Average [C/Fe] ratio is<br />
0.08±0.24, consistent with<br />
values predicted for a<br />
galaxy younger than 1 Gyr<br />
undergoing star formation<br />
[C/Fe] of component 3 is<br />
0.53±0.23, larger than in 2<br />
(-0.15±0.13), with [C]<br />
roughly constant.<br />
GRB 050730<br />
Since Fe dust grains are more efficiently destroyed than C dust grains by<br />
the GRB UV flux and blast wave (Perna, Lazzati & Fiore 2003), this<br />
suggests that component 2 is closer to the GRB than component 3.
