Title:Star Formation in Balmer Break galaxies at z < 1.5

Abstract:
We present a spectroscopic study about of 100 Balmer break galaxies, which show 
signs of star formation trough the presence of at least one of the [OII]3727 
AA, Hbeta 4861 AA or Halpha 6563 AA. These galaxies span a redshift range from 
0.045 to 1.475. We investigate the relation between star formation and stellar 
mass and its dependance with redshift. We found that more massive galaxies have 
higher SFR values but lower SSFR than less massive galaxies. At a given mass, 
high redshift galaxies have on average larger SFR and SSFR values than low 
redshift galaxies. Finally, bluer galaxies have larger SSFR values than redder 
galaxies, and for a given color the SSFR would be on average larger for higher 
redshift galaxies.
