cds-question@unistra.frinfrared-sourcesastrophysical-masersradio-astronomyinfrared-photometryThe observations in the 28SiO J=1-0 v=1, J=1-0 v=2 lines and the 29SiO J=1-0, v=0 lines were simultaneously made toward 181 color-selected IRAS sources in the outer disk of the Galaxy (at longitudes between 90 deg and 250 deg). The 28SiO lines were detected in 63 sources (56 new) and the 29SiO line in 11 sources (9 new). Most of the detections are optically variable stars, mainly Mira-type variables and a few semiregular variables. The detection rate (35%) is much lower than that of the bulge survey performed by the same observational system - the 45m telescope at Nobeyama Radio Observatory. The lower detection rate of SiO maser emission is partly attributed to the increase of contaminations by stars with C-rich circumstellar envelopes and young stellar objects in the outer disk sample. The kinematical implications of the observational results are also discussed. The luminosity distances to the SiO maser sources are estimated from their IRAS fluxes at 12um and colors. By combining the SiO radial velocity and the luminosity distance, the rotation curve of the outer Galactic disk is found to be slightly falling within the Galactocentric distance between 8.5 and 12kpc. The sources located within 20deg from the Galactic anticenter direction are used to check for a peculiar motion of the local standard of rest.1996ApJS..106..463Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/106/463CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/106/463https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/106/463http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/106/463https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/106/463https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/106/463http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/106/463GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/106/463/table3 (Infrared properties and observation parameters of the nondetections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/106/463/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/106/463/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/106/463/table3?GETtext/xml+votable180.050000true2.449665.32090.0055555555555555561.2932132981302573e-20 2.1346512726771855e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/106/463?format=asciiInfraredRadiodefaultJ/ApJS/106/463/table1aLine parameters of Gaussian components of the v=1 and v=2 detectionsrecnoRecord number assigned by the VizieR team.
