摘要: We present 3D simulations of a system four neutral clumps embedded in photoionized region. In this system, we have three small which partially shield single, larger clump from the stellar ionizing photons. This flow evolves to form structure with main body and ‘columns’ pointing towards central star. Qualitatively, similar structures are seen ‘Finger’ Carina Nebula.
