Pulsations induced by deuterium-burning in young brown dwarfs (2005)
Palla, Francesco, Baraffe, Isabelle
Very low-mass stars and brown dwarfs can undergo pulsational instability excited by central deuterium burning during the initial phases of their evolution. We present the results of evolutionary and...
