Scientific paper

We report on observations of TY Corona Australis, a young triple system, with LWS and SWS instruments. Emission bands detected at 3.3, 6.2, 7.7, 8.8, 11.3 and 12.5 μm are attributed to small carbon-rich particles, PAH. [O i] 63 and 146 μm and [C ii] 158 μm emission lines are clearly present. A compact H ii region and a photo-dissociation region (PDR) may explain respectively the presence of the PAH and forbidden emissions. A temperature of 100 K and a density nH = 105-106 cm-3 have been estimated for the PDR. Unlike two others Ae/Be Herbig stars, HD 100546 and HD 142527, TY CrA shows no crystalline silicates in its circumstellar medium; this may suggest an earlier stage of evolution for the system.
