WIYN Open Cluster Study. XCVII. An Extended Radial-Velocity Survey and Spectroscopic Binary Orbits in the Open Cluster NGC 188

Ritvik Sai Narayan, Evan Linck, Robert D. Mathieu +1

We present 35 new spectroscopic-binary orbits from our extended radial-velocity (RV) survey of the old ( Gyr) open cluster NGC 188. Using data from the WIYN Open Clust…

Goodbye to Chi-by-Eye: A Bayesian Analysis of Photometric Binaries in Six Open Clusters

Anna C. Childs, Aaron M. Geller, Ted von Hippel +2

We present a robust methodology for identifying photometric binaries in star clusters. Using Gaia DR3, Pan-STARRS and 2MASS data, we self-consistently define the cluster parameters…

Investigating Mass Segregation of the Binary Stars in the Open Cluster NGC 6819

Claire Zwicker, Aaron M. Geller, Anna C. Childs +2

We search for mass segregation in the intermediate-aged open cluster NGC 6819 within a carefully identified sample of probable cluster members. Using photometry from the Gaia, 2MAS…

Tracing the Origins of Mass Segregation in M35: Evidence for Primordially Segregated Binaries

Erin Motherway, Aaron M. Geller, Anna C. Childs +2

M35 is a young open cluster and home to an extensive binary population. Using Gaia DR3, Pan-STARRS, and 2MASS photometry with the Bayesian statistical software, BASE-9, we derive p…

Globular Cluster UVIT legacy Survey (GlobUleS) III. Omega Centauri in Far-Ultraviolet

Deepthi S. Prabhu, Annapurni Subramaniam, Snehalata Sahu +21

We present the first comprehensive study of the most massive globular cluster Omega Centauri in the far-ultraviolet (FUV) extending from the center to ~ 28% of the tidal radius usi…

Age and helium content of the open cluster NGC 6791 from multiple eclipsing binary members. III. Constraints from a subgiant

K. Brogaard, F. Grundahl, E. L. Sandquist +18

Models of stellar structure and evolution can be constrained using accurate measurements of the parameters of eclipsing binary members of open clusters. Multiple binary stars provi…
