J/BaltA/11/441   Extinction along Cam and Per border  (Zdanavicius+, 2002)

Interstellar extinction along the Camelopardalis and Perseus border. Zdanavicius J., Zdanavicius K. <Baltic Astron., 11, 441 (2002)> =2002BaltA..11..441Z
ADC_Keywords: Molecular clouds ; Interstellar medium ; Photometry, Vilnius Keywords: interstellar medium: extinction - techniques: photometric: Vilnius photometric system - stars: fundamental parameters Abstract: Interstellar extinction in a ∼100 sq. degree area at the Camelopardalis and Perseus border is investigated. The study is based on the results of photoelectric photometry of 455 stars in the seven-color Vilnius photometric system published earlier. The nearest 100 stars with Hipparcos parallaxes show that the extinction starts to grow at a distance of 110-150pc. At a distance of 1 kpc the extinction Av is within 1.2 and 2.4mag. At larger distances the extinction determination is affected by the limiting magnitude effect. At distances >1.5kpc a number of O-B stars with the extinctions between 2 and 4mag are found.
