Average Star Formation Parameters in the Local Volume of the Universe

Based on the fluxes of 1400 nearby galaxies observed in far ultraviolet ($\mathrm{F}\mathrm{U}\mathrm{V}$) and in the H$\alpha$ line, we determined the global star formation rate per unit Universe volume, $j_{\mathrm{S}\mathrm{F}\mathrm{R}}=(1.34\pm 0.16){10}^{-2}{M}_{\odot }$ yr${}^{-1}$ Mpc${}^{-3}$. With the current star formation rate (SFR), ($65\pm 4)$% of the observed stellar mass is reproduced in the cosmological time of 13.8 billion years. The neutral gas reserves in the Local Volume with a radius of 11 Mpc will facilitate the current SFR on a scale of approximately another 5 billion years.
