So this theory suggests that large planets, the gas giants, uh, they develop from large clumps of mostly gas and some dust in an accretion disk.Outer regions of an accretion disk can be unstable, gravitationally unstable, which is what causes these clumps to form, and in some cases, grow...
accretion, accretion disksbinaries: closestars: individual: 4U 0614+091stars: neutronX-rays: binariesX-rays: burstsThe low-mass X-ray binary 4U0614+091 is a source of sporadic thermonuclear (typeI) X-ray bursts. We find bursts with a wide variety of characteristics in serendipitous wide-...
Now, think of it is two parts: an inner accretion disk, and an outer accretion disk. In the inner part, once an object gets large enough, that objects gravitational field gets stronger, which speeds up the accretion process. You know, larger objects attract smaller ones and sort of gobble...
This is the puzzling notion that the Jovian-like planets are common despite the possibility that the gas and the dust involved in their formation may not have lasted long enough for them to form under the core accretion model. Time Travel Team: That is indeed a problem. Uh, so, should ...

How big is a gravitational singularity? What is accretion of planetesimals? What do the variables in the nebular hypothesis mean? What is gravitational time dilation? What is hydrostatic equilibrium in astronomy and astrophysics? Why is the gravitational force zero at the center of the Earth?
This artist’s impression depicts a rapidly spinning supermassive black hole surrounded by an accretion disc. Credit: ESA/Hubble, ESO, M. Kornmesse Origin of Theory: Singularities were first predicated as a result of Einstein’sTheory of General Relativity, which resulted in the theoretical existenc...
star, fusing hydrogen into helium. Which, purely based on high volumetric density of pure awesome, I'm going to call a thing. An accretion disk around a quasar could be light days across, extending well past the orbit of Pluto and killing us all, if you dumped it in our Solar System....
<italic>Context. </italic>The role of low ionization nuclear emission region (LINER) galaxies within the picture of active galactic nuclei (AGN) has been controversial. It is still not clear whether they host an AGN in a low accretion mode or whether the
