Time one night or a life time !


Symbiotic stars are interacting binary red giant & hot stars. The red giant loose material which is accreted by the hot star (main sequence star, white dwarf or neutron star). Outbursts occurs over the years which make them brighter and easier to record in spectroscopy.


I would recommend the excellent web page from François Teyssier :

While in french, the line identification, catalog, spectroscopic atlas and almost complete bibliography are easy to access in any language!
