R136a was resolved using speckle interferometry and eventually space-based observations into as many as 24 components, dominated by R136a1, R136a2, and R136a3, all three being extremely massive WNh stars several million times more luminous than the sun.
R136a was resolved using speckle interferometry to identify a system of 24 components, with R136a1, R136a2, and R136a3 being the most prominent members, all three being massive WNh stars many times brighter than our sun.
