How to Identify the Object with a Mass Range of (2.2–3) M⊙ in the Merger of Compact Star Systems

High-frequency gravitational-wave (GW) radiation has been detected by LIGO-Virgo-KAGRA in the merger of compact stars. However, in two GW events, GW190814 and GW200210, the mass of one companion object falls into the mass region of (2.2–3) M _⊙ , and how to identify such an object (e.g., as a low-ma...
