Slowly rotating Black Holes in DHOST Theories
This research finds analytical solutions for slowly rotating black holes in Degenerate Higher Order Scalar Tensor (DHOST) theories, which are modified gravity frameworks that differ from General Relativity. The study successfully derives an explicit form for the frame-dragging function, showing how rotation affects orbital parameters like the Innermost Stable Circular Orbit (ISCO). This provides new insights into astrophysical phenomena and gravitational wave data.
