Distance to the RR Lyrae Star V716 Monocerotis
/ Authors
/ Abstract
We present high‐quality BVRI CCD photometry of the variable star V716 Monocerotis (=NSV 03775). We confirm it to be an RR Lyrae star of variability type ab (i.e., a fundamental‐mode pulsator) and determine its metallicity ([Fe/H] = -1.33 ± 0.25), luminosity (MV = 0.80 ± 0.06), and foreground reddening [E(B−V) = 0.05–0.17] from the Fourier components of its light curve. These parameters indicate a distance of 4.1 ± 0.3 kpc, placing V716 Mon near the plane of the Galaxy well outside the solar circle.
