Spectral Synthesis for Classical Ae Stars: Hα and Ca II
Classical Ae (CAe) stars are main-sequence, A-type stars with Hα emission but no signature of dust; they are thought to be the cool extension of classical Be (CBe) stars to lower stellar masses. We investigate the use of Hα and the Ca ii IR triplet observed at low spectroscopic resolution ( R=1800 ) as diagnostics for...
