Descripción
Oscillations of the Sun have been used to understand its interior
structure. The extension of similar studies to more distant stars has
raised many difficulties despite the strong efforts of the international
community over the past decades. The CoRoT (Convection Rotation and
Planetary Transits) satellite, launched in December 2006, has now
measured oscillations and the stellar granulation signature in three
main sequence stars that are noticeably hotter than the sun. The
oscillation amplitudes are about 1.5 times as large as those in the Sun;
the stellar granulation is up to three times as high. The stellar
amplitudes are about 25% below the theoretic values, providing a
measurement of the nonadiabaticity of the process ruling the
oscillations in the outer layers of the stars.
