In this study optical/near-infrared ( NIR ) broad band photometry and optical spectroscopic observations of the GRB 030329 host galaxy are presented .
The Spectral Energy Distribution ( SED ) of the host is consistent with a starburst galaxy template with a dominant stellar population age of \sim 150 Myr and an extinction A _ { v } \sim 0.6 .
Analysis of the spectral emission lines shows that the host is likely a low metallicity galaxy .
Two independent diagnostics , based on the restframe UV continuum and the [ OII ] line flux , provide a consistent unextincted star formation rate of SFR \sim 0.6 M _ { \odot } yr ^ { -1 } .
The low absolute magnitude of the host ( M _ { B } \sim - 16.5 ) implies a high specific star formation rate value , SSFR = \sim 34 M _ { \odot } yr ^ { -1 } ( L / L ^ { \star } ) ^ { -1 } .
