| Impact of rotation-driven particle repopulation on the thermal evolution of pulsars |
| Speaker: | Rodrigo Picanco Negreiros (Johann Wolfgang Goethe University, Frankfurt) |
| Abstract: | Driven by the loss of energy, isolated rotating neutron stars (pulsars) are gradually slowing down to lower frequencies, which monotonically increases the tremendous compression of the matter inside of them. This increase in compression changes both the global properties of rotating neutron stars as well as their hadronic core compositions. Both effects may register themselves observationally in the thermal evolution of such stars, as demonstrated in this work. We also find that the rotation-driven direct Urca process can comfortably explain the temperatures observed for the neutron star in Cas A provided the mass of this neutron star is assumed to be around 1.5 -- 1.9 \msun. |
