%X We present the analysis of a sample of Hα, H β, and [O II]emission line galaxies from the OTELO survey, with masses typically below log(M*/Mꙩ) ∼ 9.4 and redshifts between z ∼ 0.4 and 1.43. We study the star formation rate, star formation rate density, and their number density and evolution with redshift. We obtain a robust estimate of the specific star formation rate—stellar mass relation based on the lowest-mass sample published so far. We also determine a flat trend of the star formation rate density (SFRD)and number density with redshift. Our results suggest a scenario of no evolution of the number density of galaxies, regardless of their masses, up to redshift z ∼1.4. This implies a gradual change of the relative importance of the star-forming processes, from high-mass galaxies to low- mass galaxies, with decreasing redshift. We also find little or no variation of the SFRD in the redshift range of 0.4 < z < 1.43.
