APPEARANCE OF NGC 7662 IN THE LIGHT OF He ı λ 10830

A direct photograph shows that the features present at λ 10830 are essentially those seen in He ı 4471, although they appear somewhat lesssharply defined at the optically thick wavelength. The interpretation of this effect as the result of scattering or as a population effect in the collisionally ex...

Zusammenfassung:A direct photograph shows that the features present at λ 10830 are essentially those seen in He ı 4471, although they appear somewhat lesssharply defined at the optically thick wavelength. The interpretation of this effect as the result of scattering or as a population effect in the collisionally excited λ 10830 line is discussed briefly.
