Contribution
It introduces a comprehensive chemical evolution model that includes dust production to constrain the star formation history of a high-redshift GRB host galaxy.
Findings
Derived elemental abundances for multiple elements.
Estimated dust-related quantities and specific star formation rate.
Compared properties of the GRB host with Quasar Damped Lyman Alpha absorbers.
Abstract
The long GRB 050730 observed at redshift z ~ 4 allowed the determination of the elemental abundances for a set of different chemical elements. We use detailed chemical evolution models taking into account also dust production to constrain the star formation history of the host galaxy of this long GRB. For the host galaxy of GRB 050730, we derive also some dust-related quantities and the the specific star formation rate, namely the star formation rate per unit stellar mass. We copare the properties of the GRB host galaxy with the ones of Quasar Damped Lyman Alpha absorbers.
