Can we observe the ion-neutral drift velocity in prestellar cores?
Autor: Aris Tritsis, Shantanu Basu, Christoph Federrath
Given the low ionization fraction of molecular clouds, ambipolar diffusion is thought to be an integral process in star formation. However, chemical and radiative-transfer effects, observational challenges, and the fact that the ion-neutral drift vel

The initial magnetic criticality of prestellar cores
Autor: Felix D Priestley, Charles Yin, James Wurster
Direct observational measurements of the magnetic field strength in prestellar cores typically find supercritical mass-to-flux ratios, suggesting that the magnetic field is insufficient to prevent gravitational collapse. These measurements suffer fro

Dynamics of magnetic flux tubes in accretion disks of Herbig Ae/Be stars
Autor: Sergey A. Khaibrakhmanov, Alexander E. Dudorov
Publikováno v: Open Astronomy
The dynamics of magnetic flux tubes (MFTs) in the accretion disk of typical Herbig Ae/Be star with fossil large-scale magnetic field is modeled taking into account the buoyant and drag forces, radiative heat exchange with the surrounding gas, and the

Investigating the role of magnetic fields in star formation using molecular line profiles
Autor: F. D. Priestley, Charles Yin, James Wurster
Determining the importance of magnetic fields in star forming environments is hampered by the difficulty of accurately measuring both field strength and gas properties in molecular clouds. We post-process three-dimensional non-ideal magnetohydrodynam

[Context] Magnetic fields are predicted to play a significant role in the formation of filamentary structures and their fragmentation to form stars and star clusters.
[Aims] We aim to investigate the role of the magnetic field in the process of

The six parameters of the standard ΛCDM model have best-fit values derived from the Planck temperature power spectrum that are shifted somewhat from the best-fit values derived from WMAP data. These shifts are driven by features in the Planck temper
