An Analytic Model for Stellar Metallicity Gradient Residuals in Cold, Phase-Mixed Galactic Disks

Shaunak Modak, Zoe Hackshaw, Keith Hawkins

The distribution of stellar metallicities over phase space in galactic disks is sculpted by both star formation and secular orbital transport processes. As a result, chemo-dynamica…

Dynamical Origins of Azimuthal Metallicity Variations in the Galactic Disk: Insights from Kinematic Ridges with Gaia

Carlos Jurado, Keith Hawkins, Jason A. S. Hunt +4

Kinematic and spectroscopic studies in the past few years have revealed coherent azimuthal metallicity variations across the Milky Way's disk that may be the result of dynamical pr…

A Detailed Chemical Analysis of the Red Giant Orbiting the Black Hole BH3: From Lithium to Thorium

Zoe Hackshaw, Keith Hawkins, Catherine Manea

Preliminary astrometric data from the fourth data release of the mission revealed a 33 M dark companion to a metal-poor red giant star, deemed BH3. This sys…

[X/Fe] Marks the Spot: Mapping Chemical Azimuthal Variations in the Galactic Disk with APOGEE

Zoe Hackshaw, Keith Hawkins, Carrie Filion +4

Chemical cartography of the Galactic disk provides insights to its structure and assembly history over cosmic time. In this work, we use chemical cartography to explore chemical gr…
