Variable starWhat is Salm
Salm, tau Pegasi, is a white variable 162 light-years away, pulsing on hourly scales. Her name comes from Arabic and has been associated with the idea of leather or hide: an echo of the Arab inventories of the sky, in which every glimmer received a concrete name even when the star itself was modest. Her light departed when Beethoven was premiering his third symphony.
