Resum

Four gamma-ray binaries, namely PSR B1259-63, HESS J0632+057, HD 215227 
and LSI+61 303, contain compact objects orbiting around massive Be 
stars. The nature of the compact object is only known in the case of PSR 
B1259-63, but the other systems could also contain young non-accreting 
pulsars with relativistic winds. Around periastron passage the compact 
objects should produce significant changes in the structure of the Be 
disks due to gravitational forces and eventually by ram pressure from 
the pulsar wind. Accurate photometry could be used to constrain the 
shape of the disk during the periastron passage. In this talk I present 
an ongoing program to monitor the optical photometry of gamma-ray 
binaries and show preliminary results for the case of LS I+61 303. I 
will also briefly talk about my work here, related with relativistic 
hydrodynamic simulations of these systems.
