Scientists believe that the mysterious signal that comes from our galaxy can be one of the rarest objects.
The paper, uploaded to the Arxiv server Praprint, discussed GLEAM-X J16279.5-523504.3 as a white pulsar dwarf.
Milky Way began to form relatively immediately after a large explosion of Bang marked the beginning of the universe around 13.8 billion years ago.
The sun, located approximately 26,000 light years from the supermassive black hole in the middle of the galaxy, is formed about 4.5 billion years ago.
According to a paper by Astrophysics Jonathan Katz University of Washington in St. Louis, “Since the beginning of the Pulsar astronomy days there is speculation that rotating magnetic dwarf may show activity such as pulsars.”
“The new transient periodic radio found GLEAM-X J162759.5-523504.3 is a candidate for the first true white dwarf pulsar. It has a period of 18.18 minutes (1091 s) and the pulse shows low frequency emissions (72-215 MHz) with The brightness of ~ 1016 K which implies coherent emissions. Does not have a binary companion that must be moved. Thus meets the classical Pulsar criteria, even though the period is hundreds of times longer than them. “
Low frequency radio source GLEAM-X J162759.5-523504.3 emits polarized emissions coherent pulses like that from pulsar radio.
But the period of 18.18 minutes is hundreds of times longer than a confirmed pulsar radio, and if it is a neutron star that the average radiation power exceeds the upper limit on its spin-down power with more than the size.
This can be explained if it is a white dwarf pulsar, with the moment of inertia some of the big sequences are greater than neutron stars. The Lorentz factor of emission load bunches can be limited from the bottom with the width of the temporal substructure of their radiation.
If emissions are radiation curvature, the fingers of curvature can be estimated from the Lorentz factor and emission frequency; This is consistent with magnetosphere inner white Dwarf but not neutron stars.
“Nobody hopes to detect it directly like this because we don’t expect them to be too smart,” Astrophysican Natasha Hurley-Walker from the node of the University of Curtin from the International Center for Radio Astronomy Research (ICRAR) in Australia explained at that time.
“Somehow it converts magnetic energy to radio waves is far more effective than anything we’ve seen before.”
“If it’s quite bright, optical observations can also determine the magnetic field, spectroscopically or polarm,” Katz explained.
“White dwarf that rotates fast, very magnetically, will promise the target for low frequency radio observations to determine whether they are white pulsars.”
