Alpheratz, at the cool end of the B star range (B8 subgiant) , is still hot, with a temperature of about 13,000 Kelvin. At a distance of 97 light years, we calculate a total luminosity, including the star’s ultraviolet radiation, of about 200 times that of the Sun. Alpheratz stands out in a couple of ways.
Is Alpheratz a a fast spinning star?
Alpheratz A is 240 times brighter than our Sun and it is also 2.3 times hotter than our Sun, having surface average temperatures of around 13,800 K. This star is also a fast-spinning star having a rotational velocity of around 52 km / 32.3 mi per second, and it is also a young star with an estimated age of around 60 million years.
How many times bigger is the Sun than the Alpheratz star?
Alpheratz estimated radius has been calculated as being 3.37 times bigger than the Sun. The Sun’s radius is 695,800km, therefore the star’s radius is an estimated 2,345,885.60.km. If you need the diameter of the star, you just need to multiple the radius by 2.
What is the Alpheratz’s solar mass?
The Alpheratz’s solar mass is 3.80 times that of our star, the Sun. The Sun’s Mass is 1,989,100,000,000,000,000,000 billion kg. which to calculate using this website is too large. To give idea of size, the Sun is 99.86% the mass of the solar system.
