The mass distribution of stellar mergers: A new scenario for several FS CMa stars
N. Dvořáková, D. Korčáková, F. Dinnbier +1
(Abreviated) FS CMa stars belong to a diverse group of stars exhibiting the B[e] phenomenon, which is manifested mainly by the presence of forbidden emission lines and a~strong inf…
Do the majority of stars form as gravitationally unbound?
František Dinnbier, Pavel Kroupa, Richard I. Anderson
Some of the youngest stars (age Myr) are clustered, while many others are observed scattered throughout star forming regions or in complete isolation. It has been int…
Estimating the ages of open star clusters from properties of their extended tidal tails
František Dinnbier, Pavel Kroupa, Ladislav Šubr +1
The most accurate current methods for determining the ages of open star clusters, stellar associations and stellar streams are based on isochrone fitting or the lithium depletion b…
Tree-based solvers for adaptive mesh refinement code FLASH -- II: radiation transport module TreeRay
Richard Wünsch, Stefanie Walch, František Dinnbier +5
The treatment of radiative transfer with multiple radiation sources is a critical challenge in simulations of star formation and the interstellar medium. In this paper we present t…
SILCC VI -- Multi-phase ISM structure, stellar clustering, and outflows with supernovae, stellar winds, ionising radiation and cosmic rays
Tim-Eric Rathjen, Thorsten Naab, Philipp Girichidis +6
We present simulations of the multi-phase interstellar medium (ISM) at solar neighbourhood conditions including thermal and non-thermal ISM processes, star cluster formation, and f…
How fast do young star clusters expel their natal gas?: Estimating the upper limit of the gas expulsion time-scale
F. Dinnbier, S. Walch
Formation of massive stars within embedded star clusters starts a complex interplay between their feedback, inflowing gas and stellar dynamics, which often includes close stellar e…
Tidal tails of open star clusters as probes to early gas expulsion II: Predictions for Gaia
František Dinnbier, Pavel Kroupa
We study the formation and evolution of the tidal tail released from a young Pleiades-like star cluster, due to expulsion of primordial gas in a realistic gravitational field of th…
Tidal tails of open star clusters as probes to early gas expulsion I: A semi-analytic model
František Dinnbier, Pavel Kroupa
Star clusters form out of the densest parts of infrared dark clouds. The emergence of massive stars expels the residual gas, which has not formed stars yet. Gas expulsion lowers th…
A MODEST review
Anna Lisa Varri, Maxwell Xu Cai, Francisca Concha-Ramírez +7
We present an account of the state of the art in the fields explored by the research community invested in 'Modeling and Observing DEnse STellar systems'. For this purpose, we take…
SILCC-ZOOM: The early impact of ionizing radiation on forming molecular clouds
Sebastian Haid, Stefanie Walch, Daniel Seifried +3
As part of the SILCC-ZOOM project we present our first sub-parsec resolution radiation-hydrodynamic simulations of two molecular clouds self-consistently forming from a turbulent,…
Evidence for feedback and stellar-dynamically regulated bursty star cluster formation: the case of the Orion Nebula Cluster
Pavel Kroupa, Tereza Jerabkova, František Dinnbier +2
(abridged) A scenario for the formation of multiple co-eval populations separated in age by about 1 Myr in very young clusters (VYCs, ages less than 10 Myr) and with masses in the…
Nature of the Galactic centre NIR-excess sources. I. What can we learn from the continuum observations of the DSO/G2 source?
Michal Zajaček, Silke Britzen, Andreas Eckart +9
The Dusty S-cluster Object (DSO/G2) orbiting the supermassive black hole (Sgr A*) in the Galactic centre has been monitored in both near-infrared continuum and line emission. There…
Fragmentation of vertically stratified gaseous layers: monolithic or coalescence-driven collapse
František Dinnbier, Richard Wünsch, Anthony P. Whitworth +1
We investigate, using 3D hydrodynamic simulations, the fragmentation of pressure-confined, vertically stratified, self-gravitating gaseous layers. The confining pressure is either…
Abundance analysis of DAZ white dwarfs
Adela Kawka, Stephane Vennes, Frantisek Dinnbier +2
We present an abundance analysis of a sample of 33 hydrogen-rich (DA) white dwarfs. We have used archival high-resolution spectra to measure abundances of calcium, magnesium and ir…
