Dwarf Galaxies: Surface Photometry, Hi Observations

Scientific paper

CCD B and V observations of 16 low-surface-brightness galaxies and HI data for a subsample of 4 of them are presented. Both paired and isolated dwarf galaxies are observed to study possible environmental effects on their characteristics. Most of the observed galaxies are true dwarfs with -8.0>=M_B_>=-16.0, blue colours (0.16<=B-V<=0.76) and low central surface brightnesses 22.2<=μ_B_<=24.0mag/arcsec^2^. Most of them show exponential light profiles with a central light depression. About half of them have bright generally blue knots or peculiar loops.
