A-type star
(A)
(star with spectral characteristics of around 8500K)
An A-type star is a star in the A-class, a
spectral class indicating stars with a temperature
in the general range of 8500K,
applicable to main sequence stars of around 2 solar masses
and 2 times solar radius.
Such main sequence stars
burn their hydrogen in a few hundred million years
and have strong hydrogen absorption lines.
