| Abstract: |
We summarize the work done in the last decade on characterizing
magnetic fields in star-forming regions using the comparison of spectral lines
from coexistent ion and neutral molecular species. We discuss how the
presence of magnetic fields was originally deduced observationally
through the relative narrowing of ion spectral line profiles, and the
relationship of this narrowing to the inclination of the magnetic field to the line of sight.
We also briefly describe the more recent work of
Li & Houde (2008) where the same effect was
analyzed through the comparison of the characteristics of the
turbulence power spectra of coexistent ions and neutrals, and its
implication for the determination of the inclination angle. |
