The role of interstellar extinction law and bandwidth effects in multicolor photometry
The new mean interstellar extinction law covering the spectral range from 0.15 to 250 microns is derived. This extinction law yields R(BV) = A(V)/E(B-V) = 3.17 for OB stars. The very broad band structure of the extinction law in the visible region of the spectrum is confirmed. It is shown that the n...

| Zusammenfassung: | The new mean interstellar extinction law covering the spectral range from 0.15 to 250 microns is derived. This extinction law yields R(BV) = A(V)/E(B-V) = 3.17 for OB stars. The very broad band structure of the extinction law in the visible region of the spectrum is confirmed. It is shown that the new interstellar extinction law is suitable for the investigation of reddening parameters of photometric systems. The dependences of reddening parameters upon MK spectral types of stars in three photometric systems, Vilnius, UBV, and uvby, are discussed. (Author) |
