Boss' new model demonstrates how a phase of marginal gravitational instability
in the gas disk surrounding a proto-sun, leading to an outburst phase, can explain all of these findings.
In the gravitational instability
model, some of the gas and dust suddenly clumps and collapses, simultaneously creating a planet's core and atmosphere.
There has been considerable uncertainty about how systems of planets form, with two leading models, called core accretion and gravitational instability
Much theoretical effort has gone in to understanding the gravitational collapse of protostar but the question of gravitational instability
of partially-ionized gaseous medium in the presence of radiative heat-loss function is of particular interest in cosmogony.
This theorem is applicable exactly to the case of the gravitational instability
of the cosmic clouds.
Further, the gravitational instability
of oceanic islands indicates that collapses could imperil major cities bordering the ocean basins (McGuire, 1996).
Dynamics of stellar disks (including the equilibrium of the axisymmetric disc, dynamics of perturbations in the disc plane, physics of gravitational instability
, the conditions of gravitational stability of the disc, stability of stellar disks in relation to the bending perturbations);
There has been uncertainty about how planets in other solar systems formed, with two leading models, called core accretion and gravitational instability
In contrast, Nayakshin begins with the giant blob of gas generated by gravitational instability
formed galaxies and their clusters whose high temperatures make them observable using X-rays.
It is thought that these short bursts of mass accretion are driven by marginal gravitational instability
in the gas disk.
In the competing model, called gravitational instability
, a planet forms wholesale when a cloud of gas, ice, and dust breaks into clumps.
