Subject field(s)
  • The Stars (Astronomy)
CONT

A young star is apparently blasting high-speed gas jets from its poles, carving a void through the dense molecular cloud that was its birthplace, according to an international team of astronomers. ... The timing of stellar birth phases depends a lot on the star's environment. If a star has nearby companion stars, or if it starts forming planets in its disk, these objects can clear away gas that feeds the jets, terminating them more quickly than an isolated star without planets.

CONT

Beta Pictoris, jeune étoile de magnitude 4 émettant beaucoup dans l'IR [infrarouge]. Elle est entourée d'un disque de matière qui devrait donner naissance à une ou plusieurs planètes, avec le temps.
