  Apart from thousands of `regular' exoplanet candidates, Kepler satellite has
discovered a few stars exhibiting peculiar eclipse-like events. They are most
probably caused by disintegrating bodies transiting in front of the star.
However, the nature of the bodies and obscuration events, such as those
observed in KIC8462852, remain mysterious. A swarm of comets or artificial
alien mega-structures have been proposed as an explanation for the latter
object.
  We explore the possibility that such eclipses are caused by the dust clouds
associated with massive parent bodies orbiting the host star.
  We assumed a massive object and a simple model of the dust cloud surrounding
the object. Then, we used the numerical integration to simulate the evolution
of the cloud, its parent body, and resulting light-curves as they orbit and
transit the star.
  We found that it is possible to reproduce the basic features in the
light-curve of KIC8462852 with only four objects enshrouded in dust clouds. The
fact that they are all on similar orbits and that such models require only a
handful of free parameters provides additional support for this hypothesis.
  This model provides an alternative to the comet scenario. With such physical
models at hand, at present, there is no need to invoke alien mega-structures
for an explanation of these light-curves.
