Finding RR Lyrae Stars with SkyMapper: An Observational Test

Akhter, Shaila; Da Costa, Gary; Keller, Stefan; Schmidt, Brian; Bessell, Michael; Tisserand, Patrick


One of the major science goals of the SkyMapper survey of the Southern Hemisphere sky is the determination of the shape and extent of the halo of the Galaxy. In this paper, we quantify the likely efficiency and completeness of the survey as regards the detection of RR Lyrae variable stars, which are excellent tracers of the halo stellar population. We have accomplished this via observations of the RR Lyrae-rich globular cluster NGC 3201. We find that for single-epoch uvgri observations followed...[Show more]
