cds-question@unistra.frgravitational-lensingastrometryI search for source-lens pairs in Gaia Data Release 2 (GDR2, Cat. I/345) that could potentially lead to microlensing events between 25th July 2014 and 25th July 2026. I estimate the lens masses using GDR2 photometry and parallaxes, and appropriate model stellar isochrones. Combined with the source and lens parallax measurements from GDR2, this allows the Einstein ring radius to be computed for each source-lens pair. By considering the source and lens paths on the sky, I calculate the microlensing signals that are to be expected.2018A&A...618A..44Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/618/A44CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/618/A44https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/618/A44http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/618/A44https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/618/A44https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/618/A44http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/618/A44GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/618/A44/tablea7 (Characteristics of the microlensing events ME34-ME76)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/618/A44/tablea7?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/618/A44/tablea7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/618/A44/tablea7?GETtext/xml+votable180.050000true15.669771708571.67701994560.0055555555555555566/3791 13892 14389 14397 15465 15670 17987 25141 28987 29006 29275 29848 29896 30210 30457 30518 33091 33096 34032 37207 37906 38061 38242 38456 38737 39709 40571 41125 41183 41444 42031 42074 42169 42290 42618 43088 43096 43239 43307 46566 46632 47823 48775https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/618/A44?format=asciidefaultJ/A+A/618/A44/tablea7Characteristics of the microlensing events ME34-ME76n_t0[(ab) ] Note on t0 (1)meta.notecharrecnoRecord number assigned by the VizieR team.
