The binarity of the local white dwarf population

- S. Toonen, M. Hollands, B. Gaensicke, T. Boekholt
- Physics
- 20 March 2017

Context
As endpoints of stellar evolution, white dwarfs (WDs) are powerful tools to study the evolutionary history of the Galaxy. In particular, the multiplicity of WDs contains information… Expand

Formation of massive seed black holes via collisions and accretion

- T. Boekholt, D. Schleicher, +4 authors L. Haemmerlé
- Physics
- 17 January 2018

Models aiming to explain the formation of massive black hole seeds, and in particular the direct collapse scenario, face substantial difficulties. These are rooted in rather ad hoc and fine-tuned… Expand

A Keplerian-based Hamiltonian splitting for gravitational N-body simulations

- G. Ferrari, T. Boekholt, +6 authors Brazil
- Physics
- 13 February 2014

We developed a Keplerian-based Hamiltonian splitting for solving the gravitational $N$-body problem. This splitting allows us to approximate the solution of a general $N$-body problem by a… Expand

Newton vs the machine: solving the chaotic three-body problem using deep neural networks

Collisions in primordial star clusters

- B. Reinoso, D. Schleicher, M. Fellhauer, R. Klessen, T. Boekholt
- PhysicsAstronomy & Astrophysics
- 18 January 2018

Collisions were suggested to potentially play a role in the formation of massive stars in present day clusters, and have likely been relevant during the formation of massive stars and intermediate… Expand

The evolution of the Sun's birth cluster and the search for the solar siblings with Gaia

- C. A. Mart'inez-Barbosa, A.G.A. Brown, T. Boekholt, S. Zwart, E. Antiche, T. Antoja
- Physics
- 4 January 2016

We use self-consistent numerical simulations of the evolution and disruption of the Sun's birth cluster in the Milky Way potential to investigate the present-day phase space distribution of the Sun's… Expand

The origin of chaos in the orbit of comet 1P/Halley

- T. Boekholt, F. I. Pelupessy, D. Heggie, S. Zwart
- Physics
- 22 June 2016

According to Munoz-Gutierrez et al. (2015) the orbit of comet 1P/Halley is chaotic with a surprisingly small Lyapunov time scale of order its orbital period. In this work we analyse the origin of… Expand

On the reliability of N-body simulations

- T. Boekholt, S. P. Portegies Zwart
- Mathematics, Physics
- 24 November 2014

The general consensus in the N-body community is that statistical results of an ensemble of collisional N-body simulations are accurate, even though individual simulations are not. A way to test this… Expand
