Studies will be conducted to explore (1) the fundamental parameters controlling the determination of individual stellar masses and star system properties in the process of star formation; (2) the birth of typical star clusters in regions of dense gas accretion, accounting for the harassment, stirring, and removal of material by protostellar jets and winds; (3) the fiery creation of massive star and globular clusters, including the winds, radiation pressure, and ionizing photons interacting with turbulent and clumpy environs; and (4) explosions which result from the collapse of stars in the creation of gamma-ray bursts, including newly-discovered varieties of weak GRB and x-ray flash transients.

研究将探索(1)在恒星形成过程中控制单个恒星质量和恒星系统性质确定的基本参数；(2)在密集气体吸积区域中典型星团的诞生，这是由于原恒星喷流和风对物质的骚扰、搅拌和移除；(3)大质量恒星和球状星团的炽热形成，包括风、辐射压力和电离光子与湍流和块状环境的相互作用；(4)在伽玛射线暴产生过程中由恒星坍缩引起的爆炸，包括新发现的各种弱伽玛射线暴和x射线闪光瞬变。
