Encounters in the ONC - observing imprints of star-disc interactions
C. Olczak, S. Pfalzner, A. Eckart
The external destruction of protoplanetary discs in a clustered environment acts mainly due to two mechanisms: gravitational drag by stellar encounters and evaporation by strong st…
Quasi-binarity of massive stars in young dense clusters - the case of the ONC
S. Pfalzner, C. Olczak
Observations indicate that in young stellar clusters the binary fraction for massive stars is higher than for solar mass stars. For the Orion Nebula Cluster (ONC) there is a binary…
Gravitational Instabilities induced by Cluster Environment? - The encounter-induced angular momentum transfer in discs
S. Pfalzner, C. Olczak
AIM:The aim of this work is to understand to what extend gravitational interactions between the stars in high-density young stellar clusters, like the Orion Nebula Cluster (ONC), c…
The Fate of Discs around Massive Stars in Young Clusters
S. Pfalzner, C. Olczak, A. Eckart
AIMS: The aim of this work is to understand whether there is a difference in the dispersion of discs around stars in high-density young stellar clusters like the Orion Nebula Clust…
Encounter-Triggered Disc Mass Loss in the ONC
C. Olczak, S. Pfalzner, R. Spurzem
The relevance of encounters on the destruction of protoplanetary discs in the Orion Nebula Cluster (ONC) is investigated by combining two different types of numerical simulation. F…
Parameter Study of Star-Discs Encounters
S. Pfalzner, P. Vogel, J. Scharwaechter +1
Interactions between disc-surrounded stars might play a vital role in the formation of planetary systems. Here a first parameter study of the effects of encounters on low-mass disc…
