CCD uvbyβ photometry of young open clusters. I. The double cluster h and χ Persei.


Abstract (from CDS):

We present CCD uvbyβ photometry for stars in the nuclei of the young double cluster h and χ Persei. We find that the reddening is highly variable through the h Per nucleus, increasing from west to east, with values ranging from E(b-y)=0.328±0.022 in the western part to E(b-y)=0.465±0.024 in the south-east. Towards χ Per the reddening is fairly constant, with E(b-y)=0.398±0.025. Both clusters share a common distance modulus of 11.7±0.1mag, and an age of logt=7.10±0.05 years.
