Substellar Companions: Brown Dwarfs and Runaway Stars in the Cluster
When you gaze upon the Trapezium Cluster, you’re not only looking at a cradle of massive stellar giants but also at a congregation of enigmatic, elusive inhabitants known as brown dwarfs and runaway stars. These fascinating substellar objects represent a critical component of the cluster’s dynamic life and celestial activities.
Brown dwarfs, often dubbed ‘failed stars’, are particularly intriguing because they occupy the celestial grey area between the largest planets and the smallest stars. With masses too slight to initiate the fusion of hydrogen into helium—the defining process of stellar life—they glow faintly with the heat of their own formation, offering a glimpse into the variety of forms that celestial objects can take.
In contrast, runaway stars are recognized by their high velocities, a characteristic that hints at violent past events within the cluster. Perhaps they’ve been gravitationally slingshotted out of orbit by interactions with other massive bodies, or they’ve witnessed the explosive death of a binary partner. These dramas of galactic dimension underscore the intense forces and interactions at play in star-forming regions.
Let’s take a closer look at the data gathered from these fascinating celestial bodies:
