Stellar Variability and Distance Indicators in the Near-infrared in Nearby Galaxies. II. Pulsating Stars in the Carina Dwarf Spheroidal

We present homogeneous, near-infrared ( JHK _s bands) time-series observations of the classical Carina dwarf spheroidal (dSph) galaxy to determine accurate and precise distances using the pulsating stars as standard candles. These observations cover two Carina dSph fields ( $\sim 10\mathop{.}\limits...
