An Employee of the Centre for Astrophysics and Cosmology at the University of Nova Gorica Co-authored the Discovery of an Unusual Neutron Star

An employee of the Centre for Astrophysics and Cosmology at the University of Nova Gorica, Dr. Tanja Petrushevska, together with astronomers from the California Technology Institute (Caltech), co-authored the discovery of an unusual supernova compressed double neutron star.

As reported in the article published by scientists in the Science Journal, the supernova star turned out to be weaker than other similar objects during an explosion and faded away faster as well. This indicates that the exploded star probably had an invisible satellite that “stole” its matter. The explosion of such an “ultra-naked” star was weaker and shorter, since, as it is supposed, it was followed by the emergence of a neutron star. Since the star-satellite is also a neutron star, researchers believe that they have first witnessed the formation of a supernova star, in which a system of two neutron stars originated, moving one around the other at a very short distance. Thus, during observations of the explosion with the iPTF 14gqr sign, the birth of a neutron star was first detected, next to which is another neutron star.

In addition to the spectroscopic analysis of the iPTF 14gqr explosion properties, Tanja Petrushevska, together with other researchers from the University of Nova Gorica, takes part in other equally ambitious projects, for example in preparing the Large Synoptic Survey Telescope (LSST). It is currently being constructed in Chile. During several nights of searching for new sources of radiation, it will be able to examine the entire sky with the help of an impressive 8.4-metre mirror.
