Description
Dans le système solaire, la composition du plasma solaire est identique à celle de la couronne solaire : 73 % d'hydrogène et 25 % d'hélium. Le Soleil perd environ 1 × 109 kg de matière par seconde, soit un téragramme, sous forme de vent solaire. Dans la couronne surchauffée du soleil (1 million de degrés) des atomes d'hydrogène sont ionisés, ce qui leur confère une charge électrique.
Ce plasma brûlant est ensuite expulsé à une vitesse considérable. La vitesse du vent solaire varie de 400 à 800 km/s (de 1 440 000 à 2 880 000 km/h), la moyenne étant de 450 km/s (1 620 000 km/h). Les écoulements de vent solaire sont dits rapides dans les trous coronaux, généralement situés au niveau des pôles où les lignes de champ magnétique sont ouvertes. A contrario, les écoulements de vent solaire sont dit lents au niveau du plan équatorial.
Le vent solaire étant un plasma, il subit l'influence du champ magnétique solaire. À cause de la combinaison du mouvement radial des particules et de la rotation du Soleil, les lignes de champ magnétique solaires forment une spirale (la spirale de Parker). Le vent solaire, entraîné par les lignes de champ magnétique, épouse la forme de cette dernière.
In the solar system, the composition of solar plasma is identical to that of the solar crown: 73% of hydrogen and 25% of helium. The Sun loses approximately 1 × 109 kg of matter a second, that is to say a 'téragramme', in the form of solar wind. In the overheated crown of the sun (1 million degrees) of the atoms of hydrogen are ionized, which confers an electric charge to them. This extreme plasma is then expelled at a considerable speed. The speed of the solar wind varies from 400 to 800 km/s (from 1.440.000 to 2.880.000 km/h), the average being of 450 km/s (1 620.000 km/h). The flows of solar wind are known as rapids in the crowned holes, generally located at the level of the poles where the lines of magnetic field are open. At opposite, the flows of solar wind are known as slow on the level of the equatorial plan. The solar wind being a plasma, it undergoes the influence solar magnetic field. Because of the combination of the radial movement of the particles and rotation of the Sun, the solar lines of magnetic field form a spiral (the spiral of Parker). The solar wind, pulled by the lines of magnetic field, marries the form of the latter.
