Mizar double star spectroscopic

Post by Olivier GARDE »

during one month, I always begin observations session by taking a spectrum of Mizar (to check the focus of my spectrograph).
So I have save each spectrum and now I can animate them.

Here's the result with heliocentric correction, but I didn't remove teluric lines.

And the 2D dynamic spectrum of this sequence

Belle manip
Résultat propre et spectaculaire, ça donne des idées !
Il n'y a plus qu'a calculer l'orbite ;)

Bravo, une très belle idée et une très belle réalisation!

A noter une binaire qui devient un peu plus visible à cette époque en fin de nuit: Algol. Parfois il y a un pic en émission, lié à un "hot spot" car les étoiles sont assez proches et en interaction...

Cordialement,

Nice, I am doing Mizar spectra too, at R=4000. I am able to see how h-alpha line becomes double. I plan to share my results soon.

¿How did you get that 2d espectral sequence?
Regards
Miguel

Hi Miguel,

For the 2D spectrum, have a look of this tutorial of Christian Buil :
http://www.astrosurf.com/buil/isis/isis_tuto/tuto4.htm

Only in French I think.... But maybe try with google translate.
