The influence of stellar objects mass distribution on their gravitational fields

TL;DR

This paper investigates how the randomness in stellar objects' mass distribution affects their gravitational fields and angular momentum evolution, showing that mass randomness preserves non-Gaussian fields but influences angular momentum dependencies.

Contribution

It provides a theoretical analysis linking mass distribution randomness to gravitational field characteristics and angular momentum evolution, validated by observational and simulation data.

Findings

Mass randomness does not change the non-Gaussian nature of gravitational fields.

Mass distribution influences the dependence of galaxy and cluster angular momenta on their richness.

Theoretical predictions align well with observational and simulation results.

Abstract

We study the influence of the astronomical objects masses randomness on the distribution function of their gravitational fields. Based on purely theoretical arguments and comparison with extensive data, collected from observations and numerical simulations, we have shown that while mass randomness does not alter the non-Gaussian character of the gravitational fields distribution, it changes the dependencies of mean angular momenta of galaxies and clusters on their richness. The specific form of above dependence is determined by the interplay of mass distribution character and different assumptions about cluster morphology. We trace the influence of masses distribution on the time evolution of stellar objects angular momenta in CDM and $\Lambda$CDM models. Our theoretical predictions are in very good coincidence with the statistical results derived both from observational data and numerical simulations.
