WebJ1407b ain't no regular planet, it's a brown dwarf, and its ring game is off the hook. The way those rings look is more like a protoplanetary disk than a regular ring system, and it's orbit is whack, like it might not even be orbiting anything steady. It's crazy cool to study stuff like J1407b because it helps us learn more about how planets ...

A protoplanetary disk is a rotating circumstellar disc of dense gas and dust surrounding a young newly formed star, a T Tauri star, or Herbig Ae/Be star. The protoplanetary disk may also be considered an accretion disk for the star itself, because gases or other material may be falling from the inner … See more Protostars form from molecular clouds consisting primarily of molecular hydrogen. When a portion of a molecular cloud reaches a critical size, mass, or density, it begins to collapse under its own gravity. As this collapsing … See more Gas-poor disks of circumstellar dust have been found around many nearby stars—most of which have ages in the range of ~10 million … See more • Accretion disk • Circumplanetary disk – Accumulation of matter around a planet • Debris disk • Disrupted planet • Formation and evolution of the Solar System See more The nebular hypothesis of solar system formation describes how protoplanetary disks are thought to evolve into planetary systems.

WebSince we are interested in studying the capability of the disk to form planets, we have selected the model that fits the data with the highest allowed value for the viscosity parameter, which gives the lowest disk mass (9 MJ ). As we show in §4, even this low-mass disk is capable to form a planetary system. WebMar 11, 2011 · Protoplanetary disks are generally composed of gas and dust particles.
