Tidal-heating and viscous dissipation correspondence in black holes and viscous compact objects

The effect of energy absorption during the binary evolution Exotic-compact-objects (ECOs) is extensively studied. We review underlying mechanism that provides dissipation in material objects - tidal friction. show unlike typical astrophysical objects, where due to viscosity negligible, ECOs, could potentially mimic analogous black-holes (BHs) heating. stand for their differences and similarities context inspiral. Inspired by membrane paradigm recent studies, we demonstrate how a defining feature quantifies close ECO classical BH absorption. can induce significant modifications GW waveform, which some favorable scenarios super-massive binaries equal mass spin, enables measurement future precision gravitational-wave (GW) observations. Finally, discuss implications on reflection coefficient relation universal volume entropy bound.
