摘  要: Our understanding of low-mass star formation has made significant process in recent years. In practice, however, many key problems, e.g., how a prestellar core evolves and forms a protostar, what makes a prestellar core fragment in the collapse phase, and what is the driving mechanism of molecular outflows, are still poorly known. In an effort to address these issues, we have started a systematic program to observe, at high angular resolution, a number of low-mass (pre-)protostellar cores, using large interferometric arrays (e.g., SMA, IRAM-PdBI, ATCA, and OVRO). In this talk I present the preliminary results of this program.
