Gravity Defied (from potato asteroids to magnetised neutron stars) I : The self-gravitating objects

TL;DR

This paper explores various self-gravitating systems where additional physical effects like magnetic fields, rotation, or quantum phenomena counteract gravity, preventing collapse and creating diverse astrophysical objects.

Contribution

It introduces a series of studies examining how different physical mechanisms can oppose gravity in self-gravitating objects, expanding understanding of their stability and diversity.

Findings

Magnetic fields can stabilize certain astrophysical objects.

Rotation influences the shape and stability of self-gravitating bodies.

Quantum effects may prevent gravitational collapse in extreme conditions.

Abstract

Gravitation, the universal attractive force, acts upon all matter (and radiation) relentlessly. Left to itself, gravity would pull everything together and the Universe would be nothing but a gigantic black hole. Nature throws almost every bit of physics - rotation, magnetic field, heat, quantum effects and so on, at gravity to escape such a fate. In this series of articles we shall explore systems where the eternal pull of gravity has been held off by one or another such means.
