Discovery

[W60] B90 was discovered in 1956 by Karl Gordon Henize in a catalogue of H-alpha emission stars and nebulae in the Large Magellanic Cloud.[5]

Properties

Luminosity and radius

[W60] B90 is believed to be one of the largest, most luminous stars in the Large Magellanic Cloud with a luminosity of more than 280,000 solar luminosities and a radius of around 1,390 solar radii.[2] It needs further investigation to constrain the luminosity and radius with higher certainty.[2]
