Beginning of ReadMe : J/A+A/520/A52 31 Com radial velocities (Strassmeier+, 2010) ================================================================================ Rotation and magnetic activity of the Hertzsprung-gap giant 31 Comae. Strassmeier K.G., Granzer T., Kopf M., Weber M., Kueker M., Reegen P., Rice J.B., Matthews J.M., Kuschnig R., Rowe J.F., Guenther D.B., Moffat A.F.J., Rucinski S.M., Sasselov D., Weiss W.W. <Astron. Astrophys. 520, A52 (2010)> =2010A&A...520A..52S ================================================================================ ADC_Keywords: Stars, giant ; Radial velocities Keywords: stars: activity - stars: atmospheres - stars: individual: 31 Comae - starspots - stars: late-type - stars: rotation Abstract: The single rapidly-rotating G0 giant 31 Comae has been a puzzle because of the absence of photometric variability despite its strong chromospheric and coronal emissions. As a Hertzsprung-gap giant, it is expected to be at the stage of rearranging its moment of inertia, hence likely also its dynamo action, which could possibly be linked with its missing photospheric activity. Our aim is to detect photospheric activity, obtain the rotation period, and use it for a first Doppler image of the star's surface. Its morphology could be related to the evolutionary status. Description: We carried out high-precision, white-light photometry with the MOST satellite, ground-based Stroemgren photometry with automated telescopes, and high-resolution optical echelle spectroscopy with the new STELLA robotic facility.
