P Cyg 2013-2016

Postby Olivier GARDE » Sat Apr 30, 2016 3:36 pm

Here's some comparaison graphe of P Cyg from July 2013 to April 2016 for H Alpha, H Beta, H Gamma and HeI 6678.
Depend of the balmer line, they are some difference between each curve and changes in intensity over time is not the same from one balmer line to another.
The order for H alpha (from minimum intensity to maximum) are Black curve, Green Curve, Blue Curve, Red curve and Cyan curve (the last spectrum from last night)

But for H Gamma, the orderer is Blue, Red, Black, Cyan and Green.

I'm looking to search some information about P Cyg, but I haven't find anything.

Hi Olivier,
your new spectrograph delivers excellent spectra.
Concerning the HeI 6678 see my summary of almost 10 years observation period.
http://astrospectroscopy.de/media/files/pcyg_He6678.pdf
It would be great, if you could take spectra further for that monitoring

Best wishes,
Ernst
