. Previous . Next . A GiST index is a template indexing structure that allows domain experts to adhere to an interface and index custom data types. Must implement the following methods- consistent, union, compress, decompress, penalty, picksplit, same. Writes to GiST indexes lock the whole index. Writes to btree indexes only lock the affected index page. Knowledge of C is required to write custom GiST indexes.

Dust and debris parade in an extremely misshapen ring around the young star, HD 15115. The disk, seen edge-on with NASA's Hubble Space Telescope, is the dense blue line extending from the star to the upper right and lower left of the image. The disk appears thicker at upper right than at lower left, evidence of its lopsided structure. Astronomers think the disk's needle-like look is caused by dust particles following a highly elliptical orbit around the star. ...

... These trajectories have an initial flight from the Earth to a large distance (of about 1.5 million km), the following passive flight to the Moon's orbit, an approach to the Moon with a decrease of an energy of a particle (spacecraft) selenocentric motion to a negative value and the temporary capture in an elliptic orbit of the Moon's satellite. ... Several trajectories of this type are determined. ... Ivashkin V. V. On optimal trajectories of space flight to the Moon in the Earth--Moon--Sun system. ...
