Cosmic Jazz: Three Finales of an Encounter with a Black Hole
Original: "Three body Simulations of a Primordial Black Hole Encounter with the TOI 2796 System"
The gravitational improvisation of a star, a hot Jupiter, and a primordial black hole plays out in three notes: ejection, trio, and abduction.

A black hole from the dawn of time flies past a distant star. Its gravity plays jazz — and in one improvisation, a planet is hurled into interstellar darkness; in another, three bodies freeze into a stable rhythm. And a neural network found the third option: the black hole leads the planet away on an eternal journey. We stand on the threshold of a new astronomy — the search for orbital notes played by dark matter.
🎯 In the capture scenario, planet TOI-2796 b circled the black hole on an orbit with a radius of 0.0194 AU — three times tighter than Mercury's orbit.
\ddot{\mathbf{r}}_i = \sum_{j \neq i} \frac{G m_j (\mathbf{r}_j - \mathbf{r}_i)}{|\mathbf{r}_j - \mathbf{r}_i|^3}
Equation of motion for the gravitational N-body problem, where the fate of each object depends on the positions of all others.
R_s = \frac{2GM}{c^2}
The point of no return, delineating the region from which not even light can escape.
