href="/wiki/Tipus_espectral" title="Tipus espectral">classe</a> d'<a href="/wiki/Estrella" class="mw-redirect" title="Estrella">estrelles</a> que són més brillants que el que és normal en el cas de les estrelles nanes de la <a href="/wiki/Seq%C3%BC%C3%A8ncia_principal" title="Seqüència principal">seqüència principal</a> de la mateixa classe espectral, però no tan brillants com les <a href="/wiki/Estrella_gegant" title="Estrella gegant">estrelles gegants</a>. Es creu que aquestes estrelles estan cessant o han cessat ja de <a href="/wiki/Fusi%C3%B3_nuclear" title="Fusió nuclear">fusionar</a> el seu <a href="/wiki/Hidrogen" title="Hidrogen">hidrogen</a>. En estrelles d'aproximadament una <a href="/wiki/Massa_solar" title="Massa solar">massa solar</a>, això causa que el nucli es contregui, la qual cosa augmenta la temperatura en el centre de l'estrella per produir una fusió de l'hidrogen en una escorça envoltant el nucli. Això propicia que l'estrella esdevengui una vertadera gegant. Al principi de la fase subgegant (com en una estrella com <a href="/wiki/Proci%C3%B3" title="Proció">Proció A</a>), el diàmetre i l'esclat han augmentat, però l'estrella encara no s'ha refredat ni ha canviat de color. Més tard, les subgegants que estan a punt de convertir-se en <a href="/wiki/Estrella_gegant" title="Estrella gegant">gegants</a> tenen un diàmetre més gran i més baixa temperatura que les estrelles de massa similar de la seqüència principal. En conjunt, la lluminositat canvia poc durant la fase subgegant, un fet prominent en els <a href="/wiki/Diagrama_de_Hertzsprung-Russell" title="Diagrama de Hertzsprung-Russell">diagrames de
