English

Subject field(s)
  • Astrophysics and Cosmography
DEF

That branch of astrophysics studying the wave motions inside the Sun.

French

Domaine(s)
  • Astrophysique et cosmographie
DEF

Astrosismologie du Soleil, qui étudie notamment le mode d'oscillation de pression et de gravité de la matière solaire.

CONT

L'autre grand et nouveau dada des astrophysiciens s'appelle «hélioséismologie» - en quelque sorte, l'étude des séismes qui agitent le Soleil.

Record 2 2009-05-07

English

Subject field(s)
  • Astrophysics and Cosmography
  • Space Physics
DEF

The study and measurement of acoustic vibrations in stars in order to learn more about stellar structure and evolution.

CONT

Astroseismology, an outgrowth of helioseismology, had to await the development of instruments capable of detecting radial(up and down) movements in a star's surface of a few meters per second over distances measured in light-years. Such instruments are now available and are also used to search for extrasolar planets.

French

Domaine(s)
  • Astrophysique et cosmographie
  • Physique spatiale
DEF

Étude des phénomènes vibratoires observés à l'échelle d'un astre, permettant d'approfondir la connaissance de sa structure et de sa dynamique internes.

OBS

L'astrosismologie recouvre à la fois la sismologie des planètes et la sismologie stellaire. On rencontre parfois le terme «astérosismologie», qui est déconseillé.

Record 3 2002-11-25

English

Subject field(s)
  • Facilities and Instruments (Astronomy)
  • The Sun (Astronomy)
CONT

When... DISCO [Dual Irradiance and Solar Constant Observations] was not selected as a mission, the helioseismology instruments, the total solar irradiance and the in situ solar-wind measurements were taken over by a new solar mission just starting an assessment study. The Solar High Resolution Observatory(SOHO) for the study of the corona then became the Solar and Heliospheric Observatory.
