| Abstract: |
Two greatest enigmas of modern science: dark matter and dark energy, stimulate theoretical physicists to go beyond the standard physics
and develop non-standard ideas, such as: an assumption that our world might have more than four dimensions, the existence of new particles
(supersymmetric particles, axions, etc.) or speculations that fundamental constants of nature might vary in time.
This contribution reviews the constraints on such exotic physical ideas obtained from the pulsating white dwarf G117-B15A,
in which the cooling rate measured with asteroseismological techniques agrees very well with stellar evolutionary expectations, thus making this object
an excellent laboratory for astroparticle physics. |
