The binary period icreases rapidly, with with P/P = 6.2 x 106 years. This is consistent with the assumption that gravitational radiation (GR) drives the mass transfer, and it appears to be the first dynamical evidence that GR is indeed the driver of evolution in this class of very old cataclysmic variables -the AM Canum Venaticorum stars.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Accretion, accretion disksBinaries: closeNovae, cataclysmic variablesStars: individual (ES Ceti)journal article10.3847/1538-4357/aa9ed6open access21 Astronomía y Astrofísica
