Massive Neutron Stars with Hadron-Quark Transition Core : phenomenological approach by "3-window model"
Tatsuyuki Takatsuka, Kota Masuda, Tetsuo Hatsuda
By a new approach introducing a "3-window model" and constructing phenomenologically an equation of state for the hadron-quark (HQ) transition region, possible maximum mass of neut…
Hyperon Puzzle, Hadron-Quark Crossover and Massive Neutron Stars
Kota Masuda, Tetsuo Hatsuda, Tatsuyuki Takatsuka
Bulk properties of cold and hot neutron stars (NSs) are studied on the basis of the hadron-quark crossover picture where a smooth transition from the hadronic phase to the quark ph…
Hadron-Quark Crossover and Hot Neutron Stars at Birth
Kota Masuda, Tetsuo Hatsuda, Tatsuyuki Takatsuka
We construct a new isentropic equation of state (EOS) at finite temperature "CRover" on the basis of the hadron-quark crossover at high density. By using the new EOS, we study the…
Massive Hybrid Stars with Strangeness
Tatsuyuki Takatsuka, Tetsuo Hatsuda, Kota Masuda
How massive the hybrid stars could be is discussed by a "3-window model" proposed from a new strategy to construct the equation of state with hadron-quark transition. It is found t…
Hadron-Quark Crossover and Massive Hybrid Stars
Kota Masuda, Tetsuo Hatsuda, Tatsuyuki Takatsuka
On the basis of the percolation picture from the hadronic phase with hyperons to the quark phase with strangeness, we construct a new equation of state (EOS) with the pressure inte…
Hadron-Quark Crossover and Massive Hybrid Stars with Strangeness
Kota Masuda, Tetsuo Hatsuda, Tatsuyuki Takatsuka
Using the idea of a smooth crossover from the hadronic matter with hyperons to quark matter with strangeness, we show that the maximum mass of neutron stars with quark matter core…
