abstract = "An exoplanet, or extrasolar planet, is a planet that does not
orbit the Sun, but is around a different star, stellar remnant, or
brown dwarf. Up to now, about 1900 exoplanets were discovered. To
better understand the dynamics of these exoplanets, a study with
respect to possible collisions of the planet with the central star
is shown here. We present an expanded model in a small parameter
that takes into account up to the fifth order to analyze the
effect of this potential in the orbital elements of the extrasolar
planet. Numerical simulations were also performed using the N-body
simulations, using the software Mercury, to compare the results
with the ones obtained by the analytical model. The numerical
simulations are presented in two stages: one considering the
celestial bodies as point masses and the other one taking into
account their dimensions. This analysis showed that the planet
collided with the central star in the moment of the first
inversion for orbits with high inclinations in various situations.
The results of the simulations of the equations developed in this
study are consistent with the N-body numerical simulations. We
analyze also the flip of the inclination taking into account the
coupling of the perturbations of the third body, effect due to the
precession of periastron and the tide effect. In general, we find
that such perturbations combined delay the time of first
inversion, but do not keep the planet in a prograde or retrograde
orbit.",
