A Strange Radio Pulse Began Looking Like a Binary
Two years of polarization and pulse evolution fit an ultra-compact asynchronous white-dwarf system.
Summary
Two years of polarization and pulse evolution fit an ultra-compact asynchronous white-dwarf system.
ASKAP/DART J1832-0911’s pulse shape, Faraday rotation, polarization and spectrum evolved in ways the authors say are atypical of pulsars and magnetars. An ultra-compact asynchronous polar explains much of the behavior and periodic X-rays, but the team cannot yet prove the binary interpretation and offers testable predictions.
Why it matters
Two years of polarization and pulse evolution fit an ultra-compact asynchronous white-dwarf system.
Limits and context
- An ultra-compact asynchronous polar explains much of the behavior and periodic X-rays, but the team cannot yet prove the binary interpretation and offers testable predictions.
