Signal Discovered in Space Could Be a Star’s Heartbeat

There is a whole universe outside of Earth and many things waiting to be discovered. Astronomers are making intriguing discoveries about space every day. In some of these researches, planets, interesting images and objects that are thought to have similar life conditions to Earth are encountered.

A new one has been added to these discoveries that astonished astronomers and us. The radio signal discovered in the Milky Way, which includes Earth, is thought to be a very rare object.

For the first time, a white dwarf is thought to be moving like pulsars

According to the article shared by astrophysicist Jonathan Katz of the University of Washington, GLEAM-X J162759.5−523504.3 The radio signal, called The object is thought to be a white dwarf pulsar; which is rare for white dwarf dwarfs that cannot be proven to exhibit pulsar-like activity. pulsars like a heartbeat white dwarfs exhibit rhythmic movements. extinct and at the end of his life are stars. For this reason, it was considered very unlikely that these older stars would exhibit movements like pulsars.

If this periodic radio signal is discovered; managed to excite astronomers with the possibility that it may belong to the first true white dwarf pulsar. of the radio signal periods, frequency height and brightness. Astronomers who studied it discovered that the signal had characteristics of pulsars. 18.18 minute period It is thought that this low-frequency radio signal, which has a low frequency, may have been detected before. The researchers say that the astronomers who encountered this signal before could not identify the object that could emit the frequencies, so they could not reach a conclusion.

These radio signals are thought to have been first encountered in 2018.

First, these signals in Australia in 2018 thought to have been found. It was noticed that the data collected by the Murchison Widefield Array had similar properties to pulsars. However, at that time, these data were not matched to the profile of any astronomical object and it was thought to be an ultra-long-period magnetar. However, astronomers could not come to a clear decision about the object, considering that the probability was very low and that this discovery could belong to something else. With this discovery today have the same period These signals are thought to be objects that could not be determined and that caused controversy at that time.

After the discovery of the radio signal, astrophysicist Jonathan Katz thought it could not be caused by a pulsar. The reason why he thinks this is; It has a long rotation period and the pulses it causes are too bright for a neutron star pulsar. Katz argues that these problems are just the object of their discovery. a white dwarf pulsar discovered that if it does, it will be resolved. If Katz’s thesis is true, then radio first white dwarf to have the mechanism of pulsars may have been discovered. If this information that astronomers have is proven, other white dwarfs with similar characteristics will be discovered much more easily.
