Blanet: A new class of planet that could form around black holes

Post by fred8615 »

Supermassive black holes are among the most exciting and puzzling objects in the universe. These are the giant, massive bodies that sit at the heart of most, perhaps all, galaxies. Indeed, they may be the seeds from which all galaxies grow.

Supermassive black holes are at least a hundred thousand times the mass of our Sun. They are often surrounded by thick clouds of gas that radiate vast amounts of energy. When this happens, they are called active galactic nuclei. Discovering the properties of these clouds, and their curious central residents, is an ongoing exercise for astrophysicists.

Now researchers have a new phenomenon to consider — the idea that planets can form in the massive clouds of dust and gas around supermassive black holes. Last year, Keichi Wada at Kagoshima University in Japan, and a couple of colleagues showed that under certain conditions planets ought to form in these clouds. These black hole planets, or blanets as the team call them, would be quite unlike any conventional planet and raise the possibility of an entirely new class of objects for astronomers to dream about.
