Detecting the tidal heating with the generic extreme-mass-ratio inspirals

Understand

The horizon of a classical black hole (BH), functioning as a one-way membrane, plays a vital role in the dynamic evolution of binary BHs, capable of absorbing fluxes entirely.

• Tidal heating, stemming from this phenomenon, exerts a notable influence on the production of gravitational waves(GWs).
• If at least one member of a binary is an exotic compact object (ECO) instead of a BH, the absorption of fluxes is expected to be incomplete and the tidal heating would be different.
• Thus, tidal heating can be utilized for model-independent investigations into the nature of compact object.
