The extinction toward the Galactic Bulge from RR Lyrae stars.

KUNDER A., POPOWSKI P., COOK K.H. and CHABOYER B.

Abstract (from CDS):

We present mean reddenings toward 3525 RR0 Lyrae stars from the Galactic bulge fields of the MACHO Survey. These reddenings are determined using the color at minimum V-band light of the RR0 Lyrae stars themselves and are found to be in general agreement with extinction estimates at the same location obtained from other methods. Using 3256 stars located in the Galactic Bulge, we derive the selective extinction coefficient RV,VR= AV/E(V-R) = 4.3±0.2. This value is what is expected for a standard extinction law with RV,BV= 3.1±0.3.
