The You will find here a lexique of the terms used in the SWG Pages,
which received a specific definition in the Corot Project.
central program: Mainly related to
the long runs which are intended to provide a unique precision in the measurement
of the oscillation frequencies as well as a unique acces to time scales
of the order of a few months. Through the central program, we propose to
tackle very fine structure of the stars and constraint our understanding
and description of several of the key-mechanisms at work in stellar interiors
evolution.
core program: the Corot Core
program corresponds to the scientific main issues Corot is intended to
address. They mostly concern transport mechanisms in stars around main
sequence phase. Solar-like oscillators as well as A-type classical
pulsators (delta Scuti and related objects) have been selected as favorite
targets for this purpose. The Core program is decomposed in the central
Program and the exploratory program.
exploratory program: In
parallel of the central program which will be lead on a restricted set
of objects. The Corot exploratory program proposes to use objects observed
during short runs and selected secondary targets of long runs to map the
HR diagram and improve our understanding of the pulsation behavior of stars
across the HR diagram.
long runs: 150 days runs. The mission
profile contain 5 to 6 long runs.
Primary target: Non giant stars of
spectral type F or G, with 4.5<mv<6, or known delta Scuti stars
with 4.5<mv<9. These objects are considered to allow an optimal use
of the instrumental performances in terms of seismology of solar-like
pulsators and delta Scuti stars and related objects. These objects were
all listed by the Ground Based Working Group and were used in the first
phase of selection as priority candidates for the long runs of the Corot
mission.
Secondary targets: Each run will allow
the observation of 10 objects in the Seismology field. For the long runs,
the basic idea is that each field will be selected according to one
Primary target and to 9 other objects selected for their interest in terms
of seismology. These 9 supplementary objects are named secondary targets.
seismology field:
The focal plane of the instrument is separated
in two equal areas:, each of them corresponding to a 1.3degree by 2.7 degrees
collecting surface. One is mostly devoted to the seismology Program
and the other to the exoplanet search program.
short runs: 10 days to 20 days runs.
The mission profile should allow 5 to 6 of them.
