Une équipe de chercheurs britanniques, allemands et sud-africains viennent de découvrir une seconde naine blanche pulsante en ondes radio et en rayons X, après avoir découvert la première du genre en 2016 (AR Sco). Cette seconde naine blanche "pulsar" est nommée J1912-4410. Ils publient deux articles, le premier dans Nature Astronomy, sur la découverte, et le second dans Astronomy&Astrophysics sur le rayonnement X de la naine blanche.
