Metallicities of Outer Halo M31 Globular Clusters from Integrated Light Calcium-II Triplet Spectroscopy
Charli Sakari, George Wallerstein
This paper presents [Fe/H] ratios for GCs in the outer halo of the Andromeda Galaxy, M31, based on moderate-resolution, integrated light (IL) spectroscopy of the calcium-II triplet…
S stars and s-process in the Gaia era II. Constraining the luminosity of the third dredge-up with Tc-rich S stars
Shreeya Shetye, Sophie Van Eck, Alain Jorissen +6
S stars are late-type giants that are transition objects between M-type stars and carbon stars on the asymptotic giant branch (AGB). They are classified into two types: intrinsic o…
The Massive M31 Cluster G1: Detailed Chemical Abundances from Integrated Light Spectroscopy
Charli M. Sakari, Matthew D. Shetrone, Andrew McWilliam +1
G1, also known as Mayall II, is one of the most massive star clusters in M31. Its mass, ellipticity, and location in the outer halo make it a compelling candidate for a former nucl…
Physical Conditions in Shocked Interstellar Gas Interacting with the Supernova Remnant IC 443
Adam M. Ritchey, Edward B. Jenkins, Steven R. Federman +3
We present the results of a detailed investigation into the physical conditions in interstellar material interacting with the supernova remnant IC 443. Our analysis is based on a c…
The M dwarf problem: Fe and Ti abundances in a volume-limited sample of M dwarf stars
Vincent M. Woolf, George Wallerstein
We report iron and titanium abundance measurements from high resolution spectra in a volume-limited sample of 106 M0 and M0.5 dwarf stars. The sample includes stars north of the ce…
The R-Process Alliance: Discovery of a low-alpha, r-Process-Enhanced Metal-Poor Star in the Galactic Halo
Charli M. Sakari, Ian U. Roederer, Vinicius M. Placco +24
A new moderately r-process-enhanced metal-poor star, RAVE J093730.5-062655, has been identified in the Milky Way halo as part of an ongoing survey by the R-Process Alliance. The te…
