V1936 Aquilae is a blue supergiant and candidate Luminous blue variable located in the nebula Westerhout 51, in the constellation Aquila, about 20,000 light years away. The star was originally identified as a massive star in 2000, [3] and was thought to be an O-type supergiant. However, subsequent analyses have shown it to be not O but B-type, [5] as well as being possibly an LBV. [4]
V1936 Aquilae is a very luminous star. Recent measurements hint at a bolometric luminosity of around 560,000 L☉, assuming a distance of 6 kiloparsecs, consistent with the distance of Westerhout 51, the very large H II region (nebula) it is located in. The star likely has a temperature of around 13,200 K. [5] The Stefan-Boltzmann Law suggests a radius of around 143 times that of the Sun.
