Description
The Eddington mission has two primary scientific goals: the study of
stellar structure and evolution, and the search of habitable planets.
The first one, based on asteroseismology techniques, is our interest.
The goal here is to measure oscillations frequencies for as many modes
as possible for a sample of stars whose masses, ages and chemical
compositions are close to the Sun's. In this way we will also have a
measure of the Sun's evolution. Among this sample we want also to
include binary stars of large period so we can have an independent and
precise measurement of radii and masses. For the moment, we have started
to test whether data from the OMC (Optical Monitor Camera) on board
INTEGRAL (International Gamma-ray Astrophysics Laboratory) are suitable
for asteroseismology studies. Analysis of this data, in progress now,
will be useful to develop methodology and software to be later used in
the analysis of Eddington data. Preliminary results of this exploration
will be presented, keeping in mind that this data will, obviously, only
provide a glimpse of what can be obtained using Eddington.
