Contribution
It synthesizes recent observational data on R CrB stars, highlighting their dust production, surface composition, and the role of magnetic fields in stellar winds.
Findings
Evidence of dust production in R CrB stars
Surface abundances indicating evolutionary status
Stellar winds possibly maintained by magnetic fields
Abstract
Some of the observational aspects related to the evolutionary status and dust production in R Cor Bor stars are discussed. Recent work regarding the surface abundances, stellar winds and evidence for dust production in these high luminosty hydrogen deficient stars are also reviewed. Possibility of the stellar winds being maintained by surface magnetic fields is also considered.
