吸积盘不仅仅是气体和尘埃 Accretion disks are not just gas and dust. 黑洞会把所有东西都拖进去 Black holes will drag in anything and everything. 有恒星有气体 There are stars. Theres gas. 气体云中,有恒星正在形成 Theres gas clouds. Theres stars in formation. 也有恒星正在死亡 There are stars ...
Around the black hole is an accretion disk of rapidly spinning gas that's surrounded by a torus (a donut-shaped disk of gas and dust). As the material from the accretion disk falls into the area around the black hole (the event horizon), it heats to millions of degrees Kelvin and is...

Black holes in this situation will often be encircled by an accretion disk, a ring of hot, luminous gas with transitory bright spots similar to solar flares. Even if a black hole resides by itself in a dark corner of the universe, it gives off strong bursts of radiation that your ship'...
In the biggest black holes, Levin adds, “you might be able to make it for a year before you are ultimately demolished in the center.” Next, avoid black holes with accretion disks. About 1 percent of supermassive black holes accumulate these fast-spinning rings of matter. They can heat ...
And supermassive black holes have accretion disks that emit so much energy that astronomers can detect and even photograph them. But IBHs, in the midrange between those two other types, are far more difficult to detect. There are a handful of objects in space that astronomers suspect might be...
This is a very short lifetime for the accretion disk used to explain the origin of the planets in our solar system. In 1999, studies showed T Tauri stars contained perhaps 332-333 earth masses in their *protoplanetary disks*, The Leonard Award Address: On the Difficulties of Making Earth-...
parade: first they simulated more than 10,000 model disks with different properties. They then compared these images and spectra with the data obtained from nature. The best agreement was for a stable disk, where the gravitational effects of both the star and the disk material are important. ...
This means that mm-sized chondrule aggregates can grow on a timescale much smaller than the disk accretion timescale ($\\sim$$10^6 - 10^7$ years). Our results suggest a pathway from the mm-sized grains found in primitive meteorites to fully formed asteroids. We speculate that asteroids...
