Resumen:
Over the last 5 years, Cassini magnetic field and plasma observations in
the vicinity of Titan have revealed that the properties of the
moons plasma environment are strongly influenced by the dynamics
of Saturns equatorial magnetodisk. As the magnetodisk flaps past
Titans orbit in response to changes in solar wind dynamic
pressure and Saturn kilometric radiation phase, the pressure inventory
of the flow ahead of the moon varies with implications on its
atmopsheric escape. In this work we identify some basic properties of
Titans induced magnetosphere (size, shape) and, in sectors where
upstream conditions are less variable, we compare the importance of the
different pressure terms (magnetic, dynamic, thermal) at different
altitudes to study the pressure balance.
