Resumen:
In June of 2011 we started a continuous photometric monitoring of
transiting planets host stars in the southern hemisphere, with the aim
of searching for periodic variations in their mid-transit times. Such
variations (or TTVs) are produced by the gravitational action of other
bodies in the system that disturb the semimajor axis and therefore the
orbital period of the transiting planet. The smaller the mass of the
disturber the lower the amplitude of the variation and therefore high
precision (tens of seconds) is required to measure the central transit
times. In this paper, we present a full analysis of TTVs of some of the
objects with transits observed from 2011 to the present.
