The resonant frequency of a disk shape resonator is obtained by solving the following equation:

The HD 142527 disk isn't the first to defy the standard disk shape. A doughnut-shaped disk appears to surround a pair of stars that lie in the constellation Taurus.

The drops assumed a variety of symmetrical shapes as they oscillated between a disk shape and a cigar shape.

Usually, the butterfly lappets are made having a disk shape symmetric with respect to the longitudinal plan, with constant thickness and rounded edges (fig.

During the past decade or so, several researchers have speculated that the young Milky Way may have taken as long as 3 billion years to collapse from a spherical cloud of gas into its present disk shape. This contrasts with a standard theory proposed in 1962, which calculates the collapse time at 1 billion years.

The material could be in the form of tiny dust grains, perhaps flowing out from the star itself or else in a disk shape that some researchers believe could be a planetary system in the early stages of its formation.

Knead lightly then divide in two, flatten to disk shapes,wrap in cling film and chill for 30 mins.
