The pulsating red supergiant Antares (“anti-Mars”), at V = 1.06, is the 15th-brightest star in the night sky, but it gets less attention than its near-twin Betelgeuse. Check the length of their entries in wikipedia, for instance.
El estadio Be no es sólo una etapa evolutiva en las vidas de algunas estrellas calientes de tipo B de rápida rotación sino también un fenómeno transitorio que puede ir y venir con el paso de los años en la misma estrella. Varias razones se han propuesto para explicar el comportamiento de estas estrellas y aun están en debate.
Be-ness is not only an evolutionary stage in the lives of some rapidly rotating hot B-type stars but also a transient phenomenon that may come and go over the years for the same star. Several reasons have been proposed to explain the behavior of these stars and are still in debate.
