More recently, Houk (1982) listed a class of F3 V, matching an ordinary main-sequence star that is generating energy through hydrogen fusion at its core. The NStars project gives it a classification of F2 V.
In recent studies, Houk (1982) noted a class of F3 V stars, which are main-sequence stars generating energy via hydrogen fusion in their centers. The NStars project has assigned these stars the classification of F2 V.
