| definition | Stars of spectral type A in which lines of ionized metals and rare-earth elements are abnormally enhanced. Such stars have unusually strong magnetic fields, thousands of times stronger than the Sun's typical surface field. Ap stars are generally slow rotators because of magnetic braking. | |||||||||||||||||||||
