GJ 523b is a Massive, 170 Myr-old Mega-Earth, Likely on a Polar Orbit
Maxwell A. Kroft, Thomas G. Beatty, Joseph M. Salzer +18
We use WIYN/NEID radial velocity measurements to confirm the planetary nature and measure the mass of the TESS transiting exoplanet candidate around the mid-K dwarf GJ 523 ($V=9.23…
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…
