Cradle(s) of the Sun
Susanne Pfalzner, Kirsten Vincke
The Sun likely formed as part of a group of stars. A close stellar flyby by one of the solar siblings is probably responsible for the sharp outer edge in the solar system`s mass di…
How do disks and planetary systems in high-mass open clusters differ from those around field stars?
Kirsten Vincke, Susanne Pfalzner
Only star clusters that are sufficiently compact and massive survive largely unharmed beyond 10 Myr. However, their compactness means a high stellar density which can lead to stron…
Outer solar system possibly shaped by a stellar fly-by
Susanne Pfalzner, Asmita Bhandare, Kirsten Vincke +1
The planets of our solar system formed from a gas-dust disk. However, there are some properties of the solar system that are peculiar in this context. First, the cumulative mass of…
Did a stellar fly-by shape the planetary system around Pr 0211 in the cluster M 44?
Susanne Pfalzner, Asmita Bhandare, Kirsten Vincke
Out of the 3000 exoplanets detected so far, only fourteen planets are members of open clusters: among them an exoplanet system around Pr 0211 in the cluster M44 which consis…
From star-disc encounters to numerical solutions for a subset of the restricted three-body problem
Andreas Breslau, Kirsten Vincke, Susanne Pfalzner
Various astrophysical processes are known, where the fly-by of a massive object affects matter initially supported against gravity by rotation. Examples are perturbations of galaxi…
Cluster dynamics largely shapes protoplanetary disc sizes
Kirsten Vincke, Susanne Pfalzner
It is still on open question to what degree the cluster environment influences the sizes of protoplanetary discs surrounding young stars. Particularly so for the short-lived cluste…
Strong effect of the cluster environment on the size of protoplanetary discs?
Kirsten Vincke, Andreas Breslau, Susanne Pfalzner
Context. Most stars are born in clusters, thus the protoplanetary discs surrounding the newly formed stars might be influenced by this environment. Isolated star-disc encounters ha…
Which young clusters/associations are we missing today?
Susanne Pfalzner, Kirsten Vincke, Mai Xiang
Currently clusters/associations of stars are mainly detected as surface density enhancements relative to the background field. While clusters form, their surface density increases.…
Sizes of protoplanetary discs after star-disc encounters
Andreas Breslau, Manuel Steinhausen, Kirsten Vincke +1
Most stars do not form in isolation, but as part of a star cluster or association. These young stars are initially surrounded by protoplanetary discs. In these cluster environments…
