Query: Light-curve analysis of KOI 2700b: the second extrasolar planet with a
  comet-like tail   The Kepler object KOI 2700b (KIC 8639908b) was discovered recently as the
second exoplanet with a comet-like tail. It exhibits a distinctly asymmetric
transit profile, likely indicative of the emission of dusty effluents and
reminiscent of KIC 12557548b, the first exoplanet with a comet-like tail.The
scientific goal of this work is to verify the disintegrating-planet scenario of
KOI 2700b by modeling its light curve and to put constraints on various tail
and planet properties, as was done in the case of KIC 12557548b. We obtained
the phase-folded and binned transit light curve of KOI 2700b, which we
subsequently iteratively modeled using the radiative-transfer code SHELLSPEC.
We modeled the comet-like tail as part of a ring around the parent star and we
also included the solid body of the planet in the model. During the modeling we
applied selected species and dust particle sizes. We confirmed the
disintegrating-planet scenario of KOI 2700b. Furthermore, via modeling, we
derived some interesting features of KOI 2700b and its comet-like tail.
