Long duration gamma-ray bursts (LGRBs) preferentially occur in high surface brightness regions of low-luminosity host galaxies (Fruchter et al 2006). LGRB progenitors must therefore also live in such environments. In order to constrain the nature of LGRB progenitors, we are studying the environments of stars in the Magellanic Clouds, as a function of stellar type and population age, to determine which types of stars are distributed like LGRBs.
We are following the statistical methods for analyzing LGRB environments laid out by Fruchter et al. (2006). Since LGRB hosts are often blue, irregular, and of low metallicity, the Magellanic Clouds make a suitable laboratory for studying GRB environments. Furthermore, the Magellanic Clouds are at an ideal distance, such that we can study the distribution of diffuse light on the galaxy and correlate that to the positions of individually resolved stars in the same way that Fruchter et al. correlated the distribution of light to the position of the gamma-ray burst. We are using photmetry from the Magellanic Clouds Photometric Survey (Zaritsky, Harris, and Thompson 1997) and combining it with Pickles templates (1998) to obtain estimates of stellar type for each star in the catalogue. We then correlate the locations of the stellar types to the distribution of diffuse light on the Magellanic Clouds and compare this correlation to the environments of LGRBs within their hosts.
