cds-question@unistra.frearly-type-starsinfrared-sourcespolarimetryThe Galactic Center offers unique opportunities to study stellar and bow-shock polarization effects in a dusty environment. The goals of this work are to provide near-infrared (NIR) polarimetry of the stellar sources in the central parsec at the resolution of an 8m telescope for the first time, along with new insights into the nature of the known bright bow-shock sources. We use adaptive-optics assisted observations obtained at the ESO VLT in the H- and Ks-band, applying both high-precision photometric methods specifically developed for crowded fields and a newly established polarimetric calibration for NACO to produce polarization maps of the central 3"x10", in addition to spatially resolved polarimetry and a flux variability analysis on the extended sources in this region.2011A&A...534A.117Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/534/A117CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/502/91 : Proper motions of stars near SgrA* (Schoedel+, 2009)J/A+A/511/A18 : NIR observations of stars near SgrA* (Schoedel+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/534/A117https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/534/A117http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/534/A117https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/534/A117https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/534/A117http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/534/A117GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/534/A117/pollist (H- and Ks-band polarization parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/534/A117/pollist?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/534/A117/pollist?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/534/A117/pollist?GETtext/xml+votable180.050000true266.4177297-29.00755220.0055555555555555566/288307.952274030004205e-20 1.2934455535160846e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/534/A117?format=asciiInfrareddefaultJ/A+A/534/A117/pollistH- and Ks-band polarization parameterspaH?
