Research Topic: Study of the Key Resonance for Thermonuclear Runaways on Neutron Stars Graduation Year: 2024

Undergraduate Research in the Neighborhoods

The goal of Ari’s project was to focus on understanding the properties of neutron stars through the observation of X-ray bursts. When a hydrogen-rich star interacts with a neutron star, it undergoes mass accretion, leading to hydrogen fusion into helium, resulting in X-ray bursts observed by space telescopes. The light curves of these bursts help identify the neutron star’s properties, such as mass, temperature, and magnetic field. Ari’s research objective was to measure the uncertainty 15O(a,y)19Ne reaction rate, that is crucial for understanding the crust evolution of neutron stars. The experiment involved using the GADGET II system, which includes a Gaseous detector with germanium tagging (Gadget) and the Decay Germanium Array initiator (DeGai), to detect delta gamma rays after beta decay. Ari created simulations of the experiment to justify the hypothesis before the experiment was performed.
