Wavelet analysis of variable Wolf-Rayet emission lines
Sébastien Lépine · Symposium - International Astronomical Union · 1995
A new powerful mathematical tool for the analysis of structures on spectral lines is presented: wavelet analysis. Applied to variable Wolf-Rayet emission lines, it allows one to extract efficiently and in an objective way, individual sub-structures and compare some of their physical properties: integrated flux f, velocity dispersion σv, projected velocity v and acceleration a.
