WR 93b is a Wolf-Rayet star in the constellation Scorpius, an extremely rare star on the WO oxygen sequence. It appears near NGC 6357 in the tail of the scorpion. WR 93b was discovered in 2003 during a study of emission line stars from the AAO / …

2004年3月19日 · The optical spectrum of this star, to become WR 93b in the Catalogue of Galactic Wolf-Rayet stars, is presented and described. WR 93b is classified as WO3 and is shown to be highly reddened (E(B-V) = 2.1 pm 0.1). A recombination line analysis of the emission lines yields the abundance ratios C/He = 0.95 and O/He = 0.13 (by number).

Estimation of the wind terminal velocity in WR 93b at 5750 km s -1 makes this star the current wind-speed record holder among all non-degenerate stars. We report the discovery of only the fourth massive WO star to be found in the Milky Way, …

WR 93b is classified as WO3 and is shown to be highly reddened [E(B − V) = 2.1 ± 0.1]. A recombination-line analysis of the emission lines yields the abundance ratios

2004年3月19日 · Estimation of the wind terminal velocity in WR 93b at 5750 km s−1 makes this star the current wind-speed record holder among all non-degenerate stars.

2023年11月12日 · WR 93b is a Wolf-Rayet star in the constellation Scorpius, an extremely rare star on the WO oxygen sequence. WR 93b was discovered in 2003 during a study of emission line stars from the AAO/UKST Southern Galactic Plane Hα Survey. It was published as the fourth galactic WO class star in 1994.

2022年8月28日 · WR 93b is a Wolf-Rayet star located in the constellation Scorpius around 7,470 light years away. It is one of only four oxygen-rich Wolf-Rayet stars in the Milky Way, making it among the rarest stars in the universe. The surface temperature of WR 93b is around 287,540 degrees Fahrenheit (159,727 degrees Celsius). WR 93b is 110,000 times ...

WR stars in low-metallicity environments are expected to have higher stellar temperatures than those in the Galaxy. WO stars are often thought to represent the nal stage in the evolution of stars initially more massive than 25 M (Meynet & Maeder 2003), i.e. including very massive stars that may avoid a red supergiant phase. If this is the case,

The optical spectrum of this star, to become WR 93b in the Catalogue of Galactic Wolf–Rayet stars, is presented and described. WR 93b is classified as WO3 and is shown to be highly reddened [E(B−V) = 2.1 ± 0.1].
