The Chemical Homogeneity of Single-Lined Spectroscopic Binaries in Open Clusters
Amaya Sinha, Gail Zasowski, Natalie R. Myers +16
Using SDSS-V DR19 Milky Way Mapper APOGEE data, we measure the impact that close binarity has on surface chemistry across the Hertzsprung-Russell diagram in a broad set of abundanc…

Wide binaries without viable bound Newtonian orbits
L. Pasquini, R. Saglia, F. Patat +7
Context. Wide binaries offer a unique opportunity to test gravity in the low acceleration regime, where deviations from Newtonian dynamics may appear. Aims. We use high-resolution…
