Abstract

Bu çalışmada açık kaynak kodlu Einstein Toolkit ve Lorene paket programları kullanılarak parçalı politropik hal
denklemi ile tanımlanmış eş kütleli nötron yıldız çiftlerinin simülasyonları aracılığıyla sistemin başlangıç toplam kütlesinin etkisi araştırılmıştır. Sistemlerin toplam baryonik kütleleleri 3.2, 3.4, 3.6 ve 3.8 M⊙olarak ele alınmıştır. Birleşmenin öncesi ve sonrasını içeren gravitasyonel dalga formu elde edilmiş ve sistemlerin gravitasyonel dalga dedektörleri ile gözlenip gözlenemeyeceği tartışılmıştır. Yapılan simülasyonlar sonucunda tüm modellerimizin birleşme sonrasında 1 ms’den daha kısa bir süre içerisinde kara deliğe çöktüğü görülmüştür. Son olarak, sistemlere ilişkin simülasyonlar sonucunda elde edilen parametreler tartışılmıştır.

General Relativistic Simulations of Binary Neutron Star Mergers: Prompt Black Hole Formation

Year 2023, Volume: 4 Issue: 3 - Special Issue: Proceedings of the 22nd National Astronomy Congress, 34 - 38, 31.12.2023

Abstract

In this study, we investigate the impacts of the initial mass of the system on the equal mass binary neutron star defined
piecewise polytropic EOS by using open source codes Einstein Toolkit and Lorene. We restrict ourselves to systems
with total baryonic mass 3.2, 3.4, 3.6 and 3.8 M⊙. We extract gravitational waveform, which contains an inspiral and
post-merger stage and discuss if gravitational wave detectors may observe our models. The results show all of our models collapse promptly into a BH before 1 ms. Finally, the parameters obtained as a result of the simulations are discussed.
