Machine Learning Techniques to Distinguish Giant Stars from Dwarf Stars Using Only Photometry -- Pushing Redwards
Keyi Ding, Carrie Filion, Rosemary F. G. Wyse +6
We present our photometric method, which combines Subaru/HSC , g, and i band filters to distinguish giant stars in Local Group galaxies from Milky Way dwarf contamination. T…
On the connection between nitrogen-enhanced field stars and the Galactic globular clusters
Sarah G. Kane, Vasily Belokurov, Stephanie Monty +6
As sites of some of the most efficient star formation in the Universe, globular clusters (GCs) have long been hypothesized to be the building blocks of young galaxies. Within the M…
Optical Spectroscopy Reveals Hidden Neutron-capture Elemental Abundance Differences among APOGEE-identified Chemical Doppelgängers
Catherine Manea, Melissa Ness, Keith Hawkins +9
Grouping stars by chemical similarity has the potential to reveal the Milky Way's evolutionary history. The APOGEE stellar spectroscopic survey has the resolution and sensitivity f…
Counterculture Stars: Slow and Retrograde Stars with Low-Alpha Disk Abundances
Carrie Filion, Michael S. Petersen, Danny Horta +3
The Milky Way is home to a thin disk that can be defined via kinematics and/or elemental abundances. The elemental abundance-defined thin disk, also called the low-alpha disk, is g…
Secular Attrition of Classical Bulges by Stellar Bars
Rachel Lee McClure, Tobias Géron, Elena D'Onghia +5
Classical bulges and stellar bars are common features in disk galaxies and serve as key tracers of galactic evolution. Angular momentum exchange at bar resonances drives secular mo…
Constraints on asteroid-mass primordial black holes in dwarf galaxies using Hubble Space Telescope photometry
Nicolas Esser, Carrie Filion, Sven De Rijcke +4
Primordial black holes (PBHs) in the asteroid-mass range remain a viable and until now unconstrained dark matter (DM) candidate. If such PBHs exist, they could be captured by stars…
