cds-question@unistra.frmilky-way-galaxyspectroscopic-binary-starssupernovaeradial-velocityvisible-astronomyBinary stars are gravitationally bound stellar systems where the evolution of each component can significantly influence the evolution of its companion and the system as a whole. In certain cases, the evolution of these systems can lead to the formation of a red giant-white dwarf system, which may exhibit symbiotic characteristics. The primary goal of this work is to contribute in a statistical way to the estimation of the symbiotic system (SySt) population in the Milky Way and in the dwarf galaxies of the Local Group (LG). Additionally, we aim to infer the maximum contribution of SySt to Type Ia supernova (SN Ia) events. Given the significant discrepancies in previous estimates, we propose two distinct approaches to constrain the expected SySt population: one empirical and another theoretical. These approaches are designed to provide a robust estimation of the SySt population. For the Milky Way, we utilized position and velocity data of known SySts to determine their distribution. Based on these properties, we constrained the lower limit for the Galactic SySt population in the range of 800-4100. Our theoretical approach, which relies on the properties of zero-age main-sequence binaries and known binary evolutionary paths, suggests a SySt population of (53+/-6)x10^3^SySt in the Galaxy. The statistical SySt populations for LG dwarf galaxies are one to four orders of magnitude lower, primarily dependent on the galaxies' bolometric luminosity and, to a lesser extent, their binary fraction and metallicity. In this work, the contribution of the single-degenerate channel of SNe Ia from symbiotic progenitors is estimated to be of the order of 1% for the Galaxy.2025A&A...698A.155Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/698/A155CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/352 : Distances to 1.47 billion stars in Gaia EDR3J/ApJS/240/21 : Symbiotic stars with 2MASS, WISE + Gaia data (Akras+, 2019)http://astronomy.science.upjs.sk/symbiotics/ :https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/698/A155https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/698/A155http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/698/A155https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/698/A155https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/698/A155http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/698/A155GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/698/A155/table1 (SySt assembled data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/698/A155/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/698/A155/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/698/A155/table1?GETtext/xml+votable180.050000true11.15540.679290.0055555555555555566/2558 2623 2906 3462 6170 7069 8669 10800 11673 11958 12440 12551 12912 13286 13797 14484 14549 15135 17192 19145 21422 21620 21746 22420 22457 22946 24689 26247 28682 28696-28697 28703 28709 28730 28772 28779 28783 28792 28817 28822 28837 28841-28842 28845 28856 28886 28889 28953 28990 29004 29032-29033 29049 29067 29073 29096 29204 29229 29248 29277 29285 29314 29536 29539 29574 29664 29854 29902 29928 30280 30320 30325-30326 30374 30440 30680 31172 31862 32149 32173 32191 32484 32585 37212 37232 37366 38090 39763 39773 39847 40120 41339 41370 41454 41598 41716 42044 42165 42196 42270 42357 42365 42477 42492 42511 42521 42609 42633 42742 42756 42831 42862 42911 42944 43062 43074 43086 43810 43992 44357 44598 45101 45666 45737 46079 47780 47785 48738 49087https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/698/A155?format=asciiOpticaldefaultJ/A+A/698/A155/table1SySt assembled datarecnoRecord number assigned by the VizieR team.
