cds-question@unistra.frradio-galaxiesh-i-line-emissionradial-velocityVoid population consists mainly of late-type and low surface brightness (LSB) dwarf galaxies, whose atomic hydrogen is the main component of their baryonic matter. Therefore observations of void galaxy HI are mandatory to understand both their evolution and dynamics. Our aim was to obtain integrated HI parameters for a fainter part of the nearby Lynx-Cancer void galaxy sample (total of 45 objects) with the Nancay Radio Telescope (NRT) and to conduct the comparative analysis of the whole 103 void galaxies with known HI data with a sample of similar galaxies residing in denser environments of the Local Volume. For HI observations we used the NRT with its sensitive antenna/receiver system FORT and standard processing. The comparison of the void and "control" samples on the parameter M(HI)/L_B_ is conducted with the non-parametric method "The 2x2 Contingency Table test". We obtained new HI data for about 40% of the Lynx-Cancer galaxy sample. Along with data from the literature, we use for further analysis data for 103 void objects. The proxy of the evolutional parameter M(HI)/L_B_ of the void sample is compared with that of 82 galaxies of morphological types 8-10 residing in the Local Volume groups and aggregates. At the confidence level of P=0.988, we conclude that for the same luminosity, these void galaxies are systematically gas-richer, in average by ~39%. This result is consistent with the authors' earlier conclusion on the smaller gas metallicities and evidences for the slower low-mass galaxy evolution in voids.2016A&A...596A..86Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/596/A86CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/415/1188 : Galaxies in the Lynx-Cancer void (Pustilnik+, 2011)J/other/AstBu/69.247 : Galaxies in Lynx-Cancer void (Perepelitsyna+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/596/A86https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/596/A86http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/596/A86https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/596/A86https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/596/A86http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/596/A86GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/596/A86/tablea1 (Parameters of the Lynx-Cancer void sample galaxies observed with NRT)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/596/A86/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/596/A86/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/596/A86/tablea1?GETtext/xml+votable180.050000true96.58737524.65555560.005555555555555556Cone search capability for table J/A+A/596/A86/tablea3 (Lynx-Cancer void galaxies with HI data from literature)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/596/A86/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/596/A86/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/596/A86/tablea3?GETtext/xml+votable180.050000true97.6202539.50377780.0055555555555555566/4121 4181 4213 4324 4334 4352 4575 4587 4602 4650 4719 4756 4887 4912 4933 4946 4948 4975 4983 5039 5059 5116 5258 5263 5267 5280 5283 5285 5287 5358-5359 5633 5635-5636 5641 5644 5660 5685-5686 5738 5758 5781 5834 5848-5849 6167 6204 6296 6320 6375 6399 6419 6443 6488 6500 6502 6548 6553 6560 6604-6605 6619 6623 6649 6752 6772-6773 6791 6868 6877 6921 6932 6937 6981 21996 22289 22298 22379 22420 22427 22495 23913 24011-24012 24034 24042 24437 27375 27383https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/596/A86?format=asciiRadiodefaultJ/A+A/596/A86/tablea1Parameters of the Lynx-Cancer void sample galaxies observed with NRTSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
