The Tale of a Hungry Subgiant and Its Brown Dwarf: Interior Radiative Damping Dominates the Tidal Evolution of TOI-5882
Ritvik Sai Narayan, Melinda Soares-Furtado, Richard H. D. Townsend
We present a self-consistent tidal evolution framework that couples binary evolution from MESA to the full linear tidal response from GYRE-tides. Applying this framework to TOI-588…
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…
Twinkle Twinkle Little Star, Roman Sees Where You Are: Predicting Exoplanet Transit Yields in the Rosette Nebula with the Nancy Grace Roman Space Telescope
Ritvik Sai Narayan, Melinda Soares-Furtado, Mary Anne Limbach +3
Young stars host only a small fraction of the known exoplanet population because their photometric variability, magnetic activity, and frequent placement in dense, poorly-resolved…
TESS Hunt for Young and Maturing Exoplanets (THYME) XIV: A Comoving-Based Age Constraint for KELT-20
Adam Distler, Melinda Soares-Furtado, Andrew W. Mann +9
Young stellar moving groups offer unique opportunities to investigate the early evolution of stellar and planetary systems. In continuation of an ongoing effort to age-date compell…
A Multi-Method Age Determination for the Ursa Major Moving Group
Julia Sheffler, Max Clark, Melinda Soares-Furtado +4
The Ursa Major Moving Group (UMa) is one of the closest stellar associations, yet its age has remained controversial, with published estimates ranging from 200 Myr to 1 Gyr. We pre…
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…
