cds-question@unistra.freclipsing-binary-starsvisible-astronomybroad-band-photometryWe present the results of a systematic search for pulsating components in Algol-type eclipsing binary systems. A total number of 14 eclipsing binaries with A-F spectral type primary components were observed for 22 nights. We confirmed small-amplitude oscillating features of a recently detected pulsator TW Dra, which has a pulsating period of 0.053-day and a semi-amplitude of about 5-mmag in B-passband. We discovered new pulsating components in two eclipsing binaries of RX Hya and AB Per. The primary component of RX Hya is pulsating with a dominant period of 0.052-day and a semi-amplitude of about 7-mmag. AB Per has also a pulsating component with a period of 0.196-day and a semi-amplitude of about 10-mmag in B-passband. We suggest that these two new pulsators are members of the newly introduced group of mass-accreting pulsating stars in semi-detached Algol-type eclipsing binary systems.2003A&A...405..231Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/405/231CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/46 : Classical (Evolved) Algol-Type Binary Candidates (Budding 1984)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/405/231https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/405/231http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/405/231https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/405/231https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/405/231http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/405/231GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/405/231/stars (Star positions and magnitudes (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/405/231/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/405/231/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/405/231/stars?GETtext/xml+votable180.050000true233.46291763.9072220.0055555555555555566/1020 1213 1628 1684 2119 2508 3953 3956 4484 7233 7422 7637 9044 11657 11659 40900https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/405/231?format=asciiOpticaldefaultJ/A+A/405/231/starsStar positions and magnitudes (from Simbad)recnoRecord number assigned by the VizieR team.
