We select a large volume-limited sample of low surface brightness galax- ies (LSBGs, 2021) to investigate in detail their statistical properties and their dif- ferences from high surface brightness galaxies (HSBGs,...

We study the ages of a large sample (1802) of nearly face-on disk low surface brightness galaxies (LSBGs) using the evolutionary population synthesis (EPS) model PEGASE with an exponentially decreasing star form...

The iron abundance gradient in the Galactic disk provides fundamental constraints on the chemical evolution of this important component of the Galaxy.However,there are still some arguments about the shape of the iron ...
