cds-question@unistra.frpulsarsx-ray-sourcesinfrared-sourcesastronomical-object-identificationWe present near-infrared and optical observations of the field of the anomalous X-ray pulsar 1E 2259+586 taken with the Keck telescope. We derive a sub-arcsecond Chandra position and tie it to our optical reference frame using other stars in the field. We find a very faint source, K_S_=21.7+/-0.2mag, with a position coincident with the Chandra position. We argue that this is the counterpart. In the J, I, and R bands, we derive (2{sigma}) limits of 23.8, 25.6, and 26.4mag, respectively. As with 4U 0142+61, for which a counterpart has previously been found, our results are inconsistent with models in which the source is powered by accretion from a disk but may be consistent with the magnetar model.2001ApJ...563L..49Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/563/L49CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/563/L49https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/563/L49http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/563/L49https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/563/L49https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/563/L49http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/563/L49GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/563/L49/table1 (Positions and magnitudes of selected objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/563/L49/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/563/L49/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/563/L49/table1?GETtext/xml+votable180.050000true345.2834458358.877194440.005555555555555556Cone search capability for table J/ApJ/563/L49/table2 (Chandra X-ray point sources on S3 and their (tentative) counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/563/L49/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/563/L49/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/563/L49/table2?GETtext/xml+votable180.050000true345.1391208358.879755560.0055555555555555566/14305https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/563/L49?format=asciiX-rayInfraredRadiodefaultJ/ApJ/563/L49/table1Positions and magnitudes of selected objectsrecnoRecord number assigned by the VizieR team.
