Our work shows that state-of-the-art relativistic mean field models can generate massive stars reaching $\\gtrsim 2.05\\,\\Msun$, while being in good agreement with gravitational-wave events and x-ray pulsar observations, when quark vector interactions and non-standard self-vector interactions are introduced.
