  • Study Findings: A Binary Model of Long-Period Radio Transients and White Dwarf Pulsars

    Nature Astronomy abstract of study findings: Long-period radio transients (LPTs) represent a recently uncovered class of Galactic radio sources exhibiting minutes to hours periodicities and highly polarized pulses of seconds to minutes duration. Their phenomenology does not fit exactly in any other class, although it might resemble that of radio magnetars or white dwarf (WD) pulsars. Two…
