Cataclysmic variable ASASSN–14dx contains a massive pulsating white dwarf, observations find

An international team of astronomers has performed optical photometric, polarimetric and spectroscopic observations of a cataclysmic variable system known as ASASSN–14dx. Results of the new observations, published April 9 on the arXiv preprint server, indicate that the system harbors a massive pulsating white dwarf.
