Magnetic Field Structure in Spheroidal Star-Forming Clouds. II. Estimating Field Structure from Observed Maps
Philip C. Myers, Ian W. Stephens, Sayantan Auddy +3
This paper presents models to estimate the structure of density and magnetic field strength in spheroidal condensations, from maps of their column density and their polarization of…
Magnetic Field Structure of Dense Cores using Spectroscopic Methods
Sayantan Auddy, Philip C. Myers, Shantanu Basu +3
We develop a new ''core field structure'' (CFS) model to predict the magnetic field strength and magnetic field fluctuation profile of dense cores using gas kinematics. We use spat…
Magnetic Field Structure in Spheroidal Star-Forming Clouds
Philip C. Myers, Shantanu Basu, Sayantan Auddy
A model of magnetic field structure is presented to help test the prevalence of flux freezing in star-forming clouds of various shapes, orientations, and degrees of central concent…
From Molecular Clouds to the IMF: Spatial and Temporal Effects
Shantanu Basu, Sayantan Auddy
We review star formation in molecular clouds and describe why magnetic fields may be important and how they can influence filamentary structure and the column density probability d…
The Effect of Magnetic Fields and Ambipolar Diffusion on the Column Density Probability Distribution Function in Molecular Clouds
Sayantan Auddy, Shantanu Basu, Takahiro Kudoh
Simulations generally show that non-self-gravitating clouds have a lognormal column density () probability distribution function (PDF), while self-gravitating clouds with active…
Magnetic Ribbons: A Minimum Hypothesis Model for Filaments
Sayantan Auddy, Shantanu Basu, Takahiro Kudoh
We develop a magnetic ribbon model for molecular cloud filaments. These result from turbulent compression in a molecular cloud in which the background magnetic field sets a preferr…
