Constraining the time variation of Newton's constant $G$ with gravitational-wave standard sirens and supernovae

Wen Zhao, Bill S. Wright, Baojiu Li

The intrinsic peak luminosity of Type Ia supernovae (SNIa) depends on the value of Newton's gravitational constant $G$, through the Chandrasekhar mass $M_{\mathrm{Ch}}\propto G^{-3/2}$.…
