Description
The remarkable hot R Coronae Borealis (RCB) star DY Cen is revealed to
be the first and only binary system to be found among the RCB stars and
their likely relatives, including the extreme helium stars and the
hydrogen-deficient carbon stars. Radial velocity determinations from
1982 to 2010 have shown that DY Cen is a single-lined spectroscopic
binary in an eccentric orbit with a period of 39.67 days. It is also one
of the hottest and most H-rich member of the class of RCB stars. The
system may have evolved from a common envelope to its current form.

Low- to intermediate-mass (M < 8 solar masses, Ms) stars represent the majority of stars in the Cosmos. They finish their lives on the Asymptotic Giant Branch (AGB) - just before they form planetary nebulae (PNe) - where they experience complex nucleosynthetic and molecular processes. AGB stars are important contributors to the enrichment of the
