We present results from a well-studied δ Scuti star discovered in the Large Magellanic Cloud (LMC). The absolute magnitude of the variable was determined from the period-luminosity (P-L) relation for Galactic δ Scuti stars and from theoretical modeling of the observed B,V,I light curves with nonlinear pulsation models. The two methods give distance moduli for the LMC of 18.46 ± 0.19 and 18.48 ± 0.15, respectively, for a consistent value of the stellar reddening of E(B - V) = 0.08 ± 0.02. We…
