Chemistry and IR emission of acetylene in planet-forming regions of T Tauri disks. Impact of elemental abundances and dust properties

Pacôme Estève, Benoît Tabone, Emilie Habart +5

(Abridged) We aim to explore the parameters that influence the mid-infrared emission of C${}_2$H${}_2$ and H${}_2$O, and if the spread observed in $F{}_{{\mathrm{C}}_2{\mathrm{H}}_2}$/$F{}_{{\mathrm{H}}_2\mathrm{O}}$ is tr…
