Weak X-ray Bursts on Slowly Accreting Neutron Stars, Fall 2023-Spring 2025
Michigan State University
Paper: https://ui.adsabs.harvard.edu/abs/2025arXiv250615818C/abstract
Collaborators: Simon Guichandut, Andrew Cumming, and Edward F. Brown
Recent observations of weak X-ray bursts from SAX J1808.4−3658 occurring within 1–3 days of the outburst have renewed interest in the possibility of X-ray bursts triggered by thermally unstable hydrogen ignition, analogous to classical novae. Using the stellar evolution code MESA, we explore the unstable ignition of hydrogen. For accretion of solar composition, the bursts are too weak to be observed. However, for large enough metallicity enhancement, we achieve a peak luminosity consistent with the SAX J1808.4−3658 burst.

Utilizing the NASA HEASARC archive to extract light curves and spectra of neutron star SAX J1808.4−3658 to analyze weak X-ray bursts. Fitting spectra to create a model and understand the underlying physics of the burst. To our knowledge, this observation provides some of the first strong observational evidence of hydrogen-powered bursts.

Characterizing Galactic Binaries In the Cloud with LISA, Summer 2019
Intern at NASA Goddard Space Flight Center
Advisor: Ira Thorpe
A Markov Chain Monte Carlo (MCMC) method was utilized to account for the amount of simultaneous sources and implemented on a cloud computing facility. Using cloud computing sets up a platform that can be manipulated to fit the needs of many computing situations and is ideal for large data. This platform was created from the ground up and has been used to reproduce the results of previous codes to demonstrate the ability and effectiveness of cloud computing.
