This type of star system is believed to be a precursor to merging double neutron star systems like the one that the LIGO (the Laser Interferometer Gravitational-Wave Observatory in the United States)\/Virgo discovered in 2017. The LIGO\/Virgo observation was important, because it confirmed the gravitational waves associated with merging neutron stars.<\/p>\n<p>The work published by this team today in the journal <em>Nature<\/em>, indicates these specific kinds of double neutron star systems may be the key to understanding dead star collisions and the expansion of the universe.<\/p>\n<p>\u201cBack in 2017, scientists at LIGO\/Virgo first detected the merger of two neutron stars,\u201d says physicist Robert Ferdman, who led the team. \u201cThe event caused gravitational-wave ripples through the fabric of <a href=\"https:\/\/www.ucf.edu\/space\/\">space time<\/a>, as predicted by Albert Einstein over a century ago. It confirmed that the phenomenon of short gamma-ray bursts was due to the merger of two neutron stars.\u201d<\/p>\n<p>One of the unique aspects of the 2017 discovery and today\u2019s is that the double neutron systems observed are composed of stars that have very different masses. Current theories about the 2017 discovery are based on the masses of stars being equal or very close in size.<\/p>\n<p>\u201cThe double neutron star system we observed shows the most asymmetric masses amongst the known merging systems within the age of the universe,\u201d says Benetge Perera, a UCF scientist at Arecibo who co-authored the paper. \u201cBased on what we know from LIGO\/Virgo and our study, understanding and characterizing of the asymmetric mass double neutron star population is vital to gravitational wave astronomy.\u201d<\/p>\n<figure id=\"attachment_110793\" style=\"max-width: 300px;\" class=\"figure float-left\"><noscript><img decoding=\"async\" width=\"300\" height=\"200\" class=\"figure-img  img-fluid w-100 size-medium wp-image-110793\" src=\"https:\/\/www.ucf.edu\/news\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo-300x200.jpg\" alt srcset=\"https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo-300x200.jpg 300w, https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo-768x512.jpg 768w, https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo-600x400.jpg 600w, https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo-360x240.jpg 360w, https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo.jpg 1200w\" sizes=\"(max-width: 300px) 100vw, 300px\"><\/noscript><img decoding=\"async\" width=\"300\" height=\"200\" class=\"figure-img  img-fluid w-100 size-medium wp-image-110793 lazyload\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20300%20200%22%3E%3C%2Fsvg%3E\" alt srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20viewBox%3D%220%200%20300%20200%22%3E%3C%2Fsvg%3E 300w\" sizes=\"(max-width: 300px) 100vw, 300px\" data-srcset=\"https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo-300x200.jpg 300w, https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo-768x512.jpg 768w, https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo-600x400.jpg 600w, https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo-360x240.jpg 360w, https:\/\/www.ucf.edu\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo.jpg 1200w\" data-src=\"https:\/\/www.ucf.edu\/news\/wp-content\/blogs.dir\/20\/files\/2020\/07\/WEBbenArecibo-300x200.jpg\"><figcaption class=\"figure-caption\">Observatory Scientist Benetge Perera.<\/figcaption><\/figure>\n<p>Perera, whose research is focused on pulsars and gravitational waves, joined the NSF-funded Arecibo Observatory in June 2019. The facility, which is managed by the University of Central Florida through a cooperative agreement with the NSF, offers scientists around the world a unique look into space because of its specialized instruments and its location near the equator.<\/p>\n<h3>The Discovery<\/h3>\n<p>The team discovered an unusual pulsar \u2013 one of deep space\u2019s magnetized spinning neutron-star \u2018lighthouses\u2019 that emits highly focused radio waves from its magnetic poles.<\/p>\n<p>The newly discovered pulsar (known as PSR J1913+1102) is part of a binary system \u2013 which means that it is locked in a fiercely tight orbit with another neutron star.<\/p>\n<p>\u201cThe Arecibo Observatory has a long legacy of important pulsar discoveries,\u201d says NSF Program Officer, Ashley Zauderer.&nbsp; \u201cThis exciting result shows how incredibly relevant the facility\u2019s unique sensitivity remains for scientific investigations in the new era of multi-messenger astrophysics.\u201d<\/p>\n<p>Neutron stars are the dead stellar remnants of a supernova explosion. They are made up of the densest matter known \u2013 packing hundreds of thousands of times the Earth\u2019s mass into a sphere the size of a city like New York.<\/p>\n<p>In about half a billion years the two neutron stars will collide, releasing astonishing amounts of energy in the form of gravitational waves and light.<\/p>\n<p>That collision is what the LIGO\/Virgo team observed in 2017. The event was not surprising, but the enormous amount of matter ejected from the merger and its brightness was unexpected, Ferdman said.<\/p>\n<p>\u201cMost theories about this event assumed that neutron stars locked in binary systems are very similar in mass,\u201d Ferdman says. \u201cBut this newly discovered binary is unusual because the masses of its two neutron stars are quite different \u2013 with one far larger than the other. Our discovery changes these assumptions.\u201d<\/p>\n<p>This asymmetric system gives scientists confidence that double neutron star mergers will provide vital clues about unsolved mysteries in astrophysics \u2013 including a more accurate determination of the expansion rate of the universe, known as the Hubble constant.<\/p>\n<p>Other members on the discovery team are: P.C.C. Freire from the Max-Planck Institute f\u00a8ur Radioastronomie in Germany, F. Camilo from the South African Radio Astronomy Observatory, J.M. Cordes from Cornell University, F. Crawrod from Franklin and Marshall College, J.W. T. Hessels from the University of Amsterdam and the Netherlands Institute for Radio Astronomy, V. M. Kaspi and E. Parent from McGill University, N. Pol from West Virginia University, I. H. Stairs from University of British Columbia. And J. van Leeuwen from the Netherlands Institute for Radio Astronomy.<\/p>\n<p>Perera has multiple degrees including a doctorate in physics from West Virginia University.
