Non-ideal MHD simulations of subcritical prestellar cores with non-equilibrium chemistry
Aris Tritsis, Christoph Federrath, Karen Willacy +1
Non-ideal magnetohydrodynamic (MHD) effects are thought to be gravity's closest ally in overcoming the support of magnetic fields and in forming stars. Here, we modify the publicly…
A new method for probing magnetic field strengths from striations in the interstellar medium
Aris Tritsis, Christoph Federrath, Nicola Schneider +1
Recent studies of the diffuse parts of molecular clouds have revealed the presence of parallel, ordered low-density filaments termed striations. Flows along magnetic field lines, K…
Python Radiative Transfer Emission code (PyRaTE): non-LTE spectral lines simulations
Aris Tritsis, Harold W. Yorke, Konstantinos Tassis
We describe PyRaTE, a new, non-local thermodynamic equilibrium (non-LTE) line radiative transfer code developed specifically for post-processing astrochemical simulations. Populati…
Chemistry as a diagnostic of prestellar core geometry
A. Tritsis, K. Tassis, K. Willacy
We present a new method for assessing the intrinsic 3D shape of prestellar cores from molecular column densities. We have employed hydrodynamic simulations of contracting, isotherm…
A search for co-evolving ion and neutral gas species in prestellar molecular cloud cores
Konstantinos Tassis, Talayeh Hezareh, Karen Willacy
Comparison of linewidths of spectral line profiles of ions and neutral molecules have been recently used to estimate the strength of the magnetic field in turbulent star-forming re…
Non-Equilibrium Chemistry of Dynamically Evolving Prestellar Cores: II. Ionization and Magnetic Field
Konstantinos Tassis, Karen Willacy, Harold W. Yorke +1
We study the effect that non-equilibrium chemistry in dynamical models of collapsing molecular cloud cores has on measurements of the magnetic field in these cores, the degree of i…
