cds-question@unistra.freclipsing-binary-starsWe present an analysis of the apsidal motion and light curve parameters of 54 never-before-studied galactic Algol-type binaries. This is the first analysis of such a large sample of eccentric eclipsing binaries in our Galaxy, and has enabled us to identify several systems that are worthy of further study. Bringing together data from various databases and surveys, supplemented with new observations, we have been able to trace the long-term evolution of the eccentric orbit over durations extending back up to several decades. Our present study explores a rather different sample of stars to those presented in the previously published catalogue of eccentric eclipsing binaries, sampling to fainter magnitudes, covering later spectral types, sensitive to different orbital periods with more than 50% of our systems having periods longer than six days. The typical apsidal motion in the sample is rather slow (mostly of order of centuries long), although in some cases this is less than 50yr. All of the systems, except one, have eccentricities less than 0.5, with an average value of 0.23. Several of the stars also show evidence for additional period variability. In particular we can identify three systems in the sample, HD 44093, V611 Pup, and HD 313631, which likely represent relativistic apsidal rotators.2018A&A...619A..85Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/619/A85CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/619/A85https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/619/A85http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/619/A85https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/619/A85https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/619/A85http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/619/A85GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/619/A85/tablea1 (Relevant information for the analysed systems)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/619/A85/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/619/A85/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/619/A85/tablea1?GETtext/xml+votable180.050000true23.7247083367.63750.0055555555555555566/510 1749 1876 1878 1988 3225 3229 3252 3290 3573 3600 3691 7945 12792 13679 13859 14410 15565 15813 19096 20511 21736 22016 22282 23573 23762 24476-24478 28679 28912 29268 29646 32152 33072 37255 37923 38056 38184 39219 39265 39383 39411 40634 41111 41450 42122 42337 42423 42476 47339 47855 48815https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/619/A85?format=asciidefaultJ/A+A/619/A85/tablea1Relevant information for the analysed systemsSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
