cds-question@unistra.frdwarf-starsmagnetic-fieldsSome stars show periodic variability of the longitudinal (effective) global magnetic field B_e_ mainly due to rotation. We present the second version of the catalog of average magnetic phase curves, which are functions of B_e_ versus the rotational phase phi, tables of their parameters. The curves were obtained from literary data and as the result of observations from SAO RAS telescopes. A total of 357 stars of various spectral types were studied, data on which was published before the end of August 2020. Magnetic Ap and Bp stars make up the most numerous a subset in the catalog (224 objects). Phase curves were obtained by least squares fit of a simple sine wave or a double sine wave to the available B_e measurements. For some stars we also improved or determined periods of their rotation. Phase curves also are presented in 514 figures. In some cases several phase curves presented here correspond to the same star. This occurred when different observational techniques produced significantly different series of B_e_ values for that star. In a few cases the rotational phase curves of the surface field, B_s_, are given for stars where longitudinal magnetic field data were not available.2021A&A...652A..31Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/652/A31CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/123/353 : Mean magnetic field modulus of Ap stars (Mathys, 1997)J/A+A/407/631 : Catalogue of stellar effective magnetic fields (Bychkov+ 2003)J/A+A/430/1143 : Stellar magnetic rotational phase curves (Bychkov+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/652/A31https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/652/A31http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/652/A31https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/652/A31https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/652/A31http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/652/A31GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/652/A31/tablea1 (List of stars in the catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/652/A31/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/652/A31/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/652/A31/tablea1?GETtext/xml+votable180.050000true1.514121163.67965860.005555555555555556Cone search capability for table J/A+A/652/A31/tablea6 (Measurements for 13 stars in Orion OB1 by EF Borra (unpublished))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/652/A31/tablea6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/652/A31/tablea6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/652/A31/tablea6?GETtext/xml+votable180.050000true80.95982972.08217360.0055555555555555566/263 341 351 666 842 915 962 1029 1125 1164 1168-1169 1171 1287 1313 1506 1539 1608 1768 1848 2395 2411 2490 2664 2677 2682 2818 2970 3030 3066 3188 3266 3571 3591 3678 3694 3705 3715 3737 4095 4251 4890 5000 5501 5534 5805 6219 6229 6497 6672 6759 6995 7527 7705 7734 8291 8430 8440 8462 8627 8790 8843 9048 9847 10000 10142 10151 10255 10287 10407 10783 10791 11057 11094 11202 11279 11786 11856 12396 12592 12766 12983 13301 13557 14055 14162 14238 14272 14278 14305 14376 14405 14443 14513 14534 14567 14631-14632 14690 14718 14772 14824 14843 14855 14906 14922 15223 15361 15367 15424 15523 15850 15960 16104-16105 16131 16144 16186 16834 16982 17571 17754 17888 18067 18086 18273 18797 19064 19676 19757 20071 20286 20322 20340 20459-20460 20764 20782 20797 20834 20915 21433 21436-21437 21439-21440 21655 21696 21997 22020 22056 22071 22251 22253 22289 22615 22727 22753 22769 22772 22790 22805 22807 22815 22831 22836-22837 22849-22850 22854 22859 22861 22863 22867 22884 22887 22892-22894 22907 22911 22964 22981 23200 23255 23547 23556 23572 23611 23637 23641 23782 23860 23945 23959 24108 24562 24608 24621 24925 25516 25939 25964 26057 26092 26174 26279 26299 26353 26381 26555 26691 26699 26763 26855 26886 26997 27541 27762 28035 28137 28142 28151 28341 28688 28806 28913 29081 29138 29161 29458 29729 30083 30093 30188 30302 30434 30438 30505 30563 30698 30818 30833 31063 31330 31511 31710 31716 31744 31814 31940 32193 32198 32297 32816 32930 33717 34875 35226 35676 35756 36119 36121 36298 36341 36526 36563 36956 37181 37230-37231 37790 37814 37856 37897 37916 37932 38016 38024 38174 38287 38441 38551 39008 39085 39183 39193 39202 39205 39290 39515 39716 39776 39793 39877 40068 40783 40882 41181 41472 41516 41524 41565 41689 41916 42035 42212 42214 42486-42487 42586 42619 42670 42760 42944 42948 42972 42981 43127 43157 43187 43416 43420 43460 43531 44136 44307 44310 44316 44354 44371 44378 44389 44468 44651 45539 46436 46470 47539 47807 47824 47828 48072https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/652/A31?format=asciidefaultJ/A+A/652/A31/tablea1List of stars in the catalogrecnoRecord number assigned by the VizieR team.
