ASKAP J1832-0911 is a stellar object referred to as an extremely bright "long period radio transient" (LPT). Its unusual properties are unlike those of any other known object. It is has been hypothesized to be either an old magnetar or an ultra magnetized white dwarf, [1] [2] although discoverer Ziteng Wang says that "those theories do not fully explain what we are observing." [3]
ASKAP J1832 was identified through observations taken at the Australian Square Kilometre Array Pathfinder, and was serendipitously discovered in the X-ray band when a coincident observation conducted through the Chandra X-ray Observatory targeting the supernova remnant SNR G22.7–0.2 was able to detect it. [4] [ failed verification ] [2]
A body referred to as a long-period transient (LPT), ASKAP J1832 is a body which emits radio pulses and x-ray radiation 2 minutes in duration every 44 minutes and is located within the Milky Way about 15,000 light-years away from Earth. [4] There exists uncertainty of the object's stellar identity, with some believing it may be a magnetar or a white dwarf. [4]
