Feedback and Clusters in the Sdm Galaxy UGC 1281

= −16.04 it is somewhat less luminous than the SMC. UGC1281 alsobelongs to the class of low surface brightness (LSB) galaxies, where the buildupof the stellar disk occurred more slowly or started later than in normal galaxies(Rosenbaum & Bomans 2004). Surprisingly, Mould (2005) claimed the presenceof a red stellar thick disk in UGC1281, which appears at odds with the LSBnature of the galaxy.2.
