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.}, organization = {- NSF (grant AST-1615456) - Mount Cuba Astronomical Foundation}, publisher = {American Astronomical Society}, title = {Orbital period increase in ES Ceti}, doi = {10.3847/1538-4357/aa9ed6}, author = {Miguel Agustino, Enrique de and Patterson, Joseph and Kemp, Jonathan and Myers, Gordon and Rea, Robert and Krajci, Thomas and Monard, Berto and Cook, Lewis M.}, }
