cds-question@unistra.freclipsing-binary-starsam-starsradial-velocityAccurate physical properties of eclipsing stars provide important constraints on models of stellar structure and evolution, especially when combined with spectroscopic information on their chemical composition. Empirical calibrations of the data also lead to accurate mass and radius estimates for exoplanet host stars. Finally, accurate data for unusual stellar subtypes, such as Am stars, also help to unravel the cause(s) of their peculiarities. We aim to determine the masses, radii, effective temperatures, detailed chemical composition and rotational speeds for the Am-type eclipsing binaries SWCMa (A4-5m) and HWCMa (A6m) and compare them with similar normal stars.2012A&A...537A.117Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/537/A117CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/487/1081 : uvby phot. of HW CMa & 5 eclipsing binaries (Clausen+, 2008)J/A+A/461/1077 : Radial velocities of DW Car (Southworth+, 2007)J/A+A/469/285 : Differential Stroemgren photometry of U Oph (Vaz+, 2007)J/A+A/487/1095 : Radial velocities of AD Boo, VZ Hya, WZ Oph (Clausen+, 2008)J/A+A/516/A42 : Spectral lines of BK Peg and BW Aqr (Clausen+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/537/A117https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/537/A117http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/537/A117https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/537/A117https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/537/A117http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/537/A117GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/537/A117/stars (Observed stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/537/A117/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/537/A117/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/537/A117/stars?GETtext/xml+votable180.050000true107.063333-22.4402780.0055555555555555566/20803https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/537/A117?format=asciiOpticaldefaultJ/A+A/537/A117/starsObserved starsrecnoRecord number assigned by the VizieR team.
