Complete the attached questions for homework (also Word document attached) La vie d’une étoile (pages 468-471) 1.    Explique ce qu’est l’attraction universelle. 2.    Qu’est-ce qu’est une nébuleuse? 3.    Explique comment une nébuleuse se transforme en étoile (3 étapes). 4.    Qu’est-ce qui arrive quand l’étoile a consommé tous les combustibles nécessaires à la production d’énergie? 5.    Qu’est-ce qu’est une supernova?  Durant cette phase qu’est-ce qui arrive au cœur de l’étoile?      ** Lorsque notre Soleil gonflera et se transformera en géante rouge, ses couches externes grossiront.  Ses dimensions seront alors multipliées par 100 et il engloutira Mercure, Vénus, la Terre et peut-être même Mars. 6.    Qu’est-ce qu’est une étoile à neutrons? 7.    Qu’est-ce qu’est un pulsar? 8.    Quel type d’étoile peut éventuellement se transformer en trou noir? 9.    Qu’est-ce qu’est un trou noir?      ** Le terme « trou » porte à confusion parce qu’il laisse entendre qu’il n’y a là que le néant.  En réalité, c’est une énorme quantité de matière comprimée en une sphère de quelques kilomètres de diamètre.  Sa densité est telle que la masse d’un trou noir gros comme le poing équivaudrait à la masse d’environ 10 milliards d’automobile. 10.                       Décris l’évolution d’une étoile de faible masse et celle d’une étoile qui possède 10 fois la masse du Soleil. 11.                       Explique les termes géantes rouges, supergéantes rouges et naine blanche. 12.                       Explique comment une étoile évolue de la maturité à la mort.               **Familiarise-toi avec la figure 2 de la page 469
