The effects of ambipolar diffusion, dust, and ultraviolet radiation in the formation of cores and protostars in interstellar molecular clouds
… takes place within magnetically supported interstellar molecular clouds. The observed inefficiency of star formation in molecular clouds, in which only a small fraction of a cloud's mass is converted into stars, is explained naturally by magnetic support of the envelope and slow, inward …

New Molecular Probes of Astronomical Sources (Interstellar Sources, Comets)
… for refining the knowledge of astronomical molecular sources. The primary project involved HCO in interstellar molecular clouds. The observational results include the verification of the identity of interstellar HCO, the confirmation of the C('+)-HCO correlation first suggested by Snyder, …

Star formation in the presence of magnetic fields: Molecular cloud core formation and dynamical contraction due to ambipolar diffusion; a simulation with axial symmetry
Interstellar molecular clouds are generally believed to be the sites of active star formation in our galaxy. Observed densities, temperatures, and magnetic field strengths imply that well-ordered magnetic fields dominate thermal pressure in supporting these objects against self-gravity. The …

The role of ambipolar diffusion in the formation of interstellar cloud cores and protostars
… a fundamental unsolved problem in astrophysics. Interstellar molecular clouds, observed to be the birth place of stars, have masses much larger than those of typical stars. Observed densities, temperatures, and strengths of well-ordered magnetic fields imply that magnetic forces, transmitted to …

The role of magnetic braking and ambipolar diffusion in the formation of interstellar cloud cores and protostars
The means by which parent molecular clouds give birth to stars constitutes a fundamental unsolved problem in astrophysics. Magnetic fields, which dominate thermal-pressure as a source of support against self-gravity in interstellar molecular clouds, are an important regulator of star-formation. We …
