  22. Thermo. exptrapolation by an additional term

  23. Determine the additional term by thermodynamic consistency

  24. At the first-order level

  25. At the first-order level

  26. Determine the RG scale For 2-flavors:

  27. Range of the parameters

  28. M-R of compact stars

  29. Summary We study the M-R relation of compact stars considering both perturbation confinement interactions. For parameters With which SQM is absolutely stable, the maximum mass of quark stars can be about two time the solar mass.

  30. A poem to the conference There are compact body in the remote sky. They are fascinlating and so high … Oh, one doesn’t know what they really are, but we can measure the M and R to explore a neutron or quark star. That’s why we are happily here, discussing models and observational data G.X.Peng, 21 Oct. 2014
