The spectra of meteors from Halley’s comet

Conference paper

Summary

The spectra of 16 bright Orionid meteors are studied in the spectral range from 3440 to 8700Å. The brightest members of the group have peak absolute magnitudes near −8, indicating masses of a few grams and providing clear evidence that large particles from comet Halley survive to encounter the Earth’s atmosphere. Spectral lines from six neutral atomic species and three singly-ionized species are observed. The Orionid spectra are very similar to Perseid meteor spectra, suggesting any differences in abundances in the parent comets appear to be marginal for the elements observed.
