cds-question@unistra.frmultiple-starsproper-motionsphotometryIn a search of proper motion catalogs for common proper motion stars in the field of the Kepler spacecraft I identified 93 likely binary systems. A comparison of their rotation periods is a test of the gyrochronology concept. To find their periods I calculated the autocorrelation function (ACF) of the Kepler mission photometry for each star. In most systems for which good periods can be found, the cooler star has a longer period than the hotter component, in general agreement with models. However, there is a wide range in the gradients of lines connecting binary pairs in a period-color diagram. Furthermore, near the solar color, only a few stars have longer periods than the Sun, suggesting that they, and their cooler companions, are not much older than the Sun. In addition, there is an apparent gap at intermediate periods in the period distribution of the late K and early M stars. Either star formation in this direction has been variable, or stars evolve in period at a non-uniform rate, or some stars evolve more rapidly than others at the same mass. Finally, using the ACF as a measure of the activity level, I found that while the F, G, and early K stars become less active as their periods increase, there is no correlation between period and activity for the mid K to early M stars.2017ApJ...835...75Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/835/75CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)I/329 : URAT1 Catalog (Zacharias+ 2015)I/322 : UCAC4 Catalogue (Zacharias+, 2012)I/317 : The PPMXL Catalog (Roeser+ 2010)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)I/259 : The Tycho-2 Catalogue (Hog+ 2000)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)J/ApJ/821/93 : Rotation + Galactic kinematics of mid M dwarfs (Newton+, 2016)J/MNRAS/455/4212 : Pan-STARRS 1: occurrence in the Kepler field (Dacon+, 2016)J/AJ/151/68 : Kepler Mission.
