Accretion disks: How the wind blowsNo Abstract available for this article.doi:10.1038/305666b0Abramowicz, MarekBath, GeoffreyNature Publishing Group UKNature
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...
small disks with the same mass allow more efficient gas accretion onto already formed planetary cores, leading to more massive gas giants. Given the right conditions, high viscosity (α= 10−3) leads to more massive cores (compared toα= 10−4) and it also enhances gas accretion. At th...

"We started to think that real disks may not actually exist around the most massive forming stars, and that those stars might have to form in a different way," said Dr Johnston. "Maybe the accretion into an O-type star was much more chaotic and dynamic than for the birth of our Sun....
is gravitationally attracted towards the black hole, creating an ‘accretion disk’, which emits the strong X-rays that we observe. These systems with a black hole and a massive star are called ‘high-mass X-ray binaries’ and have been very helpful in understanding the nature of ...
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 ...
Stellar winds from the companion star, HDE 226868, blow material onto the accretion disk surrounding the black hole. As this material falls into the black hole, it emits X-rays. X-ray image of Cygnus X-1 taken from orbiting Chandra X-ray Observatory Photo courtesy NASA/CXC In addition ...
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-...
