# Modelling general-relativistic disk in OJ 287

## TL;DR

This paper models self-gravitating, general-relativistic disks around the primary black hole in OJ 287, aiming to explain its observational features through relativistic hydrodynamics of the binary system.

## Contribution

It introduces a consistent general-relativistic model of accretion disks in the OJ 287 binary system, aligning with observed density and geometric constraints.

## Key findings

- Disk models satisfy key observational constraints.
- Relativistic hydrodynamics can explain OJ 287's features.
- Potential to reproduce observed phenomena through these models.

## Abstract

We model self-gravitating disks in Keplerian motion around the primary black hole, in the binary black hole system OJ 287 with a torus, employing a consistently general-relativistic approach. They satisfy geometric and/or mass density requirements found by Sillanpaa, Valtonen, Lehto and their coworkers. It is plausible that essential observational features of OJ 287 can be obtained via the general-relativistic description of the Bondi-Hoyle-Lyttleton transits through these tori, within the framework of radiation hydrodynamics.
