Physics-Based Modeling of Multi-Wavelength Emission from Millisecond Pulsars
Speaker: Siddhant Solanki, UMD Astronomy
Abstract: The mass-radius measurements of neutron stars provide important constraints on the equation of state of ultra-dense matter. The masses and radii of some millisecond pulsars (MSPs) have been estimated by modeling their surface thermal X-ray emission using the NICER data. In this talk, I will discuss several improvements to this analysis that use advances in magnetospheric theory and constraints from multi-wavelength observations. I apply this framework to PSR J0740+6620 and show how the updated analysis offers information about the plasma discharge cycles, in addition to the mass and radius estimates.
