cds-question@unistra.freclipsing-binary-starsvisible-astronomybroad-band-photometryradial-velocityccd-photometryV335 Ser is now known to be an eccentric double-lined A1+A3 binary star with fairly deep (0.5mag) partial eclipses. Previous studies of the system are improved with 7456 differential photometric observations from the URSA WebScope and 5666 from the NFO WebScope, and 67 high-resolution spectroscopic observations from the Tennessee State University 2m automatic spectroscopic telescope. From dates of minima, the apsidal period is about 880 years. Accurate (better than 2%) masses and radii are determined from analysis of the two new light curves and the radial velocity curve. Theoretical models match the absolute properties of the stars at an age of about 380Myr, though the age agreement for the two components is poor. Tidal theory correctly confirms that the orbit should still be eccentric, but we find that standard tidal theory is unable to match the observed asynchronous rotation rates of the components' surface layers.2012AJ....144...63Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/144/63CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2012)B/sb9 : 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-2013)III/249 : Stellar radial velocities bibliographic catalog (Malaroda+, 2006)J/AJ/143/129 : BF Dra photometric & spectroscopic obs.
