Spectroscopy

These spectra have been taken with the Staranalyser which is a 100l/mm blazed grating available here. I used the Artemis 285 for most of the spectra which gave me a dispersion of about 11 Angstroms per pixel. Lines have been identified where possible.

Reference Spectrum

Spectrum of Vega used to for calibration purposes. The prominent hydrogen Balmer lines in A-type stars provide a good reference to calibrate your spectra.

Wolf-Rayet Stars

		Wolf-Rayet stars are excellent targets for spectroscopy even at low resolution. Their prominent emission lines due to the outflow of material from the star stand out clearly.

		This spectrum of 3C273 was a 44 minute exposure. The Ha line was measured to determine the z value. This was measured as 0.157 in very good agreement with the published value of 0.158. The H-beta line does not give as good a result since it is overlapped at this resolution by OIII according to Christian Buil.
