We study the thermodynamic properties of asymmetric quark matter and large mass quark stars within the confined-isospin-density-dependent-quark-mass model. We find that the quark matter symmetry energy should be very large in order to describe the recent discovered heavy compact stars PSR J0348+0432 ( $$\text {2.01}\pm \text {0.04}M_{\odot }$$ ), MSP J0740+6620 ( $$\text {2.14}\pm ^\text {0.10}_\text {0.09}M_{\odot }$$ of 68.3 $$\%$$ credibility interval and $$\text {2.14}\pm ^\text {0.20}_\text {0.18}M_{\odot }$$ of 95.4 $$\%$$ credibility in...
