Abstract
LIVE STREAMING
I will briefly present the recent works related to effects of modified gravity on stellar and substellar objects. We will discuss some of their evolutionary phases, internal processes as well as possible tests with the use of those objects.
Diagram of the gravitational parameter space reveals a noticeable untested regime for the curvature between 10^(-38) – 10^(-50), that is, galaxy and stellar physics regime. This gap separating small-scale systems such as compact objects and Solar System from the cosmological regime could potentially hide the onset of corrections to GR. Credits: T.
