A triple-induced merger in T Ori C, solves the proplyd lifetime problem and the curiously young shell of M42
Maite Wilhelm, Alessandro Alberto Trani, Simon Portegies Zwart
There has long been a tension between the stellar ages in the Orion Nebula Cluster and the rapid external photoevaporation of its protoplanetary discs. Recently, the shell of the O…
Centrally concentrated star formation in young clusters II: Jet feedback
Adilkhan Assilkhan, Sabrina M. Appel, Bekdaulet Shukirgaliyev +5
Protostellar jets are one of the earliest forms of stellar feedback, but their impact on star formation and cluster assembly in centrally concentrated molecular clouds remains poor…
Kozai-driven mass loss of the circumbinary disk in D9 in orbit around the supermassive black hole Sgr A*
Yannick Badoux, Lucas Pouw, Tim van der Vuurst +1
The supermassive black hole (Sgr A*) in the Galactic center is surrounded by the S-star cluster consisting of young stars on eccentric orbits. Recently, the S-star binary, called D…
The exponential growth of infinitesimal perturbations in the long-term evolution of simulated galaxies
T. Asano, S. Portegies Zwart
Self-gravitating systems of particles are chaotic. We study how chaotic the Galaxy is, and what the consequences are. We therefore simulated the dynamical evolution of a galaxy…
The formation of periodic three-body orbits for Newtonian systems
Simon Portegies Zwart, Arjen Doelman, Jelmer Sein
Braids are periodic solutions to the general N-body problem in gravitational dynamics. These solutions seem special and unique, but they may result from rather usual encounters bet…
Ripples spreading across the Galactic disc. Interplay of direct and indirect effects of the Sagittarius dwarf impact
Tetsuro Asano, Michiko S. Fujii, Junichi Baba +2
Gaia data have revealed vertically asymmetric phase-space structures in the Milky Way (MW) disc, such as phase spirals, indicating vertical oscillations. These oscillations exhibit…
