Our sample comprises 428 galaxies of various morphologies in the redshift range 0.002<z<0.02 (8-87Mpc) with panchromatic data from the Galaxy and Mass Assembly survey. We find that BSph galaxies are structurally (mean effective surface brightness, effective radius) very similar to their passively evolving red counterparts. However, their star formation and other properties such as colour, age, and metallicity are more like star-forming spirals than spheroids (ellipticals and lenticulars). We show that BSph galaxies are statistically distinguishable from other spheroids as well as spirals in the multidimensional space mapped by luminosity-weighted age, metallicity, dust mass, and specific star formation rate. We use HI data to reveal that some of the BSphs are (further) developing their discs, hence their blue colours. They may eventually become spiral galaxies - if sufficient gas accretion occurs - or more likely fade into low-mass red galaxies.2018MNRAS.475..788Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/475/788CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/452/2087 : Galaxy And Mass Assembly (GAMA): DR2 (Liske+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/475/788https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/475/788http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/475/788https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/475/788https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/475/788http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/475/788GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/475/788/table1 (Complete 428 galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/475/788/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/475/788/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/475/788/table1?GETtext/xml+votable180.050000true212.619010.946060.0055555555555555565/1024 5462 5468 6483 6486 6488-6489 6569-6571 6825 6/4101 4103-4105 4107-4108 8202-8203 8224 21839 21843-21845 21852-21854 21876-21877 25583 25587 25591 25593-25595 25597 25599 25911 25918 25927 25931 25948-25949 25951 25960-25961 25966-25968 25970-25974 25977-25979 26001 26005 26007 26049-26051 26053-26054 26057 26060 26243 26248 26250 26252 26255 26273 26275 26288 26290-26291 26297 26950-26951 26953 26956 26960 26962-26964 26966-26970 26972-26973 26992-26993 27276 27278-27279 27298-27299 27305-27307 27310-27312 27314-27315 27318 27321-27324 27649-27652 27654 27656https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/475/788?format=asciiOpticalRadiodefaultJ/MNRAS/475/788/table1Complete 428 galaxiesrecnoRecord number assigned by the VizieR team.
