectral characterization of the benchmark T-type brown dwarf HD 19467B
A. -L. Maire, K. Molaverdikhani, S. Desidera +42
Context. Detecting and characterizing substellar companions for which the luminosity, mass, and age can be determined independently is of utter importance to test and calibrate the…
The Strength of the Dynamical Spiral Perturbation in the Galactic Disk
Anna-Christina Eilers, David W. Hogg, Hans-Walter Rix +4
The mean Galactocentric radial velocities of luminous red giant stars within the mid-plane of the Milky Way reveal a spiral signature, which could plaus…
Keeping it Cool: Much Orbit Migration, yet Little Heating, in the Galactic Disk
Neige Frankel, Jason Sanders, Yuan-Sen Ting +1
A star in the Milky Way's disk can now be at a Galactocentric radius quite distant from its birth radius for two reasons: either its orbit has become eccentric through radial heati…
The Inside-out Growth of the Galactic Disk
Neige Frankel, Jason Sanders, Hans-Walter Rix +2
We quantify the inside-out growth of the Milky Way's low-alpha stellar disk, modelling the ages, metallicities and Galactocentric radii of APOGEE red clump stars with 6 < R < 13 kp…
Spatial variations in the Milky Way disc metallicity-age relation
Diane K. Feuillet, Neige Frankel, Karin Lind +5
Stellar ages are a crucial component to studying the evolution of the Milky Way. Using Gaia DR2 distance estimates, it is now possible to estimate stellar ages for a larger volume…
Measuring Radial Orbit Migration in the Milky Way Disk
Neige Frankel, Hans-Walter Rix, Yuan-Sen Ting +2
We develop and apply a model to quantify the global efficiency of radial orbit migration among stars in the Milky Way disk. This model parameterizes the possible star formation and…
