Achernar

I chose this star because of the top 10 brightest, it has a rapid rotation velocity, causing it to become oblate in shape rather than spherical which is peculiar. Is the last out of the brightest stars, but it is also most blue and hottest out of all of them. It is in the constellation Eridanus and has a rapid rotation velocity, causing it to become oblate in shape rather than spherical.
