Hi all,
Here is a link to the short tutorial video I did on processing spectra with audela - spcaudace:

Congratulations Christian and Francois.
A VERY impressive set of spectra of WR stars with excellent agreement with the professional spectra.

Christian are you going to try and capture the set of all the WR stars visible from the North at this resolution on your list?

John

Another picture this time showing two spectra from 4th Oct in blue and 17th Oct in red of the pretty dramatic changes in the Halpha line of Alpha Cam.

Cheers

John

Thanks for the advice Valerie.

I'll try both suggestions to see which works best.

I have also been experimenting with removing the telluric lines using VSpec

Will post results up once I finally get all the processing done on the spectra

cheers

Preliminary results of my study of Alpha Cam over the last week. Diagram shows changes in the broad Halpha emission line over 5 nights. The line shape changes from being symmetric to being asymmetric. I now want to learn how to remove cosmics and tellurics as there are a few of these in the spectra ...

Thanks for you appreciation Christian.
And your link has some very nice spectra of Deneb in it.

I will hold onto my spectra in fits format and look forward to taking part in the campaign next year.

cheers

John

Here is an animated GIF of 5 spectra I took of Deneb over the past month showing changes at Halpha

Ok first comparison of Alpha Cam from two nights ago in blue and last night in pink.

Quite a few noticeable differences...

Paper I was reading was Markova 2002.
The resolution of the spectra taken was 15000 for one set of spectra and 22000 for the other. SNR varied from 50 to 275 for the spectra.

cheers

Hi all, I am going to try and monitor activity on Alpha Camelopardalis over next couple of weeks. The scientific papers state that this star is very active and I should be able to see profile changes every day Just wandered if anyone out there has ever studied/observed this star. My first spectra fr...
