cds-question@unistra.freclipsing-binary-starsvilnius-photometryNew photometric observations of the Wolf-Rayet binary HD 211853 are presented. They were obtained with the 1-m reflector of the Institute of Theretical Physics and Astrophysics of the Lithuanian Academy of Sciences on Maydanak Mountain in Uzbekistan during 15 nights in August 1991; a single-channel photometer equipped with the Vilius photometric system filters was used. The period search routine confirms the period of 6.6884 days for pair A. For pair B, a new corrected ephemeris (T0 = 2443689.16, P = 3.4696 days) is determined. This ephemeris allows to present light minima of all available photometric data in the same phase. Moreover, they are in good accordance with the absorption lines radial velocity residuals of Hiltner (1945ApJ...101..356H) and Massey (1981ApJ...244..157M). It is shown that the third possible period of 2.34607 days found by Panov & Seggewiss (1990A&A...227..117P) is an alias from the half period of approximately 3.47 days.1994A&A...282..137Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/282/137CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/282/137https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/282/137http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/282/137https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/282/137https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/282/137http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/282/137GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/282/137/table2Photometric observations of HD211853 relative to the comparison starrecnoRecord number assigned by the VizieR team.
