Red variables in the OGLE-II data base - III. Constraints on the three-dimensional structures of the Large and Small Magellanic Clouds

Lah, Philip; Kiss, L L; Bedding, Timothy Russell

Description

We present an analysis of the 3D structure of the Magellanic Clouds, using period-luminosity (P-L) relations of pulsating red giants in the OGLE-II sample. By interpreting deviations from the mean P-L relations as distance modulus variations, we examine the 3D distributions of the sample. The results for the Large Magellanic Cloud, based solely on stars below the tip of the Red Giant Branch (LMC), confirm previous results on the inclined and possibly warped bar of the LMC. The depth variation...[Show more]
