| This project aims to search for imprints of new forces using stars as laboratories. The end point will be to make predictions for the impact of new physics on the structure and pulsations of stars and confront with observations. The choices of stars to be employed is broad, ranging from the Sun to white dwarfs and red giants.
The student will familiarise with the concepts of state-of-the-art theories of dark energy or extensions of the standard model of particles (e.g axions, dark matter theories), as well as with the physics of stellar evolution and asteroseismology. The project has a theoretical and numerical component. On the theoretical part, the student will model the impact of new physics on stellar observables and test against observations. The numerical part will use state-of-the-art simulation codes for stellar evolution/asteroseismology to deliver accurate solutions of the equations. |

| Our current understanding of the standard paradigm of particles and forces in the Universe is strongly challenged by key observations. Probably, the most puzzling one is the mysterious “dark energy” problem which calls for new forces beyond the standard model of particles and General Relativity. New particles are expected to leave their imprints at different scales in the Universe: from cosmological scales to gravitational waves and stellar interiors.
