Early evolutionary tracks of low-mass stellar objects in modified gravity

TL;DR

This paper investigates how modified gravity theories influence the early evolution of low-mass stars, affecting their structural properties, evolutionary tracks, and the maximum mass for fully convective stars.

Contribution

It introduces a simple model demonstrating the impact of modified gravity on stellar evolution and suggests a revised upper mass limit for fully convective stars.

Findings

Modified gravity alters Hayashi tracks and radiative core development.

Effective temperature, mass, and luminosity are affected by modified gravity.

The upper mass limit for fully convective stars may differ from standard estimates.

Abstract

Using a simple model of low-mass stellar objects we have shown modified gravity impact on their early evolution, such as Hayashi tracks, radiative core development, effective temperature, masses, and luminosities. We have also suggested that the upper mass' limit of fully convective stars on the Main Sequence might be different than commonly adopted.
