cds-question@unistra.frg-starsmultiple-starsThe solar analogues 16 Cyg A and B are excellent asteroseismic targets in the Kepler field of view and together with a red dwarf and a Jovian planet form an interesting system. For these more evolved Sun-like stars we cannot detect surface rotation with the current Kepler data but instead use the technique of asteroseismology to determine rotational properties of both 16 Cyg A and B. We find the rotation periods to be 23.8^1.5^_-1.8_ and 23.2^11.5^_-3.2_ d, and the angles of inclination to be 56^6^_-5_ {deg} and 36^17^_-7_ {deg}, for A and B, respectively. Together with these results we use the published mass and age to suggest that, under the assumption of a solar-like rotation profile, 16 Cyg A could be used when calibrating gyrochronology relations. In addition, we discuss the known 16 Cyg B star-planet eccentricity and measured low obliquity which is consistent with Kozai cycling and tidal theory.2015MNRAS.446.2959Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/446/2959CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/737/L32 : Abundances of 16 Cyg A and B (Schuler+, 2011)J/ApJ/790/L23 : Solar analogs and twins rotation by Keplerhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/446/2959https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/446/2959http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/446/2959https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/446/2959https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/446/2959http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/446/2959GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/446/2959/tables12Mode frequencies for 16 Cyg A (tables1) and 16 Cyg B (tables2) with 68% credible regionsrecnoRecord number assigned by the VizieR team.
