"Probing
the Outer Halo Galactic Formation: The new SDSS dSph Galaxies and
their Variable Stars" |
|
With the discovery of new dwarf spheroidal galaxies from the Sloan Digital Sky Survey, we have a larger pool of possible candidate objects that may have influenced the formation of our Galaxy. We studied five of these new galaxies for their variable star content, specifically for the RR Lyrae variables. RR Lyrae variable stars, which belong to an old stellar population, are effectively eyewitnesses to the formation of the Galaxy, as well as useful distance indicators. I will discuss our results from our studies for five of these dwarf galaxies. |
