Supergigantes

Las supergigantes son las estrellas más masivas y luminosas del universo. Si el Sol fuera un guisante, una supergigante roja ocuparía el espacio hasta la órbita de Júpiter. Las azules (clases O, B) son extremadamente calientes y jóvenes, consumiendo su combustible con rapidez. Las amarillas (clases F, G) son una fase de transición breve. Las rojas (clase M) son más frías, pero emiten mucha energía debido a su tamaño colosal. Existe una relación directa: a mayor masa, mayor es la temperatura y presión nuclear, lo que resulta en un brillo inmenso y un final explosivo como supernova.

Image: Observations reveal evidence of a potential stellar companion for the red supergiant Betelgeuse

Betelgeuse, one of the most prominent red supergiant stars in the night sky, has long been a subject of intense scientific inquiry. Recent analysis has sought to verify the existence of a secondary star orbiting this massive primary. By examining the star’s long secondary period of variability, which suggested the presence of an orbiting body, researchers targeted the system to confirm if a companion star was indeed present in the vicinity of this stellar giant. Using extreme adaptive optic...
