Variability among stars in the M 67 field from Kepler/K2-Campaign-5 light curves.

GONZALEZ G.

Abstract (from CDS):

We examine the photometric variability of stars in the M 67 field using Kepler/K2-Campaign-5 light curves. Variabilities and periods were determined for 639 stars. The mean photometric period of 28 single Sun-like members stars in M 67 is 23.4±1.2 d. This corresponds to a gyro-age of 3.7±0.3 Gyr, assuming the periods can be associated with rotation. The intrinsic variabilities of the solar analogues are greater than the Sun's variability, as measure from VIRGO fluxes. We also find evidence that the single cluster members have a different distribution of variability than the binary members.
