A dense $mathbf{0.1 M_{rm odot}}$ star in a 51-minute orbital period eclipsing binary

Kavli Affiliate: Saul Rappaport | First 5 Authors: Kevin B. Burdge, Kareem El-Badry, Thomas R. Marsh, Saul Rappaport, Warren R. Brown | Summary: In over a thousand known cataclysmic variables (CVs), where a white dwarf is accreting from a hydrogen-rich star, only a dozen have orbital periods below 75 minutes. One way to achieve these […]
