Français : Vue d'artiste montrant un système de deux étoiles, une naine blanche au premier plan et son compagnon en arrière-plan. La naine blanche aspire du gaz de son compagnon, qui est canalisé vers ses pôles. Lorsque ce matériau tombe sur la surface chaude de la naine blanche, il déclenche à l'un de ses pôles une explosion de type micronova. |

JPEG file comment | R126 (also known as HD 37974) is a hypergiant blue variable star in the Large Magellanic Cloud, with unusual features in its spectrum. These features indicate that this massive star – seventy times the mass of the Sun and trillions of times more luminous – is surrounded by a dusty disc. Such discs were thought unlikely around hot stars but R126 shares this trait with another blue giant, HD 268835. The disc is thought to be around 60 times the diameter of the orbit of Pluto – some 0.3 trillion kilometres – but it is not know if the disc contains newly forming planets or is merely a relic from an earlier period of planet formation. |
