Online Seminar〝Stellar and substellar objects in modified gravity- matter properties and tests of gravitational models〞

Star-UBB Seminar Series:- Stellar and substellar objects in modified gravity- matter properties and tests of gravitational models

The speaker will provide a brief overview of the latest research in the physics of (sub-)stellar objects in the context of modified gravity. Our primary focus will be on the matter’s properties of these objects, including the equation of state, specific heats, and other relevant characteristics. Additionally, she and audiences will explore the internal processes of these objects, such as light element burning, crystallization, and cooling, and discuss potential methods for testing modified gravity theories using seismic data.

Scientific and Technological Advanced Research- Babeș-Bolyai University(Star-UBB) Seminar Series in Gravitation, Cosmology and Astrophysics

Presently a period of rapid and intense change are being witnessed in our understanding of the gravitational force, at a rate that is quickly increasing since the important observational discoveries of the late 1990s. With the advent of new observational techniques, the emergence of important cosmological and astrophysical paradigms can be seen that lead to a deep change in our understanding of the Universe. Astronomical observations strongly suggest that at large scales the force of gravity may not behave according to standard general relativity, and that a generalization of the gravitational action, either at the geometric level, or at the matter level, may be required for a full understanding of the gravitational interaction.

The goal of the present seminar is to bring Theoretical Gravitational Physics closer to the observations and experiments, and to discuss current topics in general relativity, high-energy physics, astrophysics and cosmology.
