The spotting of strontium has helped open the eyes of the astronomers regarding the presence of certain elements in the Universe. Strontium has been found to be the result of a collision between two neutron stars. In the kilonova, it is for the first time that the scientists found the presence of an unknown heavy element. The new element can help uncover a number of facts surrounding the source of heavy elements form. The Interferometer Gravitational-Wave Observatory (LIGO) and the European VIRGO observatory had identified gravitational waves emerging from the fusion of two neutron stars. This event was termed GW170817 and it was found to have happened in the galaxy NGC 4993 around 130 million light-years away.
The new kilonova has been named AT2017gfo and the European Southern Observatory (ESO) has used many of its telescopes to observe it in a range of wavelengths. The X-shooter instrument of the Very Large Telescope (VLT) was able to get a clear idea about the kilonova. The multi-wavelength spectrograph used Ultraviolet B, visible light, and near-infrared light to observe the event. Previously no individual elements could be identified, but now the new results show presence of strontium in the merger of two neutron stars. According to Darach Watson from the University of Copenhagen, the comparison of the 2017 and present data has shown the collision of neutron stars to be the reason behind the presence of heavy elements in the Universe. The neutrons are made up of neutrons would not be proved spectroscopic study but the current discovery can as strontium is formed under extreme neutron flux.
Similarly, researchers recently found the largest neutron star that is almost 2.17 times the mass of the Sun. The Green Bank Telescope helped the researchers spot the star and it has been dubbed J0740+6620. This star has been found to have two unique phenomena: one, it is a pulsar and second, it is a binary system. Thus, the radio wave emission and its companion white dwarf have been found to have helped identify the small city-sized neutron star.
