18 Dec 2015 | | Abstract: | Scalar-tensor theories of gravity can lead to modifications of the
gravitational force inside astrophysical objects. We exhibit that compact stars
such as white dwarfs provide a unique set-up to test such deviations from
Newtonian gravitational physics inside the stars. We obtain stringent and
independent constraints on the parameter $Upsilon$ characterizing the
deviations from gravity using the mass-radius relation, the Chandrasekhar mass
limit and the maximal rotational frequency of white dwarfs. We find that white
dwarfs impose stronger constraints on $Upsilon$ than the red and brown dwarfs. | | Source: | arXiv, 1512.5946 | | Services: | Forum | Review | PDF | Favorites | |
