Non-conservative effects on Spinning Black Holes from World-Line Effective Field Theory

TL;DR

This paper extends the worldline effective field theory to include non-conservative tidal effects on spinning black holes, providing new equations of motion and power loss results relevant for binary inspirals.

Contribution

It introduces a generalized formalism that captures non-conservative effects for spinning black holes to all orders in spin, including new equations of motion and power loss calculations.

Findings

Agreement with previous mass and angular momentum change calculations

New non-conservative equations of motion for binary inspirals

Power loss/gain results starting at 5PN and 2.5PN order

Abstract

We generalize the worldline EFT formalism developed in [4-9] to calculate the non-conservative tidal effects on spinning black holes in a long wavelength approximation that is valid to all orders in the magnitude of the spin. We present results for the rate of change of mass and angular momentum in a background field and find agreement with previous calculations obtained by different techniques. We also present new results for both the non-conservative equations of motion and power loss/gain for a binary inspiral, which start at 5PN and 2.5PN order respectively and manifest the Penrose process.
