Further evidence for Raman scattering in RR Tel
1993 (English)In: Monthly notices of the Royal Astronomical Society, ISSN 0035-8711, E-ISSN 1365-2966, Vol. 264, no 4, 975-979979 p.Article in journal (Refereed) Published
Abstract [en]

Raman scattering of O VIlambdalambda13O2, 1308 photons on the ground level of neutral hydrogen has been suggested as the cause of the broad emission features at 6825 and 7088 Aring in the spectra of symbiotic stars. The authors report on the detection of other Raman lines in the optical spectrum of the symbiotic star RR Tel. The lines detected are two He II Balmer lines that are Raman-scattered to wavelengths close to hydrogen Hbeta and Hgamma. Another possible detection is scattered C III lambda977, which appears at about 4977 Aring in the optical spectrum
