Detection of the unusual 3.5µm feature in the Herbig Be star MWC 297.
TERADA H., IMANISHI M., GOTO M. and MAIHARA T.
Abstract (from CDS):
We present spectroscopic observations of MWC 297 with medium spectral resolution in the 2.1-4.1µm region, that show the unusual emission band at 3.53µm as well as gaseous emission lines of the Brackett, Pfund and Humphrey series of hydrogen. A unique aspect of the measured 3.53µm emission band is the fact that, within our detection limit, it is not accompanied by the 3.3 and 3.4µm emission band. We suggest that the 3.53µm feature could be emitted by highly dehydrogenized carbonaceous dust particles that were processed under the influence of the strong radiation field of the central star.
