class b stars

Hi, 

Could anyone point me in the direction of finding 
out some information on class b stars?I'm working 
on a project for an astrophysics class modeling a 
star, and mine turned out to be a Class B.  It's 4.5 
solar masses, 19153.6 K, and the luminosity is about
519 L_solar.  I'd like to find an actual star that 
is at least very similar to this and compare it to 
the sun and other class b stars.  I've found a lot 
of class b stars, just none that are the same size. 

Thanks,
Ryan
