   combined, two stars at the same temperature can be vastly different in brightness because of their sizes. Image: Betelgeuse (Hubble Space Telescope.) It is 950 times bigger than the sun! The basic formula that relates stellar light output (called luminosity) with the surface area of a star, and the temperature of the star, is L = A x F where the

   Pollux is ≈ 8 times larger than the sun. NB: Thanks to the Stefan-Boltzmann law, astronomers can calculate the radii of the stars. The brightness of a star is: L = 4πσR2T4 L is the brightness, σ is the Stefan-Boltzmann constant, R the radius of the star and T the temperature.

   Sep 16, 2020 · When a star that is eight times larger than the sun ends its life, it does not go gentle into that good night. Shifting pressure in its core causes it to collapse and trigger a supernova, the largest explosion in the universe. The initial flash of light, which can outshine the star’s host galaxy, may last only seconds.

   22. According to current knowledge, yes. If the gas cloud is too massive, the pressure of the radiation prevents the collapse and the star formation. The article Stars Have a Size Limit by Michael Schirber, it's about 150 Solar Masses. However, there's the Pistol Star, which is speculated to be 200 SM. In the article 'Das wechselhafte Leben der ...

   Why is a Star 950 times bigger than the Sun?

   • The hotter a surface is, the more light it produces. The bigger a star is, the more surface it has. When these relationships are combined, two stars at the same temperature can be vastly different in brightness because of their sizes. Image: Betelgeuse (Hubble Space Telescope.) It is 950 times bigger than the sun!

   How much mass does a star have?

   • His computations found a wide range of upper mass limits - 10 solar masses for pure helium stars, and 200 solar masses for pure hydrogen stars. Most stars fall in the middle, and so will have different limits. The actual formation of massive stars also puts constraints on the mass.

   What is the size difference between a planet and a star?

   • Our Universe is really vast and empty, though a few grains of matter dotting the cosmic void, from small dust grains to the biggest stars. Between small planets in the solar system and the biggest stars, the size difference is enormous, for example, the diameter of the star Betelgeuse is 141,863 times larger than the diameter of the Earth.

   Can a star form if mass is over 100 SM?

   • However, there's the Pistol Star, which is speculated to be 200 SM. In the article 'Das wechselhafte Leben der Sterne' by Ralf Launhard (Spektrum 8/2013) there's a diagram with information that when the mass is over 100 SM, the star can't form because of radiation pressure. The exact value of the limit is not speculated in the article.

   What happens if a star flies into space?

   • Shifting pressure in its core causes it to collapse and trigger a supernova, the largest explosion in the universe. The initial flash of light, which can outshine the star’s host galaxy, may last only seconds. But the resulting debris that is flung into space can be studied for millennia.

   Jul 4, 2024 · After the main sequence, a high-mass star finishes its life cycle in the following evolutionary stages: Red supergiant → supernova → neutron star (or black hole) The key differences between a lower mass and higher mass star at this stage are: A higher mass star will stay on the main sequence for a shorter time before it becomes a red ...
