Filaments in creation's heart
Article Abstract:
Gravity and external forces form a system of dense filaments of molecular gas, leading to the formation of stars in the constellation of Orion. Orion contains highly dense molecular clouds, especially behind the Great Nebula. Gravity causes the collapse of a 3-dimensional cloud into a sheet, allowing the formation of filamentary structures. External forces, such as planar shocks, form filaments by hitting a massive cloud and compressing it into a sheet. The anisotropic feature of magnetic field further collapse the sheet into filaments.

Coexisting conical bipolar and equatorial outflows from a high-mass protostar
Article Abstract:
The BN/KL area in the Orion molecular cloud is a model for the study of star formation. The main source of outflow in the BN/KL area could be an object termed radio source I, which is thought to be surrounded by rotating molecular material. High-resolution observations of silicon monoxide (SiO) and water maser emission are reported from gas around source I, and it is shown that the area is dominated by a conical bipolar outflow within 60 AU of the source.

Shocking behaviour of young stars in Orion
Article Abstract:
Star-forming regions in thick molecular clouds exhibit the reaction of steady stellar winds with molecular clouds that produce hydrodynamic shock fronts at supersonic speeds. This potent occurence produces an H-H like (Herbig-Haro) spectra. The H-H objects were produced by jet-cloud interactions to radiation behind the shockwave. Iron and oxygen emmissions are created beneath the shocks .
