Something Deep in Our Galaxy Is Pulsing Every 44 Minutes. No One Knows Why.

This mysterious object could take many forms, including a pulsar, a white dwarf star in a binary with a low-mass star, or a magnetar. The radio wave intensity of ASKAP J1832-0911 cycled every 44 minutes, and was exceptionally bright in radio at the time of observation. Well, it might be a binary white dwarf system—fast-spinning white dwarfs are sometimes found locked in binary systems with other low-mass stars. The radio emissions from these binaries are usually significantly weaker than those from ASKAP J1832–0911, but Wang suggests that the situation remains possible. Older magentars are thought to act more like this, but cannot reach such bright radio extremes as ASKAP J1832–0911.
