Spectroscopic Follow-up of Young High- Dwarf Star Candidates: Still Likely Genuinely Young
Yuxi Lu, Catherine Manea, Maryum Sayeed +9
The question of whether genuinely young high- stars exist has been discussed for over a decade since their discovery from asteroseismology of giant stars as it is challenging to…
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…
Exploring the History of Stellar Mergers with Chemistry: Examining the Origins of Massive -Enriched Stars using Carbon Isotope Ratios
Zachary G. Maas, Keith Hawkins, Jeffrey M. Gerber +2
Recently discovered massive -enriched (MAE) stars have surface chemistry consistent with members of the older thick disk Milky Way population but high masses ( 1.5 - 3 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…
