Physics of the stars
WebbOne way to come to grips with the physics of stars is to look at the timescales on which they change, or on which important internal processes come to equilibrium. Dynamical timescale Suppose the internal pressure of the sun were suddenly removed. The outer radius, R, would collapse under gravity according to d2R dt2 = − GM⊙ R2(t) R(0) = R ... Webb11 apr. 2024 · Massive stars die with a bang, exploding in a blaze of light, leaving behind a neutron star—an object that is among the densest in the Universe. Cosmically, these “core-collapse supernovae” (CCSNe) events are not rare. But in our Galaxy, they occur only once every 100 years.

The closest star we have around us is the sun. It is the only star in the solar system and the one that provides us with light and heat, making life possible on our planet.

A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.
