White dwarf stars in modified gravity
Aneta Wojnar
A few questions related to white dwarfs' physics is posed. It seems that the modified gravity framework can be a good starting point to provide alternative explanations to cooling…
Lithium abundance is a gravitational model dependent quantity
Aneta Wojnar
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…
Early evolutionary tracks of low-mass stellar objects in modified gravity
Aneta Wojnar
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 tempe…
Stability of polytropic stars in Palatini gravity
Aneta Wojnar
We will briefly discuss the necessary conditions for stability of polytropies in Palatini gravity and the differences with the General Relativity ones.
