A list of suspected symbiotic stars is published in AAVSO notice :https://www.aavso.org/aavso-alert-notice-650
A campaign on the request of Adrian Lucy and Jeniffer Solkolovski (Columbia University)
Faint targets, a nice goal for Alpy, LISA and other low resolution spectrograph.
What is expected is : late type continuum (giant M) and high ionisati on lines such as He II, [OIII], [Fe VII], Raman OVI ...
At least one of them is needed for identification of the target as a symbiotic star (See Belczinski & al., 2000)
The spectra will be added to ARAS database : http://www.astrosurf.com/aras/Aras_Data ... eStars.htm
Send spectra to lucy@astro.columbia.edu and francoismathieu.teyssier at bbox.fr
Good hunt!
