Disappearing - Reappearing Star: KH 15D
In case anyone finds this interesting:
KH 15D – Is a 16th magnitude star that periodically dims out by 3 magnitudes in a regular cycle, much more than other eclipsing binary formations. Why? It might be a solar system in the making, with a younger version of our Sun, and a proto-planetary disk of dust, rocks and larger asteroids, seen edge on from Earth. Van Vleck Observatory web site explains: http://www.astro.wesleyan.edu/research/kh15d/ Also found in a related link: Defining a Planet: http://exoplanets.org/defn.html
