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-typesupergiant. However, subsequent analyses have shown it to be not O but B-type,[5] as well as being possibly an LBV.[4]
Properties
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.
