A high-metallicity host environment for the long-duration GRB 020819

Levesque, E M; Kewley, Lisa; Graham, J F; Fruchter, A S


We present spectroscopic observations of the host galaxy and explosion site of long-duration gamma-ray burst GRB 020819. We determine a metallicity for this host environment of log(O/H) + 12 = 9.0 0.1, by far the highest metallicity determined for a long-duration gamma-ray burst (LGRB) to date. We compare the metallicity and other properties of the GRB 020819 host environment to existing observations of LGRB host galaxies and consider the implications that this metallicity has for our...[Show more]
