Photometric studies of δ Scuti stars. II. V1162 Orionis.

Abstract (from CDS):

New photometric (uvbyβ) observations of V1162 Orionis are reported. We derive a reddening value of Eb-y=0.021 mag and a metallicity of [Fe/H] = +0.1. Intrinsic b-y and c1 values indicate a mean effective temperature, <Teff≥7540 K, and a mean surface gravity, <logg≥3.96. Theoretical evolutionary tracks, along with pulsation models, indicate the mass of V1162 Ori is 1.8 M☉ and the age is 0.60 Gyr. New V magnitude CCD observations are also reported. A time of maximum light analysis shows that V1162 Ori has experienced a period break. In addition, the amplitude has dropped from ΔV=0.2 before the period break to ΔV=0.1 after the break.
