Abstract

When stars are gravitationally bound in a binary or higher order multiple system there is a chance they can interact, enabling mass and momentum transfer. Such interactions can be life-changing events for the stars involved as they can change their internal mixing, final mass and rotational speeds. In these proceedings, we describe our recent work which provides evidence that an interaction in a previous triple system caused a merger, the product of which is a magnetic star. This created the system as it is seen today - a massive binary system surrounded by an enriched ejecta nebula where only one of the massive stars is magnetic.
