Spontaneous vs. Triggered Star Formation
• Most star formation begins due to spontaneous processes on a galactic scale, given sufficient time and material free fall will result in star formation.
• An outside source of energy can trigger the formation of a star before conditions become sufficient for free fall, leaving sequentially younger stars in its path while clouds broken into filaments by magnetic fields will show a filamentary pattern of protostars.
Star formation in a “controlled” environment
• small regions where the formation conditions except for the trigger are the same
• physical and geographical characteristics of protostars created can therefore be related to triggering mechanism.
NGC 281
• HII emission containing the young galactic cluster IC 1590, OB star trapezium system HD5005 with what appears to be two distinct start forming regions around it;
• Triggered East side with “pillars of creation”, newborn stars as a result of triggering from the nearby OB star trapezium system.
• Crowded West side with three distinct clumps (NE, NW and S) of star formation.
