| | [106.05] Red Clump Stars - New, Improved Distance Indicator (Site not responding. Last check: 2007-10-08) |
 | | To date the red clump method was used to measure accurate distances to the Galactic center (Paczynski & Stanek 1998), M31 (Stanek & Garnavich 1998a), LMC (Udalski et al. |
 | | As with all the distance indicators, the main worry lies in the possible systematics of the method, in this case its dependence on the stellar metallicity and age. |
 | | Using the HST archival data and the fact that M31 and M33, including their clusters, span a broad range of ages and metallicities, we will be able to determine the age and metallicity dependence of the red clump brightness directly. |
