Cooling of Compact stars
 Schematic
introduction of simulations
 Configurations
of Compact stars
 Cooling processes
 Crust, SC Gaps and ...
 Time Evolution of Surface Temperature
 Constraints from Observations
 Summary & Discussion
Quasi-Equilibrate Evolution of
Compact Objects


How to distinguish the different
types of Hybrid star models from
cooling evolution?
Statistics of Compact stars
Could the Mass
Distribution of
NSs be
exstracted from
the cooling
models?
 Cooling
of NSs is one of testing schemes for
High density matter EoS
 Mass distribution of NS is extracted from the
cooling model
 Cooling data allowed existence of HS even
with one flaver QM
 DU can be consided as a problem
 Do
Hybrid NSs an alternative or the solution of
problems of compact stars?
 Do for all constraints exist a valid HNS model?
 Can magnetic field and surface heating
modify the main conclusions on cooling of NS?
 Is the mass distribution of NSs an obsorvable?
