Astronomy Tea Talk

There are only good reasons to study dwarf galaxies: because small is beautiful, because many are known but many are still looked for, because they are more complex and varied than the classical idiom "building blocks" would suggest, etc. I plan to discuss what can be learned from the Local Group dwarf spheroidal galaxies for galaxy formation, e.g, the connection between dark and luminous matter, the properties of the first stars, the driving parameters of the star formation histories, and finally shall make a short digression on how nucleosynthesis can benefit from these investigations.
