abstract

In this paper, we present the first results of a survey of 220 starless cores selected primarily by their optical obscuration (Lee & Myers 1999) and observed in CS (2-1), N$_2$H$^+$ (1-0), and C$^{18}$O (1-0) using the NEROC Haystack 37-m telescope, to quantify the incidence of infall motions toward starless cores and find infall candidates for further study in the future.

  1. Chemical diversity of dense cores in Orion B: The role of the environment

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    PCA of 25 molecular lines across 1001 Orion B cores reveals that chemical diversity is driven by column density, the FUV-to-density ratio G0/n, and freeze-out signatures tied to mean density.
