Does anyone have anything at all to say about this star other than that it exists and has a long list of catalogue numbers? I'm about to propose that it be deleted. It is variable and I'm a big fan of variable stars, but that in itself isn't sufficient. It wasn't in the self-consistent list of notable stars of Perseus (and every other constellation) compiled a few years ago, which is always a clue that we don't need an article for it.

OPPOSE I think it's important to have as many articles is possible, especially as the information on this page is arguably easier to understand and to read that the data on SIMBAD. — Preceding unsigned comment added by 88.109.188.99 ( talk) 15:48, 19 July 2016 (UTC)
I've just modified the article to reference two separate companion stars: an unseen hot spectroscopic companion and a rather distant visual companion. The article previously described these two as one object. However, the literature isn't clearcut on this. Many sources list a spectroscopic companion, described for example as "syncretic" so necessarily a close binary. Possibly spectral classes of "B7V and A have been offered. Other sources list the long-known and likely unrelated star BD+54°445 as a companion. This isn't an A or B7 star, and it couldn't possibly be described as syncretic, so presumably two separate objects although I can't find a single source that mentions them both as separate objects. To confuse matters Proust et al (1981) list XX Persei as M4Ib + B7V with the companion at 20.5". Is this just a typo and additionally confusion between the combined spectral class for the spectroscopic binary and the unrelated distant companion? I've assumed so, but it is less than obvious.
