Oscillating Filaments: I - Oscillation and Geometrical Fragmentation
Matthias Gritschneder, Stefan Heigl, Andreas Burkert
We study the stability of filaments in equilibrium between gravity and internal as well as external pressure using the grid based AMR-code RAMSES. A homogeneous, straight cylinder…
The Pillars of Creation revisited with MUSE: gas kinematics and high-mass stellar feedback traced by optical spectroscopy
A. F. Mc Leod, J. E. Dale, A. Ginsburg +4
Integral field unit (IFU) data of the iconic Pillars of Creation in M16 are presented. The ionisation structure of the pillars was studied in great detail over almost the entire vi…
The Return of the Proplyds - Understanding the Dynamics of Ionization Triggered Stars
Matthias Gritschneder, Andreas Burkert
Proplyds and stars inside HII-regions are a well studied phenomenon. It is possible that they were triggered by the expansion of the HII-region itself. Here, we present calculation…
The role of theta Oph in the formation and evolution of the Pipe Nebula - is star formation ever isolated?
Matthias Gritschneder, Douglas N. C. Lin
We propose that the Pipe Nebula is an HII region shell swept up by the B2 IV beta Cephei star theta Ophiuchi. After reviewing the morphological evidence by recent observations, we…
Detailed Numerical Simulations on the Formation of Pillars around HII-regions
Matthias Gritschneder, Andreas Burkert, Thorsten Naab +1
We study the structural evolution of turbulent molecular clouds under the influence of ionizing radiation emitted from a nearby massive star by performing a high resolution paramet…
Protostellar discs formed from turbulent cores
S. Walch, T. Naab, A. Burkert +2
We investigate the collapse and fragmentation of low-mass, trans-sonically turbulent prestellar cores, using SPH simulations. The initial conditions are slightly supercritical Bonn…
