cds-question@unistra.frstellar-associationspulsarsYoung isolated radio-quiet neutron stars are still hot enough to be detectable at X-ray and optical wavelengths due to their thermal emission and can hence probe cooling curves. An identification of their birth sites can constrain their age. For that reason, we try to identify the parent associations for four of the so-called Magnificent Seven neutron stars for which proper motion and distance estimates are available. We are tracing back in time each neutron star and possible birth association centre to find close encounters. The associated time of the encounter expresses the kinematic age of the neutron star which can be compared to its characteristic spin-down age. Owing to observational uncertainties in the input data, we use Monte Carlo simulations and evaluate the outcome of our calculations statistically. RX J1856.5-3754 most probably originated from the Upper Scorpius association about 0.3Myr ago. RX J0720.4-3125 was either born in the young local association TW Hydrae about 0.4Myr ago or in Trumpler 10 0.5Myr in the past. Also RX J1605.3+3249 and RBS 1223 seem to come from a nearby young association such as the Scorpius-Centraurus complex or the extended Corona-Australis association. For RBS 1223 also a birth in Scutum OB2 is possible. We also give constraints on the observables as well as on the radial velocity of the neutron star. Given the birth association, its age and the flight time of the neutron star, we estimate the mass of the progenitor star. Some of the potential supernovae were located very nearby (<100pc) and thus should have contributed to the 10Be and 60Fe material found in the Earth's crust. In addition, we reinvestigate the previously suggested neutron star/runaway pair PSR B1929+10/zeta Ophiuchi and conclude that it is very likely that both objects were ejected during the same supernova event.2010MNRAS.402.2369Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/402/2369CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AN/328/889 : Mean Radial Velocities of open clusters (Kharchenko+, 2007)J/AJ/117/354 : OB associations from Hipparcos (de Zeeuw+, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/402/2369https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/402/2369http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/402/2369https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/402/2369https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/402/2369http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/402/2369GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/402/2369/assoc (Positional and kinematical data for OB associations and clusters (table A1 in the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/402/2369/assoc?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/402/2369/assoc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/402/2369/assoc?GETtext/xml+votable180.050000true243.1629-24.10520.0055555555555555566/474 1287 1297 1548 1559 1769 2940 3011 3059 3063 3256-3257 3280 3307 3331 3384 3632 3712 3723 5425 13743 13960 14263-14264 14267 14301 14311 14353 14356 14628-14630 14644 14655 14690 14692 15385 15478 15651 15683 15703 17838 20797 21439 21456 21517 21644 22038 22056 22249 22252 22851 23637 23644 23717 23994 24333 27310 28803 28806 28809 28828 28890 28916 29089 29095 29116 29162 29456 29461 29463 29513 29532 30256 31338 31756 31790 33474 37012 37128 37231 37333-37334 37790 37865 37897 37900-37901 37926 38016 38018 38024 38026 38231 39216 39237 39249 39374 39386 39714 39739 39779 39804 39871 39907 39930 41472 41698-41699 41856 42153 42203 42213 42224 42303 42394 42458 42462 42489 42516 42661 42987 43028 43153 46143 47825https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/402/2369?format=asciiRadiodefaultJ/MNRAS/402/2369/assocPositional and kinematical data for OB associations and clusters (table A1 in the paper)recnoRecord number assigned by the VizieR team.
