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
