      Prestellar cores are self-gravitating dense and cold structures within molecular clouds where future stars are born. They are expected, at the stage of transitioning to the protostellar phase, to harbor centrally concentrated ...

      Protostellar outflows and jets play a vital role in star formation as they carry away excess angular momentum from the inner disk surface, allowing the material to be transferred toward the central protostar. Theoretically, ...

      Luo, Qiu-yi; Liu, Tie; Tatematsu, Ken'ichi; Liu, Sheng-Yuan; Li, Pak Shing; Di Francesco, James; Johnstone, Doug; Goldsmith, Paul F.; Dutta, Somnath; Hirano, Naomi; Lee, Chin-Fei; Li, Di; Kim, Kee-Tae; Lee, Chang Won; Lee, Jeong-Eun; Liu, Xun-chuan; Juvela, Mika; He, Jinhua; Qin, Sheng-Li; Liu, Hong-Li; Eden, David; Kwon, Woojin; Sahu, Dipen; Li, Shanghuo; Xu, Feng-Wei; Zhang, Si-ju; Hsu, Shih-Ying; Bronfman Aguiló, Leonardo Jaime; Sanhueza, Patricio; Pelkonen, Veli-Matti; Zhou, Jian-wen; Liu, Rong; Gu, Qi-lao; Wu, Yue-fang; Mai, Xiao-feng; Falgarone, Edith; Shen, Zhi-Qiang (IOP, 2022)
      During the transition phase from a prestellar to a protostellar cloud core, one or several protostars can form within a single gas core. The detailed physical processes of this transition, however, remain unclear. We present ...
