English

Subject field(s)
  • Astrophysics and Cosmography
  • The Stars (Astronomy)
DEF

The steady stream of matter ejected from many types of stars, including the sun ...

OBS

Plasma ejected at varying rates from a star's surface into interstellar space.

OBS

Although the mass loss is small in sunlike stars, it has been found to be very considerable in red giants and in hot luminous ultraviolet stars. This large mass loss could have a substantial effect on the final evolution of the stars.

OBS

Conceptual family: solar wind.

DEF

[...] flux continu de particules s’échappant de l’atmosphère de certaines étoiles chaudes et massives[,] à l’origine d’une importante perte de masse de ces étoiles au cours de leur vie.

CONT

Pendant toute la période de combustion d’hydrogène(ce qu'on appelle la séquence principale), les étoiles plus massives que 15 masses solaires subissent une perte de masse par un vent stellaire engendré probablement par la pression de radiation. [...] Ces pertes de matière ont des répercussions considérables sur l'évolution [...]

Subject field(s)
  • Astronomy
  • Astrophysics and Cosmography
  • The Stars (Astronomy)
DEF

The principal sequence of stars on the Hertzsprung-Russell diagram, running diagonally from upper left (high temperature, high luminosity) to lower right (low temperature, low luminosity) and containing about 90% of all known stars.

CONT

A star spends most of its life on the main sequence.

French

Domaine(s)
  • Astronomie
  • Astrophysique et cosmographie
  • Étoiles (Astronomie)
CONT

Le diagramme de Hertzsprung-Russell montre la luminosité des étoiles en fonction de leur couleur ou de leur température.(...) La plupart des étoiles sont situées sur la séquence principale. Pendant la première phase de son évolution, c'est-à-dire pendant la combustion d’hydrogène, l'étoile parcourt la séquence principale de gauche à droite. Puis, pendant la combustion d’hélium, l'étoile se dirige vers la droite, gonfle énormément et devient une géante(ou supergéante) rouge(...)
