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…

Effect of OH depletion on measurements of the mass-to-flux ratio in molecular cloud cores

K. Tassis, K. Willacy, H. W. Yorke +1

The ratio of mass and magnetic flux determines the relative importance of magnetic and gravitational forces in the evolution of molecular clouds and their cores. Its measurement is…

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…
