Lithium abundance is a gravitational model dependent quantity

TL;DR

This paper shows that lithium abundance in low-mass stars depends on the gravitational model used, affecting age estimates of stars and clusters that rely on lithium depletion.

Contribution

It demonstrates the dependence of lithium abundance on modified gravity theories in low-mass stars, highlighting a new source of uncertainty in stellar age determination.

Findings

Lithium abundance varies with gravitational models.

Modified gravity impacts light element depletion.

Uncertainty in age estimates of stars and clusters.

Abstract

The dependence of lithium abundance on modified gravity in low-mass stellar objects is demonstrated. This may introduce an additional uncertainty to age determination techniques of young stars and globular clusters if they rely on the light element depletion method.
