Milky Way Mapper decoded abundances -- II: From patterns to paths
Melissa K. Ness, Sarah Aquilina, Jennifer Mead +15
The element abundances of Milky Way disc stars encode entangled imprints of multiple enrichment processes, making it difficult to uncover the underlying chemical evolution. Here we…
Milky Way Mapper decoded abundances -- I. Shared disc enrichment patterns
Melissa K. Ness, Sarah Aquilina, Jennifer Mead +15
Elemental abundances in the Milky Way disc trace its star-formation and enrichment history, but predicting these abundances from theory is limited by uncertain nucleosynthetic yiel…
Hydrostatic and explosive -element chemical abundances of Milky Way globular clusters, halo substructures, and satellite galaxies
Danny Horta, Melissa K. Ness
Stellar atmospheric element abundance ratios of stars retain information about their birth conditions, helping elucidate their origin and nature. In this letter, we analyse and con…
Four Elements to Rule Them All: Abundances are Rigidly Coupled in the Milky Way Disk
Jennifer Mead, Rebeca De La Garza, Melissa Ness
Chemical tagging is a central pursuit of galactic archaeology, but requires sufficiently discriminative abundances to uniquely identify sites of star formation. This task is compli…
: A generative, multi-output, latent-variable model for astronomical data with noisy labels
Danny Horta, Adrian M. Price-Whelan, David W. Hogg +2
The large volume of spectroscopic data available now and from near-future surveys will enable high-dimensional measurements of stellar parameters and properties. Current methods fo…
Exoplanet Occurrence Rate with Age for FGK Stars in Kepler
Maryum Sayeed, Ruth Angus, Travis Berger +5
We measure exoplanet occurrence rate as a function of isochrone and gyrochronology ages using confirmed and candidate planets identified in Q1-17 DR25 Kepler data. We employ Kepler…
Evidence of Truly Young high- Dwarf Stars
Yuxi Lu, Isabel L. Colman, Maryum Sayeed +14
The existence of high- stars with inferred ages < 6 Gyr has been confirmed recently with large spectroscopic and photometric surveys. However, stellar mergers or binary interact…
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…
Stellar Mergers or Truly Young? Intermediate-Age Stars on Highly-Radial Orbits in the Milky Way's Stellar Halo
Danny Horta, Yuxi, Lu +3
Reconstructing the mass assembly history of the Milky Way relies on obtaining detailed measurements of the properties of many stars in the Galaxy, especially in the stellar halo. O…
Measuring Dwarf Galaxy Intrinsic Abundance Scatter with Mid-resolution Spectroscopic Surveys: Calibrating APOGEE Abundance Errors
Jennifer Mead, Melissa Ness, Eric Andersson +2
The first generations of stars left their chemical fingerprints on metal-poor stars in the Milky Way and its surrounding dwarf galaxies. While instantaneous and homogeneous enrichm…
