Revealing the Field Sub-subgiant Population Using a Catalog of Active Giant Stars and Gaia EDR3
Emily M. Leiner, Aaron M. Geller, Michael A. Gully-Santiago +2
Sub-subgiant stars (SSGs) fall below the subgiant branch and/or red of the giant branch in open and globular clusters, an area of the color-magnitude diagram (CMD) not populated by…
Observationally Constraining the Starspot Properties of Magnetically Active M67 Sub-Subgiant S1063
Natalie M. Gosnell, Michael A. Gully-Santiago, Emily M. Leiner +1
Our understanding of the impact of magnetic activity on stellar evolution continues to unfold. This impact is seen in sub-subgiant stars, defined to be stars that sit below the sub…
A Census of Blue Stragglers in Gaia DR2 Open Clusters as a Test of Population Synthesis and Mass Transfer Physics
Emily M. Leiner, Aaron Geller
We use photometry and proper motions from Gaia DR2 to determine the blue straggler star (BSS) populations of 16 old (1-10 Gyr), nearby ( pc) open clusters. We find that th…
Stellar Radial Velocities in the Old Open Cluster M67 (NGC 2682). II. The Spectroscopic Binary Population
Aaron M. Geller, Robert D. Mathieu, David W. Latham +3
We present and analyse 120 spectroscopic binary and triple cluster members of the old (4 Gyr) open cluster M67 (NGC 2682). As a cornerstone of stellar astrophysics, M67 is a key cl…
