Hi guys It’s me, Antony…
So today we’re gonna discuss,
something very interesting…
The Wolf-Rayet Star
It seems Interesting Right.?
So, WR stars, or Wolf-Rayet stars, are a rare heterogeneous set of stars with unusual spectra showing prominent broad emission lines of ionized helium and highly ionized nitrogen or carbon.
The type was first distinguished in 1867 by the French astronomers Charles-Joseph-Étienne Wolf and Georges-Antoine-Pons Rayet.
A typical Wolf-Rayet star is several times the diameter of the Sun and thousands of times more luminous, The surface temperature of known Wolf–Rayet stars range from 20,000 K to around 210,000 K, hotter than almost all other kinds of stars.
Wolf-Rayet stars are rare, with less than 200 known in our galaxy. However, due to their intense brightness, these stars are clearly visible, with apparent magnitudes ranging from 9–12., located mostly in the spiral arms of the Milky Way Galaxy. Wolf-Rayets come in two flavors: WN (emission lines of helium and nitrogen) and WC (carbon, oxygen, and hydrogen).
The more massive a star is, the shorter its lifespan — and Wolf-Rayet stars are among the largest and shortest-lived stars known, typically over 20 solar masses
So that’s it, guys…
I’m ending this blog here,
hope it was a piece of new knowledge for at least some of you…
SeeYouSoon…
