Magnetic fields can significantly influence oscillations in the fusion of neutron stars, the study finds

Magnetic fields can significantly complicate how scientists interpret signals from gravitational waves of neutron star mergers, a new study has revealed. These collisions, where two super dense stellar remnants merge, have long offered astrophysicists a way to investigate matter under extreme pressure. The results of the University of Urban-Champaign and the University of Valencia reveal that robust magnetic fields form more complex and long standards in gravitational wavesmaking it more difficult to decipher the internal operation of Neutron stars. The results could condemn the strategies of interpretation of the postfusion signal and the equation of dense matter states, while scientists prepare to observe the next generation of gravitational wave observatories.

Magnetic fields considered to distort signs of frequency in neutron star mergers

According to the to study Published in physical review letters, the researchers simulated Magneto Magnetic fields affect the frequency signs of the remnants left behind after a fusion. They represented real world conditions by applying two different state equations (EOS) to neutron stars, different magnetic field settings and various mass combinations.

According to the leader Researcher Antonios TsokarosThe magnetic field can cause frequency changes that can misunderstand scientists to incorrectly attribute them as indications of other physical phenomena, such as phase transitions or Quark-Hardon crossover.

Discoveries also imply that scientists need to be cautious about how they interpret signs of neutron star mergers, so they do not turn into as they form. They found that strong magnetic fields can alter the typical frequency of oscillation of the issued signals, changing them of what they should be and what was foreseen by one or the other of the competing equations of state in play within these fierce events.

They also found that, in the most direct type of galaxies mergers they considered in their simulations, the magnetic field became excessively amplified, so that a larger proportion of fusion remnants is more likely to produce additional gravitational wave emissions.

Magnetic fields maintain the key to unlocking neutron star fusions secrets

Neutron stars are the left of massive stars that collapsed and contain such a dense story that a complete teaspoon would weigh billions of tons. They have Thermodynamic properties which are determined by EOS and magnetic fields, some orders of magnitude stronger than those that can be produced in a human laboratory.

These extreme characteristics also make neutron stars useful to investigate the laws of physics under intense pressure and magnetism. Since it was detected on gravitational waves and rays Gama in 2017, the scientific community has been busy about research on neutron star mergers, leading to an increasing number of studies related to these types of mergers.

Professor Milton Ruiz also warns that it would be a mistake to misunderstand the observations in the future without considering the effects of magnetic fields. High resolution simulations are needed, researchers said to refine our understanding of how magnetic fields shape cosmic events and strive like Einstein’s telescope and the cosmic explorer on the horizon.
