北冕座R星的一些观测问题

Some Observational Aspects of R Coronae Borealis Stars

N. Kameswara Rao

摘要:

讨论了与R-Cor-Bor星的演化状态和尘埃产生有关的一些观测问题。最近的工作,关于表面的丰度,恒星风和尘埃生产的证据,在这些高光度的氢缺乏恒星也进行了审查。还考虑了星风由表面磁场维持的可能性。

英文摘要:

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.
