1. 1. Atomic Structure Calculations Using Configuration-Interaction And Many-Body Perturbation Theory For Spectral Modelling Of Neutron Star Mergers : Example Of Ce I - Iv

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Fredrik Plane; [2023]
   Keywords : Computational atomic physics; Atomic physics; Physics; Astronomy; Astrophysics; Neutron stars; Stars; Relativisitc atomic physics; Configuration-interaction; Perturbation theory; Many-body perturbation theory;

   Abstract : The binary neutron star merger of 2017 and its corresponding electromagnetic signature resembling that of a kilonova has been one of the most groundbreaking astrophysical occurrences in the last decade. Indications of r-process nucleosynthesis in this event presents new opportunities for learning about the astrophysical origin of heavy elements. READ MORE

3. 2. Estimating Properties of a Young Pulsar through X-ray Observations - An Investigation of Parameter Dependence

   University essay from KTH/Fysik

   Author : Lurin Ali; [2022]
   Keywords : Pulsar; Neutron star; Supernova;

   Abstract : Studying the properties of newborn neutron stars is a complicated matter since they cannot be directly observed. Neutron stars are born when some massive stars go supernova (SN), where the expelled material from the explosion goes on to shield the young neutron star from our view by absorbing its radiation.

4. 3. Constraining the Neutron Star Equation of State

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Klara Olofsson; [2022]
   Keywords : neutron star; equation of state; dense matter;

   Abstract : Neutron stars are stellar objects of extreme properties. The dense core enables usto study nuclear matter beyond saturation density. The exact composition of matterat such densities is not yet established, but the thermodynamic states of the matteris theoreticized by the Equation of State (EOS). READ MORE

5. 4. Escaping Compact Object Binaries from Globular Clusters

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Annie Csomor; [2022]
   Keywords : Compact object binaries; binary black holes; BH-NS binaries; escaping binaries; globular clusters; escaping compact object binaries from globular clusters; escaping compact binaries; Physics and Astronomy;

   Abstract : Since 2015, the LIGO-Virgo-KAGRA scientific collaboration (LVK) has detected gravitational waves from more than 90 merging compact object binaries using ground-based interferometric detectors. Compact objects orbiting in binary systems emit gravitational waves leading to a loss of energy. READ MORE

6. 5. On Fermi-like neutrino acceleration in core-collapsesupernovae and around black hole formation, andthe evolution of observable neutrino flux duringproto-neutron star collapse

   University essay from Stockholms universitet/Institutionen för astronomi

   Author : Samuel Gullin; [2021]
   Keywords : core collapse black hole neutrino acceleration supernova;

   Abstract : Failed supernovae are the implosive final fates of massive stars, where ablack hole is formed. During the collapse, the proto-neutron star emits a huge number of neutrinos, and when the black hole is finally formed, it engulfs theneutrino-emitting material and the signal is cut off. READ MORE
