cds-question@unistra.frspectroscopic-binary-starsx-ray-binary-starsradial-velocityline-intensitiesWe present results from an H{alpha} monitoring campaign of the Be X-ray binary systems HDE 245770 = A0535+26 and X Per. We use the H{alpha} equivalent widths together with adopted values of the Be star effective temperature, disk inclination, and disk outer boundary to determine the half-maximum emission radius of the disk as a function of time.2007ApJ...660.1398Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/660/1398CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/656/431 : LS I +65 010 radial velocities & Halpha EW (Grundstrom+, 2007)J/ApJ/656/437 : LS I +61 303 radial velocities & Halpha EW (Grundstrom+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/660/1398https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/660/1398http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/660/1398https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/660/1398https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/660/1398http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/660/1398GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/660/1398/table3X Per IUE radial velocity measurementsrecnoRecord number assigned by the VizieR team.
