  • A large body of evidence points to the existence of an extended, complex coronal magnetosphere originating at the cooler K subgiant

  • Here we report multi-epoch radio imaging of the Algol system, in which we see a large, persistent coronal loop approximately one subgiant diameter in height, whose base is straddling the subgiant and whose apex is oriented towards the B8 star.

  • The paradox is a result of Algol A being more massive star of the binary pair, yet still a main sequence star, while the less massive Algol B has already reached the subgiant stage in its evolution.

  • The close binary Algol system contains a radio-bright KIV subgiant star in a very close (0.062 astronomical units) and rapid (2.86 day) orbit with a main sequence B8 star.
