Abstract: |
Dwarf galaxies in the Local Group constitute a good representation
of dwarfs outside its border in the nearby Universe. In the near
infrared most of the brightest stars in these galaxies are on the
AGB and can be studied in some detail on an individual basis. This
allows for tests of models of the late stages of stellar evolution,
as well as providing information on the star formation history in
the parent galaxies. Some AGB stars are Mira variables, for which
an infrared period-luminosity relation exists, though distance
estimation is not entirely straightforward thanks to the reddening
produced by copious mass loss from some of these stars. This review
will focus on our current understanding of the photometric
characteristics of AGB stars in the Local Group and of prospects
for discovery as investigations push well beyond its boundary in
the near future. |
