A catalogue of eclipsing variables
A new catalogue of 6330 eclipsing variable stars is presented. Thecatalogue was developed from the General Catalogue of Variable Stars(GCVS) and its textual remarks by including recently publishedinformation about classification of 843 systems and making correspondingcorrections of GCVS data. The catalogue1 represents thelargest list of eclipsing binaries classified from observations.
| Absolute dimensions of solar-type eclipsing binaries. I. uvby light curves for HS Aqr, KX Aqr, AL Ari, V963 Cen, MR Del, NY Hya, DU Leo, UW LMi, and V358 Pup
We present complete uvby light curves of 9 recently discovered eclipsingbinaries having late F, G, and K type components within or near themain-sequence band. They are the first results from a long term programcarried out since 1994 at the Strömgren Automatic Telescope at ESO,La Silla. The aim is to provide the accurate absolute dimensions forsolar-type stars needed for critical tests of the correspondingtheoretical models. A serious dilemma appears to be present in thecomparison of predictions from current stellar models with fundamentalproperties of known 0.7-1.1 Msun eclipsing binaries (Popper\cite{dmp97b}, Clausen et al. \cite{granada99b}). Spectroscopicobservations of the 9 eclipsing binaries are either available or arebeing obtained, and detailed analyses of the individual systems will bepublished in a series of subsequent papers. The light curves wereobtained as part of a systematic search for new eclipsing systems amonga large sample of (mostly) spectroscopic binaries. Catalogues of theextensive uvby and beta photometry from this search will be publishedseparately. Based on observations carried out with the StrömgrenAutomatic Telescope (SAT) at ESO, La Silla, Chile. When the individualanalyses are finished, Tables 12-20 will gradually be made available inelectronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr(130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/374/980
| Two-colour photometry for 9473 components of close Hipparcos double and multiple stars
Using observations obtained with the Tycho instrument of the ESAHipparcos satellite, a two-colour photometry is produced for componentsof more than 7 000 Hipparcos double and multiple stars with angularseparations 0.1 to 2.5 arcsec. We publish 9473 components of 5173systems with separations above 0.3 arcsec. The majority of them did nothave Tycho photometry in the Hipparcos catalogue. The magnitudes arederived in the Tycho B_T and V_T passbands, similar to the Johnsonpassbands. Photometrically resolved components of the binaries withstatistically significant trigonometric parallaxes can be put on an HRdiagram, the majority of them for the first time. Based on observationsmade with the ESA Hipparcos satellite.
