Module 5, Assignment 8

Post your spectral class and temperature for three of the stars, identified by the HD number, as well as the spectral type, B, and V from SIMBAD. 

Include a screen shot of at least one spectrum (send to Chris Martin) with the lines you have identified.

Which technique do you think is more accurate for determining spectral class- temperature as determined by Wien’s Law or as determined by spectral lines?
