Stars as physics laboratories: from dark matter to modified gravity
Instituto Superior Técnico
The present accuracy in the modelling and observations of the Sun and other stars allows us to use them as laboratories of physics. In this talk I will discuss how the capture of dark matter particles by low-mass stars may impact the properties of individual stars and the global characteristics of stellar clusters. I will present recent constraints on the dark matter parameter space from an asteroseismic analysis of Alpha Cen B. To conclude, I will show how a similar approach was successfully applied to test alternative theories of gravity, using solar neutrinos and helioseismic data.
