Rotation and H emission in a young SMC cluster: a spectroscopic view of NGC 330

Paul I. Cristofari, Andrea K. Dupree, Antonino P. Milone +4

We present an analysis of high-resolution optical spectra recorded for 30 stars of the split extended main-sequence turnoff (eMSTO) of the young ( 40 Myr) Small Magellanic Cl…

Abundances of Neutron-Capture Elements in 62 Stars in the Globular Cluster Messier 15

Jonathan Cabrera Garcia, Charli M. Sakari, Ian U. Roederer +7

M15 is a globular cluster with a known spread in neutron-capture elements. This paper presents abundances of neutron-capture elements for 62 stars in M15. Spectra were obtained wit…

Magellan/M2FS and MMT/Hectochelle Spectroscopy of Dwarf Galaxies and Faint Star Clusters within the Galactic Halo

Matthew G. Walker, Nelson Caldwell, Mario Mateo +5

We present spectroscopic data for 16369 stellar targets within and/or toward 38 dwarf spheroidal galaxies and faint star clusters within the Milky Way halo environment. All spectra…

SCExAO and Keck Direct Imaging Discovery of a Low-Mass Companion Around the Accelerating F5 Star HIP 5319

Noah Swimmer, Thayne Currie, Sarah Steiger +26

We present the direct imaging discovery of a low-mass companion to the nearby accelerating F star, HIP 5319, using SCExAO coupled with the CHARIS, VAMPIRES, and MEC instruments in…
