A V star

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. [ [http://hyperphysics.phy-astr.gsu.edu/hbase/starlog/staspe.html Stellar Spectral Types] , entry at hyperphysics.phy-astr.gsu.edu, accessed on line June 19, 2007.] 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.
