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, isothermal cores considering three intrinsic geometries: spherical, cylindrical/filamentary and disk-like. We have coupled our hydrodynamic simulations with non-equilibrium chemistry. We find that a) when cores are observed very elongated (i.e. for aspect ratios $\le$ 0.15) the intrinsic 3D geometry can be probed by their 2D… 
ENABLING STAR FORMATION VIA SPONTANEOUS MOLECULAR DIPOLE ORIENTATION IN ICY SOLIDS
It is shown here how new experimental data, for the electrical properties of solid CO, can be used to fill important gaps in our understanding of the evolution of prestellar cores. Dust grains with a
Striations in molecular clouds: streamers or MHD waves?
Dust continuum and molecular observations of the low column density parts of molecular clouds have revealed the presence of elongated structures which appear to be well aligned with the magnetic

Shapes of Molecular Cloud Cores and the Filamentary Mode of Star Formation
Using recent dust continuum data, we generate the intrinsic ellipticity distribution of dense, starless molecular cloud cores. Under the hypothesis that the cores are all either oblate or prolate
COMPARISON OF PRESTELLAR CORE ELONGATIONS AND LARGE-SCALE MOLECULAR CLOUD STRUCTURES IN THE LUPUS I REGION
Turbulence and magnetic fields are expected to be important for regulating molecular cloud formation and evolution. However, their effects on sub-parsec to 100 parsec scales, leading to the formation
An analytic column density profile to fit prestellar cores
ABSTRACT We present a new analytical three-parameter formula to fit observed column den-sity profiles of prestellar cores. It represents a line-of-sight integral through a spher-ically symmetric or
NON-EQUILIBRIUM CHEMISTRY OF DYNAMICALLY EVOLVING PRESTELLAR CORES. II. IONIZATION AND MAGNETIC FIELD
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 ionization, and the
Dynamic Cores in Hydrostatic Disguise
We discuss the column density profiles of "cores" in three-dimensional smoothed particle hydrodynamics (SPH) numerical simulations of turbulent molecular clouds. The SPH scheme allows us to perform a
The shapes of molecular cloud cores in Orion
We investigate the intrinsic shapes of starless cores in the Orion giant molecular cloud, using the pre-stellar core sample of Nutter & Ward-Thompson, which is based on submillimetre SCUBA data. We
Molecular Evolution in Collapsing Prestellar Cores
We have investigated the evolution and distribution of molecules in collapsing prestellar cores via numerical chemical models, adopting the Larson-Penston solution and its delayed analogs to study
Why do starless cores appear more flattened than protostellar cores
We evaluate the intrinsic three-dimensional shapes of molecular cores, by analysing their projected shapes. We use the recent catalogue of molecular line observations of Jijina et al. and model the
Formation and Collapse of Nonaxisymmetric Protostellar Cores in Planar Magnetic Molecular Clouds
We extend our earlier work on ambipolar diffusion-induced formation of protostellar cores in isothermal sheetlike magnetic interstellar clouds by studying nonaxisymmetric collapse for the physically
NON-EQUILIBRIUM CHEMISTRY OF DYNAMICALLY EVOLVING PRESTELLAR CORES. I. BASIC MAGNETIC AND NON-MAGNETIC MODELS AND PARAMETER STUDIES
We combine dynamical and non-equilibrium chemical modeling of evolving prestellar molecular cloud cores and investigate the evolution of molecular abundances in the contracting core. We model both
