The velocity integrated maps and spatial averaged spectra of C4H 9–8, c-C3H2 2–1 and H13CO+ 1–0. The source names are presented in the maps and spectra. The gray scale color at the right is in units of K km s−1 . (a): The velocity integrated intensity maps for C4H 9–8 (magenta contours), c-C3H2 2–1 (blue contours) and H13CO+ 1–0 (green contours) of G001.38+20. (b): The same as Figure 1(a) but for G001.84+16. (c): Spectra of C4H at 85672.5793 MHz, c-C3H2 at 85338.8940 MHz and H13CO+ at 86754.2884 MHz in the yellow box of G001.38+20. (d): The same as Figure 1(c) but for G001.84+16. The detailed mapping information of all sources for C4H 9–8, c-C3H2 2–1 and H13CO+ 1–0 are listed in Table 4. -- astro-ph.GA

Spatial Distribution of C4H and c-C3H2 in Cold Molecular Cores

by Keith CowingJuly 3, 2024July 1, 2024

C4H and c-C3H2, as unsaturated hydrocarbon molecules, are important for forming large organic molecules in the interstellar medium. We present mapping observations of C4H (N=9−8) lines, c-c-C3H2 (JKa,Kb=21,2-10,1) %at 85338.894 […]
