The clouds of captured hydrogen and helium gas contracted, spun up, flattened, and deposited gas onto the surface of each giant protoplanet, while solid bodies within that
disk accreted into the giant planet's regular moons.
disk is expected to have dissipated long before a gas giant could have formed.
The evidence of a thick debris
disk increases the likelihood that one or more rocky planets orbit the star, however, even if it suggests a high bombardment scenario.
The existence of an accretion
disk caused by mass transfer between the two components of the system may give rise to polar jets, which would interact with previously ejected material.
Cat's Eye Nebula
The galaxy was well fitted by an exponential
disk with an ellipticity of 0.70 ± 0.07.
The gravitational influence of Proxima may also have stirred up the Alpha Centauri protoplanetary
The infall of matter into the new black hole produces an accretion
disk and releases a burst of energy, analogous to the collapsar model.
The national flag of Japan is a white rectangular flag with a large red
disk (representing the sun) in the center.

The viral genome is associated with proteins within a central
disk structure known as a nucleoid.
The white dwarf luminosity function can therefore be used to find the time when stars started to form in a region; an estimate for the age of the Galactic
disk found in this way is 8 billion years.
Therefore, the most favorable model of its formation is a slow accretion in the low-density Jovian subnebula—a
disk of the gas and dust that existed around Jupiter after its formation.
They determined that the temperature ranged from −68 °C (−90 °F) at the pole up to 7 °C (45 °F) at the midpoint of the
disk (corresponding to the equator).
History of Mars observation
This high abundance remains unexplained and may have been caused by an early and rapid buildup of planetesimals—small, subplanetary bodies—before the presolar
disk began to heat up.
This moon, like all moons of Uranus, probably formed from an accretion
disk that surrounded the planet just after its formation.
This provided a convenient method for software to be installed onto the PowerBook or transferred to the desktop, without the need for the 100's optional floppy
This tool however does not address situations where the game has been installed on a PC which uses more than one user account as it only works once per PC (unlike activations which are counted per user-account), nor is it able to revoke an activation if the installation has become unusable, for example by hard
disk failure, effectively rendering such activations permanently lost.
This was hypothesized as either a perturbation of the dust
disk by a planet or else an orbiting object that was surrounded by dust.
Those synthetic diamond windows are shaped as
disks of large diameters (about 10 cm for gyrotrons) and small thicknesses (to reduce absorption) and can only be produced with the CVD technique.
Viewed from Earth, the Moon is just far enough away to have very nearly the same apparent-sized
disk as the Sun.
When the protostar has grown such that it ignites to form a star, the surviving
disk is removed from the inside outward by photoevaporation, the solar wind, Poynting–Robertson drag and other effects.
While early incense seals were made of wood or stone, the Chinese gradually introduced
disks made of metal, most likely beginning during the Song dynasty.
