Detection of
exoplanets by gravitational microlensing
Sedighe Sajadian- SUT
Abstract:
In
recent years a large number of
planets with very small period named
as Hot Jupiters, are detected around
the stars with the methods of
transit and Doppler effect. In this
work we have investigated
illuminating Hot Jupiters by caustic
crossing. It seems that effect of
Hot Jupiters is illuminated near
peak of magnification of its host
star in infrared band. Detection by
caustic crossing is direct detection
method and it is useful in studding
of atmospheres of Hot Jupiters. We
plotted the light curve of Hot
Jupiters when crosses the caustic
and performed Monte Carlo simulation
for studding the probability of this
phenomenon. At last we investigated
effects of all (physical and
geometrical) parameters in the
program, on efficiency.
