did u know that the names Regulus, Sirius & Bellatrix are really stars' names???
For example, Sirius (alpha canis Maioris) u'll find it in Canis Maior constellation and this star is the brightest one in all the sky. Then, Regulus is in Leo's constellation & Bellatrix is in Orion. Try to get a sky map and find those stars, u'll see that the stars are so beautiful like HP's characters mentioned. do u think that JK got inspired in the stars to named the characters??? this would be a nice pick...
