Congratulations.
I especially appreciated the first paragraph of the article. I understood that viscous disks are ubiquitous structures at various scales in the universe, so observing Be stars was a means to study the physics of such disks. Now I see that symbiotic stars offer complementary information about accretion from disks.
If only the clouds would let me observe them....

Thank to all,
but the Letter is only the showcase, the most important are the spectra obtained by the team and gathered in the database

James:
Symbiotics (about 250 detected in the galaxy) are considered as excellent laboratories for many astrophysical phenomenon: accretion disks, wind from red giants, jets, hydrogen burning at the surface of white dwarfs, ...
About fifty are bright enough for amateur spectroscopy.
The orbital period (+++ 100 days) and time scale evolution (few days) allows a monotoring at a cadency of about 1/week or 1/month
For several objects, especially in high state, the time scale of variations become as low as day, hour or even minutes (for instance CH Cygni, V694 Mon)

At date, 4 publications are based at least partially spectra gathered by the team, and several others (CH Cyg, R Aqr, AG Dra ...) are under preparation
