Towards precise stellar ages: combining isochrone fitting with empirical gyrochronology
Ruth Angus, Timothy D. Morton, Daniel Foreman-Mackey +7
We present a new age-dating technique that combines gyrochronology with isochrone fitting to infer ages for FGKM main-sequence and subgiant field stars. Gyrochronology and isochron…
K2 rotation periods for low-mass Hyads and a quantitative comparison of the distribution of slow rotators in the Hyades and Praesepe
S. T. Douglas, J. L. Curtis, M. A. Agüeros +4
We analyze K2 light curves for 132 low-mass (~) members of the 600--800~Myr-old Hyades cluster and measure rotation periods ()…
The Mass of the White Dwarf Companion in the Self-Lensing Binary KOI-3278: Einstein vs. Newton
Daniel A. Yahalomi, Yossi Shvartzvald, Eric Agol +10
KOI-3278 is a self-lensing stellar binary consisting of a white-dwarf secondary orbiting a Sun-like primary star. Kruse and Agol (2014) noticed small periodic brightenings every 88…
Benchmarking Substellar Evolutionary Models Using New Age Estimates for HD 4747 B and HD 19467 B
Charlotte M. Wood, Tabetha Boyajian, Kaspar von Braun +5
Constraining substellar evolutionary models (SSEMs) is particularly difficult due to a degeneracy between the mass, age, and luminosity of a brown dwarf. In cases where a brown dwa…
