AAVSO Centennial Review on YSOs
If you have not yet seen it on the front page of the AAVSO website, we have just published Dr. William Herbst's review article on "The Variability of Young Stellar Objects." This article is one of several invited reviews on current topics in variable star astronomy to be published in JAAVSO volume 40, celebrating our organization's centennial year.
You can find the review here. Many thanks to Bill Herbst for his great review!
