== Eclipsing young stellar objects == Characteristics: * long-lasting eclipses by disk material * shapes can be irregular * timescales days to years * high amplitudes possible (several mags), cutoff of 1mag is probably useful * very few known, every new detection would help Trigger is necessary to figure out the origin of the eclipse -- the eclipsing body could be a part of the disk, clumps, protoplanetary structures, etc. Examples: * KH15D: recurrent, but changing eclipses- see Herbst et al. 2012 http://adsabs.harvard.edu/abs/2010AJ....140.2025H * RW Aur: singular event - http://figshare.com/articles/A_huge_eclipse_in_the_young_star_RW_Aur/92169 * YLW 16 A: has smaller eclipses- http://adsabs.harvard.edu/abs/2013A%26A...554A.110P
