cds-question@unistra.frgalaxiesspectroscopyh-ii-regionsWe analyse the stellar content of a large number of HII galaxies from the continua and absorption features of their spectra using population synthesis methods, in order to gain information about the star formation histories of these objects. We find that all galaxies of our sample contain an old stellar population (>=1Gyr) that dominates the stellar mass, and in a majority of these we also found evidence for an intermediate-age population >=50Myr apart from the presently bursting, ionizing young generation <=10^7^yr.2004A&A...423..133Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/423/133CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/423/133https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/423/133http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/423/133https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/423/133https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/423/133http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/423/133GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/423/133/position (*Galaxy positions (from Simbad or NED))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/423/133/position?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/423/133/position?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/423/133/position?GETtext/xml+votable180.050000true59.787083-39.1069440.0055555555555555566/4251 4276 4334 4370 4437 5186 5203 6293 17401 17725 17816 17821 17846 17865 17867 17888 17974 18004 18033 18038 18099 18136 18196 18629 18788 18793 20136 23566 24623 24733 24898-24899 25227 25253 25594 25659 25851 26028 26194 26234 26267 26278 26302 26346 26858 26963-26964 26971 26992 27351 27555 27653 27926 28154 31487 34036 34138 34170 34242 34250 34426 34478 34498 34576 34636 35194 35238 35420 35452 36648 38821 38829 38833 38850 38866 38875 38879 38906 39574 39610 39628 40276 40777 43429 43720 43754 43982 44026 44226 44236 44281 44548 44722 45468 46078 46329 46522 46540 46769 46790 46792 47072 47470 47523 47701 48506 48510https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/423/133?format=asciiOpticaldefaultJ/A+A/423/133/position*Galaxy positions (from Simbad or NED)recnoRecord number assigned by the VizieR team.
