Abstract:

Aims. The aim of this paper is to study the Gamma Ray Burst (GRB) environment through the analysis of the optical absorption features due to the gas surrounding the GRB. Methods. To this purpose we analyze high resolution spectroscopic observations (R=20000-45000, corresponding to 14 km/s at 4200Å and 6.6 km/s at 9000Å) of the optical afterglow of GRB050730, obtained with UVES@VLT ∼ 4 hours after the GRB trigger. Results. The spectrum shows that the ISMof the GRB host galaxy at z = 3.967 is complex, with at least five components contributing to the main absorption system. We detect strong CII*, Si II*, OI* and Fe II* fine structure absorption lines associated to the second and third component. Conclusions. For the first three components we derive information on the relative distance from the site of the GRB explosion. Component 1, which has the longest wavelength, highest positive velocity shift, does not present any fine structure nor low ionization lines; it only shows very high i...
