The K2 M67 study: A curiously young star in an eclipsing binary in an old open cluster
- Abstract:
-
We present an analysis of a slightly eccentric (e = 0.05), partially eclipsing, long-period (P = 69.73 days) main-sequence binary system (WOCS 12009, Sanders 1247) in the benchmark old open cluster M67. Using Kepler K2 and ground-based photometry, along with a large set of new and reanalyzed spectra, we derived highly precise masses (1.111 ± 0.015 and 0.748 ± 0.005 Mo) and radii (1.071 ± 0.008 ± 0.003 and 0.713 ± 0.019 ± 0.026 Ro, with statistical and systematic error estimates) for the stars...
