cds-question@unistra.frh-ii-regionsgalaxiesphotometrygalaxy-classification-systemsStudies of interacting galaxies have shown that dwarf galaxies may be produced in tidal tails during collisions. Numerical simulations suggest that the total detachment of the tidal dwarf requires the companion's mass to be comparable to or higher than that of the parent galaxy. This would imply that minor mergers (interaction between unequal mass galaxies) might not form tidal dwarf galaxies (TDGs). The objectives of the paper is to analyse the main properties of a sample of 116 HII regions previously selected from H{alpha} images of 11 minor mergers of galaxies and discuss the nature of these regions comparing their properties with those observed in HII regions in normal and isolated galaxies and TDG candidates. Individual parameters such as: blue absolute magnitude, MB, H{alpha} luminosity, L(H{alpha}), star formation rate, SFR(H{alpha}) and mass, M/M_{sun}_ of these regions were derived and compared with those of the HII regions in normal isolated galaxies, as well as in tidal dwarf candidates.2008A&A...481..645Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/481/645CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/428/837 : HII regions in minor mergers of galaxies (Ferreiro+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/481/645https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/481/645http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/481/645https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/481/645https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/481/645http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/481/645GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/481/645/tablea (HII region properties in a sample of minor merger)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/481/645/tablea?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/481/645/tablea?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/481/645/tablea?GETtext/xml+votable180.050000true194.727083-43.8380560.0055555555555555566/43503 43598 44256 45126 45339 45346 46214 46389 48140 48181 48293https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/481/645?format=asciiOpticaldefaultJ/A+A/481/645/tableaHII region properties in a sample of minor mergerrecnoRecord number assigned by the VizieR team.
