The excess infrared emission is the signature of warm material around the central objects rather than light coming from their atmospheres alone.

The researchers estimate masses near two and ten Jupiters for the pair. That makes the fainter LRL 2296 the least massive known brown dwarf with evidence of a circumstellar disk.
