Espectrofotometria de las estrellas simbióticas He2-417, He2-467 y He2-468.

A spectrophotometric study of He2-417, 467 and 468 is made. Their spectra show mainly emission lines of H I, He I and He II, as well as absorption bands characteristic of late-type stars. No forbidden lines were detected in the spectra of the objects. The authors report the line intensity ratios relative to Hβ and compare them with those previously reported in the literature. Some line ratios have varied in He2-417 and 467, the two objects with previous observations.
