HARPS Abundances with Korg I: 22 Element Abundances for 426 Red Giant Stars
Sarah E. Aquilina, Melissa Ness, Adam J. Wheeler +1
Large stellar surveys have revealed the global abundance structure of the Milky Way, but small high-fidelity spectral samples offer a critical complement of nucleosynthetic depth.…
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…
Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217
The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…
ACACIAS I: Element abundance labels for 192 stars in the dwarf galaxy NGC 6822
Melissa K. Ness, J. Trevor Mendel, Sven Buder +8
The element abundances of local group galaxies connect enrichment mechanisms to galactic properties and serve to contextualise the Milky Way's abundance distributions. Individual s…
Weighing The Options: The Unseen Companion in LAMOST J2354 is Likely a Massive White Dwarf
M. A. Tucker, A. J. Wheeler, D. M. Rowan +1
LAMOST J235456.73+335625 (J2354) is a binary system hosting a K dwarf and a dark companion, supposedly a neutron star, in a 0.48d orbi…
