But there are also other reasons why these are intriguing times for RCB watchers. Such stars are few and far between, and for a long time only a small number were known. However, new search strategies are yielding rewards and the number of known or suspected RCBs and DY Pers are increasing as several groups of astronomers are datamining large photometric surveys.
One recent paper is a paper by Miller et al1 which uses machine learning tools on ASAS south photometry to look for the telltale signs of RCBs and DY Pers. (One wonders, by the way, when ASAS north will be released, and what new RCB candidates might be found there?)
One of their findings is ASAS 053302+1808.0, a carbon star which is a candidate for a new RCB/DY Per star.
I thought might have a look at what it is up to this observing season.
