Show that there can be intensive evolution of structure of the gaseous disk. Secular evolution of the disk shows interesting characteristics: (1) high viscosity excited by snexp can efficiently transport the gas from 10 kpc to ∼1 kpc forming a stellar disk whereas a stellar ring forms for the case with low viscosity; (2) starbursts trigger.

Both cool atomic hydrogen (hi) and warm molecular hydrogen (hii) make up most of the disc's gaseous component. This gas serves as the fuel for the formation of new stars in the disc.

The stellar disc of the milky way is assumed to follow an exponential surface.
An alternate scenario involves the formation of the stellar disk from an initially thick, clumpy disk of gas that gradually settled. The oldest stars would then have formed while the gas disk was still in a puffed up and disordered configuration.
Swirling in orbit of young stars (or protostars) are massive disks of dust and gas called circumstellar disks. These disks are dense enough to be opaque hiding young solar systems from visible.

To understand galactic structure, morphology, and evolution, a key question is what regulates the star formation rate.
Objects that form out of a disk around a star, in which case post main sequence evolution: the formation of a red giant densities the gas is degenerate.
The interaction of stars with clouds of interstellar gas can reduce this time by se veral orders of magnitude [17]. At the current age of the galaxy the structure of the stellar disk is determined to a considerable e xtent precisely by this relatively efficient process.
Accretion disk begins to heat up from the pressure of the gas particles, and, one day, thermonuclear reactions start in its core. Two hydrogen atoms are squeezed together with such pressure and heat that they fuse into one atom of helium, thus liberating considerable [footnote 1]this energy is what drives the stars.
Today with the aid of state-of-the-art technologies, cosmologists have recorded stellar evolution in chapter and verse. Nebula the orion nebula: the orion nebula is a picture book of star formation, from the massive, young stars to the pillars of dense gas that may be the homes of budding stars.

The observed disk warp and the steep surface density distribution favor in situ star formation in gaseous accretion disks as the origin of the young stars.
This thesis studies many aspects of gas evolution in disk galaxies. A simple, effective method is developed for initializing a three-dimensional gaseous disk which isin detailed equilibrium. With this method, theo-retical predictions for disk stability and swing amplificat ion are numerically studied for three-dimensional disks.
As the molecular gas clouds condense, they form the earliest versions of a star, called a protostar.
Galaxies come in a bewildering variety of shapes and sites, but a large majority - perhaps 80% - possess a disk of some kind. Galactic disks are thin, basically circular distributions of stars, gas, and dust; this material moves on nearly circular orbits about a common center.
The exact definition of the galaxy’s disk depends on what objects we use to define it, and it has no sharp boundary. The hottest young stars and their associated gas and dust clouds are mostly in a region about 300 light-years thick. Older stars define a thicker disk that is about 3000 light-years thick.
Galaxy’s disk previously detected by the galaxy evolution explorer satellite. With its highly warped hi gaseous disk (∼20 ), m63 represents one of the several examples of an isolated spiral galaxy with a warped disk showing recently discovered strong evidence of an ongoing minor merger.

The gas will eventually be pushed away from the stars to leave a star cluster. The first stars in our galaxy are the globular star clusters orbiting outside the stellar disk which contains the spiral arms.
This book focuses on the stellar disk evolution and gas disk turbulence of the most numerous galaxies in the local universe – the dwarf galaxies. The “outside-in” disk shrinking mode was established for a relatively large sample of dwarf galaxies for the first time, and this is in contrast to the “inside-out” disk growth mode found.

The evolution of the star-disk system and the disk chemical composition determines the initial conditions for planet formation. Therefore a comprehensive understanding of the main physical and chemical processes in disks is crucial for our understanding of planet formation.

Or abrupt changes in chemistry can cause a gap that also mimics the action of a planet. A solar system’s snow line, for example, marks the boundary between the hot inner disk, where water exists as vapor, and the outer disk, where water freezes into solid grains. Similar transitions occur for other compounds, like carbon monoxide and ammonia.
Over time, the gas disk would have settled into a thinner configuration with more ordered motion, and the youngest stars then would have formed with the disk in a more ordered configuration.
From stellar mass accretion and stellar jets and outflows, to the evolution of gas and dust in protoplanetary and transitional disks, these studies can shed light on the conditions for planet formation. Also of interest are the planet-disk interactions, triggering planet migration and affecting the dynamical evolution of the young planetary.
Stellar disk recently formed from the gaseous disk as a conse-quence of a gas-rich minor merger, we expect that such a newly formed disk is characterized by a low velocity dispersion and a flattening which should be similar to those of the gaseous disk. On the contrary, an older stellar disk should be thicker and have.
