Web12 jul. 2015 · It is this that sets an upper limit of around 60,000-70,000 K to the surface temperature of the most massive stars, which are dominated by radiation pressure. In regions of higher density or higher gravity, radiation pressure is not such an issue and temperatures can be much higher.

The bigger and more massive a star is, the more quickly it uses up its fuel. Once the hydrogen fuel in any star's core is gone, the star essentially leaves the main sequence and evolves into a different "type". That happens with all stars. how do you pronounce the name jochebed

Astronomers have struggled to understand how the largest stars — up to 120 times as massive as the Sun — can form by sucking in nearby matter. The problem is that, once a star reaches about 20 solar masses, the outward force of its intense radiation exceeds the gravitational force that pulls in matter. WebRed supergiants (RSGs) are stars with a supergiant luminosity class (Yerkes class I) of spectral type K or M. They are the largest stars in the universe in terms of volume, although they are not the most massive or luminous. Betelgeuse and Antares A are the brightest and best known red supergiants (RSGs), indeed the only first magnitude red supergiant stars. phone number for clear internet
