Chemical abundances of metal-poor RR Lyrae stars in the Magellanic Clouds

Chemical abundances of metal-poor RR Lyrae stars in the Magellanic Clouds

We present for the first time a detailed spectroscopic study of chemical element abundances of metal-poor RR Lyrae stars in the Large and Small Magellanic Cloud (LMC and SMC). Using the MagE echelle spectrograph at the 6.5 m Magellan telescopes, we obtain medium resolution (R ~ 2000-6000) spectra of...
