Study of galaxies in a nearby Lynx-Cancer Void: project and first results Pustilnik S.A. and Tepliakova A.L. (SAO) Dwarf galaxies residing in the very low density environment (voids) are expected in the frame of modern cosmological CDM models to form later and to evolve more slowely in respect of their counterparts in a more typical environment. The available data on evolution of void population are rather scarce and indirect. Therefore, to check this prediction directly is important by itself. Also, to find such unevolved galaxies is interesting since they best approximate the properties of "primordial" galaxies in the high-redshift Universe. We study late-type dwarfs in and around a nearby Lynx-Cancer void with the aim to obtain their evolutionary parameters: the ISM metallicity and gas-mass fraction. Its proximity allows at first time to study properties of galaxies in voids down to M_B=-13. These parameters will be used to check an effect of global environment on galaxy evolution. We present the results of our 6m telescope spectroscopy of 8 dwarfs in this region, the summary of the project status and preliminary analysis of the data.
