To study this motion on a much larger scale in the Galaxy, we newly surveyed 134 evolved stars off the Galactic plane by SiO maser lines, obtaining accurate radial velocities of 84 detected stars. Together with the past data of SiO maser sources, we analyzed the radial-velocity data of a large sample of sources distributed in a distance range of about 0.3-6kpc in the first Galactic quadrant. At Galactic longitudes between 20{deg} and 40{deg}, we found a group of stars with large negative radial velocities, which deviate by more than 100km/s from the Galactic rotation. We show that these deviant motions of maser stars are created by periodic gravitational perturbation of the Bulge bar, and that the effect appears most strongly at radii between corotation and outer Lindblad resonances. The resonance effect can explain the displacement of positions from the Galactic plane as well.2010PASJ...62..525Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASJ/62/525CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/ApJS/106/463 : SiO maser sources (Jiang+ 1996)J/A+AS/127/185 : SiO masers in OH/IR stars, proto-PN and PN (Nyman+ 1998)J/A+AS/132/211 : Interstellar SiO sources (Harju+ 1998)J/A+A/391/967 : H2O and SiO masers in the Galactic center (Sjouwerman+, 2002)J/A+A/393/115 : 86GHz SiO maser survey of late-type stars (Messineo+, 2002)J/A+A/418/103 : 86GHz SiO maser survey in the Inner Galaxy (Messineo+, 2004)J/A+A/435/575 : 86GHz SiO maser survey of late-type stars (Messineo+, 2005)J/ApJ/669/446 : Observations of SiO masers (Nakashima+, 2007)J/PASJ/53/293 : IRAS/SiO sources toward Galactic Bulge (Deguchi+, 2001)J/PASJ/54/719 : IRAS/SiO sources in the Galactic bulge (Deguchi+, 2002)J/PASJ/55/203 : SiO maser survey toward inner Galactic disk (Nakashima+, 2003)J/PASJ/55/229 : SiO maser survey of cold IRAS sources (Nakashima+, 2003)J/PASJ/56/261 : SiO maser survey in Galactic center (Deguchi+, 2004)J/PASJ/56/765 : SiO maser survey of IRAS sources (Degychi+, 2004)J/PASJ/58/529 : SiO Maser Survey in Galactic Bulge (Fujii+, 2006)J/PASJ/59/559 : SiO maser search off the Galactic plane (Deguchi+, 2007)J/PASJ/62/391 : SiO and H2O maser in Galactic disk clusters (Deguchi+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASJ/62/525https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASJ/62/525http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASJ/62/525https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASJ/62/525https://vizier.iucaa.in/viz-bin/votable?-source=J/PASJ/62/525http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASJ/62/525GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASJ/62/525/catalog (Results of the observations: SiO masers and non-detections, and IR properties of the stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/62/525/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/62/525/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/62/525/catalog?GETtext/xml+votable180.050000true189.2787917-17.52552780.005555555555555556Cone search capability for table J/PASJ/62/525/table4 (Candidates for deviant motion (|b|>3{deg}))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/62/525/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/62/525/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/62/525/table4?GETtext/xml+votable180.050000true246.4477518.89244440.0055555555555555566/8532 8550 9259 10011 12300 12802 12817 12834 12839 12854 12936 12941 12944 12948 12954 12971 14411 14490 15092 16088 16318 25032 28113 29053 29055 29141 29148 29150 29159 29173-29175 29180 29360 29549 29560 29636-29637 29645 29649 29653 29655 29663 29672 29696 29708 29734 29742 29832-29833 29851 29855 29857 29862 29864-29866 29869 29871 29873 29880 29883 29887 29896 29935 29950 30106 30127 30134 30137 30188 30228 30273 30276-30278 30295 30336 30338-30339 30349 30360 30362-30363 30366 30368 30381 30393 30398 30435 30439 30443 30457 30460 30462 30486 30497 30570-30571 30573 30581 30591 30678 30769 31030 31034 31464 31552 31600 31764 31811 31815 31825 31827-31828 31832-31834 31840 31886 31922 31944 32005 32019 32022 32029 32055 32073 32076 32109 32126 32314 32322 32500 32527 32696 44373 488601.2932132981302573e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASJ/62/525?format=asciiOpticalRadiodefaultJ/PASJ/62/525/catalogResults of the observations: SiO masers and non-detections, and IR properties of the starsObsDateObservation datetime.epoch;obsnullablerecnoRecord number assigned by the VizieR team.
