Star Data

A lot of the technical data on this page was taken from documentation accompanying the freeware program Star by Aina Rasolomalala. For more information and to get your own copy of this software go to the acknowledgements page.

Star types range through a variety of spectral types using the codes O B A F G K M. These letters indicate in descending order the temperature of the stars. (A mnemonic for remembering this sequence is 'Oh, Be A Fine Girl, Kiss Me').

Galactic Phenomena:

Black holes: A collapsed star that has such a strong field of gravity that even light can't escape its grasp.
Ion storms: Intense amounts of electromagnetic radiation.
Nebula: Dust clouds.
Pulsar: Produce powerful gravity waves.
Space rifts: A wormhole that connects to a stellar system from a far away galaxy.
Quasars: Quasars emit powerful radio waves.

The spectral type for stars is usually further specified by a decimal classification (using the digits 0 to 9). Thus a type F1 star is one-tenth of the way between F and G. All stars are treated this way with the exception of dwarf stars, which do not have decimal classification.
