cds-question@unistra.fremission-line-starsbe-starsinfrared-photometryvisible-astronomybroad-band-photometryUBVR photometric monitoring of Herbig Ae/Be stars and some related objects has been carried out at Maidanak Observatory in Uzbekistan since 1983. More than 71,000 observations of about 230 stars have been obtained and are made available for anonymous ftp. Virtually all Herbig Ae/Be stars observed are irregular variables (called "UXors" after UX Ori), but there is a wide range of amplitudes from barely detectable to more than 4mag in V. Our data confirm the results of previous studies, which indicate that large-amplitude variability is confined to stars with spectral types later than B8. The distribution of variability ranges is quite similar to what is seen in classical T Tauri stars.1999AJ....118.1043Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/118/1043CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toftp://www.astro.wesleyan.edu/pub/ttauri : T Tauri databasehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/118/1043https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/118/1043http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/118/1043https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/118/1043https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/118/1043http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/118/1043GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/118/1043/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/118/1043/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/118/1043/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/118/1043/stars?GETtext/xml+votable180.050000true187.2779172.0522220.005555555555555556Cone search capability for table J/AJ/118/1043/tables (Summary of data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/118/1043/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/118/1043/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/118/1043/tables?GETtext/xml+votable180.050000true73.941021730.55119080.0055555555555555565/292 3842 5887 6/336 342 473 859 862 1029 1031 1040 1043 1048 1050-1052 1054 1073-1075 1081 1083 1111 1114-1115 1124 1136 1156 1159 1196 1591 2188 3005 3038 3057 3071 3839 10255 11786 12592 13110 13736 13786 13981 14031 14040 14063 14306 14311 14344 14632 14647 14685-14687 14696-14697 14700 15363 15409 15411 15682-15684 15701 15759 15798 15840 15851 16129 16131 16220-16221 19283 20286 21435-21436 21438-21439 21456 21643 21646 22707 22804-22805 22828 22851 22873 22911 23542 23636-23637 23644 23646 23683 23704 23717 23727 23736 23738-23739 23767 23798 23970 24201 24203 24277 24300 24449 26292 28890-28891 28921 29193 29201 29463 29519 29558 30242-30243 30251 30361 30363 30741 33116 36948 36956-36957 38382 42429 42605 42704 42714 42736 42970 42972 42977 42981 42989 42992 42994 44317 44378-44379 44894 47742 47828https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/118/1043?format=asciiOpticalInfrareddefaultJ/AJ/118/1043/starsList of studied starsrecnoRecord number assigned by the VizieR team.
