Title: Witnessing the fragmentation of a filament into prestellar cores in Orion B/NGC~2024

Abstract: Herschel observations of nearby clouds have shown that filamentary structures are ubiquitous and that most prestellar cores form in filaments. Thus, probing the fragmentation of filaments into cores is crucial to improve our observational understanding of the star formation process. We mapped the Orion B/NGC 2024 region in H13CO+ (1–0) to investigate how observed filaments are fragmenting into cores. To gain the kinematic evidence of the filament fragmentation, we compare the centroid velocity distribution with the column density distribution and conducted the velocity structure-function analysis. I will discuss these results in detail.
