WR 102's size compared to the sun. WR 102 is a Wolf–Rayet star in the constellation Sagittarius , an extremely rare star on the WO oxygen sequence. It is a luminous and very hot star, highly evolved and close to exploding as a supernova.
WR 102c is surrounded by a shell of nebulosity which contains dust made even hotter than the star itself by intense radiation. The nebula also includes nearly 1 M ☉ of molecular hydrogen and around 10 M ☉ of ionised hydrogen, all expelled from the star. [4] There is a suggestion that WR 102c may be a binary star.
WR 102ea is a Wolf–Rayet star in the Sagittarius constellation. It is the third most luminous star in the Quintuplet cluster after WR 102hb . With a luminosity of 2,500,000 times solar , it is also one of the most luminous stars known.
WR 136, a WN6 star where the atmosphere shed during the red supergiant phase has been shocked by the hot, fast WR winds to form a visible bubble nebula. In 1867, using the 40 cm Foucault telescope at the Paris Observatory, astronomers Charles Wolf and Georges Rayet [1] discovered three stars in the constellation Cygnus (HD 191765, HD 192103 and HD 192641, now designated as WR 134, WR 135, and ...

Arches-F1 (WR ...
Narrowband infrared observations of several spectral features around 2 μm showed that WR 102ka was a Wolf Rayet star with a likely classification of WN10. [7] It was also proposed as a possible luminous blue variable. [8] The Spitzer Space Telescope observed WR 102ka at wavelengths of 3.6 μm, 8 μm, and 24 μm on April 20, 2005. These ...
“Like I told him earlier, he has to learn how to control that speed because somebody that fast can find themselves being out of control.”
astro: luminosity per square meter of the hottest normal star known, WR 102: 5–20 × 10 13: weather: rate of heat energy release by a hurricane [citation needed] 10 14: 1.4 × 10 14: eco: global net primary production (= biomass production) via photosynthesis [47] 2.9 × 10 14
