Abstract: Accretion (traced by X-rays) and jets (traced by radio emission) are ubiquitous and connected processes in compact objects. Accreting neutron stars – where the compact object is accreting material from a stellar companion are the ideal systems to study this coupling relationship due to their varying observed states (i.e. accretion rate, stellar companion type, etc.). However, the qualitative link between accretion and jets is much less understood for neutron stars. Their distances are generally unknown or poorly constrained and neutron stars tend to be radio quieter, therefore limiting the ability to draw accurate conclusions about the physics of neutron star’s accretion. Despite the challenge, radio continuum studies of neutron stars are needed to understand their broad range of physical properties that are likely to affect their jets/outflows. In this talk, I will summarize my research across a wide range of accreting neutron star types using radio observations from NRAO’s Karl G. Jansky Very Large Array and the Australia Telescope Compact Array. In particular, I will present recent results of our surveys and conclude with a brief discussion of the implications our results have for future radio facilities such as the Next-generation Very Large Array and the Square Kilometre Array.
