Une étoile bleu-blanc de la séquence principale est une étoile de type spectral BV. B est le type spectral à proprement parler, qui lui donne son nom de "bleu-blanc", et V (lire « cinq » en chiffres romains) est sa classe de luminosité, signifiant que c'est une « étoile naine », à comprendre ici dans le sens d'étoile de la séquence principale. L'expression naine bleu-blanc est parfois quoique rarement utilisé.
