Survivability of planetary systems in young and dense star clusters
Arjen van Elteren, Simon Portegies Zwart, Inti Pelupessy +2
We perform a simulation using the Astrophysical Multipurpose Software Environment of the Orion Trapezium star cluster in which the evolution of the stars and the dynamics of planet…
Gone with the wind: the impact of wind mass transfer on the orbital evolution of AGB binary systems
M. I. Saladino, O. R. Pols, E. van der Helm +2
In low-mass binary systems, mass transfer is likely to occur via a slow and dense stellar wind when one of the stars is in the AGB phase. Observations show that many binaries that…
The consequences of a nearby supernova on the early Solar System
Simon Portegies Zwart, Inti Pelupessy, Arjen van Elteren +2
If the Sun was born in a relatively compact open cluster, it is quite likely that a massive (10MSun) star was nearby when it exploded in a supernova. The repercussions of a superno…
The origin of interstellar asteroidal objects like 1I/2017 U1 'Oumuamua
Simon Portegies Zwart, Santiago Torres, Inti Pelupessy +2
We study the origin of the interstellar object 1I/2017 U1 'Oumuamua by juxtaposing estimates based on the observations with simulations. We speculate that objects like 'Oumuamua ar…
Constraining cloud parameters using high density gas tracers in galaxies
M. V. Kazandjian, I. Pelupessy, R. Meijerink +4
Far-infrared molecular emission is an important tool used to understand the excitation mechanisms of the gas in the inter-stellar medium of star-forming galaxies. In the present wo…
Modelling Mechanical Heating in Star-Forming Galaxies: CO and 13CO Line Ratios as Sensitive Probes
M. V. Kazandjian, I. Pelupessy, R. Meijerink +2
We apply photo-dissociation region (PDR) molecular line emission models, that have varying degrees of enhanced mechanical heating rates, to the gaseous component of simulations of…
