The studied sample comprises all [WR] CSs that are currently known. The analysis is based on recent observations of the parallax, proper motion, and color index of [WR] CSs from the Gaia space mission's early third release (eDR3) catalog, as well as common nebular characteristics. The results revealed an evolutionary sequence, in terms of decreasing Teff, from the early hot [WO 1] to the late cold [WC 12] stars. This evolutionary sequence extends beyond [WR] CS temperature and luminosity to additional CS and nebular characteristics. The statistical analysis shows that the mean final stellar mass and evolutionary age of the [WR] CS sample are 0.595+/-0.13M_{Earth}_ and 9449+/-2437 yr, respectively, with a mean nebular dynamical age of 7270+/-1380 yr. In addition, we recognize that the color of the majority (~85%) of [WR] CSs tends to be red rather than their genuine blue color. The analysis indicates that two-thirds of the apparent red color of most [WR]s is attributed to the interstellar extinction whereas the other one-third is due to the PN self-extinction effect.2023RAA....23i5021Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/23.I5021CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/84 : Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Acker+, 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RAA/23.I5021https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/23.I5021http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/23.I5021https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/23.I5021https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/23.I5021http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/23.I5021GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RAA/23.I5021/tablea1 (A summary of the basic parameters of the studied [WR] sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/23.I5021/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/23.I5021/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/23.I5021/tablea1?GETtext/xml+votable180.050000true273.3248-32.32860.0055555555555555566/361 1552 2979 3353 3365 3637 3819 4690 6292 12907 13055 13149 14214 14361 14443 15384 15430 15472 16886 20826 21666 22103 24036 28680 28711 28716-28718 28722 28728 28730 28733-28734 28746 28754 28771-28772 28777 28782 28805 28822-28823 28835 28840 28844 28859 28864 28881 28887 28889 28906 28984 29057 29062 29092 29094 29134 29160 29168 29171 29207 29213 29254 29266 29451 29466 29520 29886 30258 30282 30301 30303 30340 30635 30675 30699 37006 37345 37661 37757 37836 37914 37963 37982 38028 38034 38075 39801 41470 41574 41580 41646 41656 41664 41669 41674 41702 41789 41837 41864 41920 42044 42094 42140 42232 42313 42355 42474 42479 42490 42572 42709 42872 43169 47711 479213.313034785154005e-24 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RAA/23.I5021?format=asciiOpticaldefaultJ/other/RAA/23.I5021/tablea1A summary of the basic parameters of the studied [WR] sampleSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
