cds-question@unistra.frgalaxiesphotometryultraviolet-astronomyinfrared-photometryWe present images of NGC 7331 obtained with GALEX and Spitzer, tracing UV and IR signatures of star formation. NGC 7331's morphology at 8-850um is dominated by a central dust ring. This structure is a vigorous site of star formation (hosting one-third of the present activity) but remains inconspicuous in our GALEX UV imagery. Radial profile analysis and photometry for discrete UV- and UV+IR-selected substructures indicate a decline in UV extinction with increasing galactocentric distance, although highly attenuated star-forming regions can be found throughout the disk. UV-optical surface brightness profiles suggest a recent birthrate parameter (b_8_) that is highest in the outer part of the disk, even though the local star formation intensity peaks in the ring. Bolometric luminosity and UV attenuation are correlated in substructures on 0.4kpc scales, with a relationship similar to that established for starburst galaxies.2007ApJS..173..572Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/173/572CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/586/794 : Multiwavelength luminosities of galaxies (Bell, 2003)J/A+AS/131/317 : NGC 7331 HII regions catalogue (Petit 1998)J/A+A/285/404 : Star formation in compact groups of galaxies (Moles+ 1994)J/A+A/288/713 : Star formation in galaxies (Firmani+ 1994)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/173/572https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/173/572http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/173/572https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/173/572https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/173/572http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/173/572GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/173/572/table2 (Photometry of UV+IR and UV-selected substructures in NGC 7331)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/173/572/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/173/572/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/173/572/table2?GETtext/xml+votable180.050000true339.27291734.4094440.0055555555555555566/13522https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/173/572?format=asciiUVOpticalInfrareddefaultJ/ApJS/173/572/table2Photometry of UV+IR and UV-selected substructures in NGC 7331recnoRecord number assigned by the VizieR team.
