Abstract

The nearby Lynx-Cancer void is a good laboratory to study the effect of very rarefied environment on the evolution of the least massive dwarf galaxies. A recently compiled sample of this void’s galaxies includes about one hundred objects with MB in the range −12 to −18 mag. Good quality images are available in the SDSS database for ∼80% of the sample. Their u, g, r, i, z photometry allows one to derive galaxy stellar mass (and, incorporating HI data, gas mass-fraction) and ages of visible stellar populations, and hence, the epoch of their formation (first SF episode). We present the first photometric results of the ongoing study of the Lynx-Cancer void.
