A V star

From Wikipedia, the free encyclopedia

An A V star is a main sequence (hydrogen-burning) star of spectral type A and luminosity class V. These stars have spectra which are defined by strong hydrogen absorption lines.[1] They have masses from 1.4 to 2.1 times the mass of the Sun and surface temperatures between 7,600 and 10,000 K.[2], Tables VII and VIII. Examples include Sirius A and Vega.[3]
