We have investigated the properties of strange quark matter and quark stars at finite temperature within the confined isospin-density-dependent mass (CIDDM) model. The newly discovered heavy compact stars PSR J0348+0432 ( 2.01±0.04  M⊙) and MSP J0740+6620 ( 2.14±0.090.10  M⊙ of 68.3% credibility interval and 2.14±0.180.20  M⊙ of 95.4% credibility interval) can be well described as quark stars with large quark matter symmetry energy within the CIDDM model in this work. In particular, we also calculate the properties of the protoquark...
