LISA Symbiotic & Other stellar spectra, 9-16Jun18 Mt. Pinos,

Postby James Foster » Mon Jul 02, 2018 11:26 am

Here is a small web page of the 34 LISA spectra of Symbiotic stars & other objects shot 9-16Jun18 from Mt. Pinos, CA (2500 meters elevation):
http://astroimage.info/spectra/pinosjune18spectra.htm
Taken with a 33cm aperture classical cassegrain telescope working at F/7.5 for average spectral resolution of R=850.
These have all been submitted to the BAA Spectroscopy Database. Some like ES Dra and AT2017eaw were shot in poor conditions and/or insufficient exposure.
I plan to shoot most of these again in July, August & October from the same location. Let me know if there are any other objects; as low as -35 dec and close
to the meridian line within this time frame. I can shoot spectra for objects brighter than 15.7 Vmag. Thanks for looking.

James

Super boulot, il faudrait le voir sur un grand poster pour bien voir toutes ces étoiles et leurs particularités.

Very nice work.
As I looked at the spectra of the late type stars I wondered if any could be found in Bulletin 81, the predicted maxima and minima for long period variables of the AAVSO
https://www.aavso.org/sites/default/files/Bulletin2018.pdf
Unfortunately I couldn’t find any.
Is there a similar database with the predicted maxima and minima for late type symbiotic stars?
