Neutron Star Meeting

Neutron stars are the end products of moderately massive stars and have extremely high density, very strong magnetic fields, and very fast rotations about their own axis. Neutron stars are the best natural laboratories to test aspects of extreme physics that include states of matter at extremely high density, strong gravitational fields, detection of low frequency gravitational waves, etc. These are possible when pulsed electromagnetic emissions from the neutron stars can be observed, i.e., neutron stars behave as pulsars. In this meeting, we will discuss recent trends and open challenges in using observational data of neutron stars to probe extreme physics.

In-person participation by invitation only. Please write to the Scientific Organising Committee if you are a PhD student/postdoc/faculty working in the field of neutron star and interested in attending in person.
