| Abstract: |
With our homogeneous photometric data of 8 dwarf spheroidal galaxies (dSphs, -9.5 < MV < -4.9) obtained by Subaru / Suprime-Cam, we have confirmed the anti-correlation between FBSS and MV found by Momany et al. (2007). We have also derived luminosity functions and radial distributions of blue straggler stars (BSSs) of three classical dSphs, Draco, Ursa Minor (UMi) and Sextans. The results suggest that BSSs in these dSphs were mainly formed from mass transfer in primordial binaries. |
