Extended red emission ( ERE ) detected in the 30 Doradus nebula ?

چکیده
We present low-dispersion visible spectra of two regions of the 30 Doradus nebula. When corrected for atomic continuum emission and divided by the spectrum of the exciting and illuminating stars, one of the two spectra clearly shows Extended Red Emission (ERE) superimposed on the scattering component. This ERE band peaks around 7270Å and is 1140Å width. HAC grains are found to explain the observed spectra in terms of scattering and luminescence.

متن کاملThe ERE of the “ Red Rectangle ” revisited
We present in this paper high signal-to-noise long-slit optical spectra of the Extended Red Emission (ERE) in the “Red Rectangle” (RR) nebula. These spectra, obtained at different positions in the nebula, reveal an extremely complex emission pattern on top of the broad ERE continuum. It is well known that three features converge at large distance from the central object, in wavelength and profi...
متن کاملObservational constraints on the ERE interpretation ⋆
Empirical relationships on the properties of the Extended Red Emission (ERE) are presented. They are based on published observational data and on new results obtained on reflection nebulae illuminated by cold stars. The plot of the width versus the central wavelength of the ERE band is in agreement with laboratory properties of the materials commonly proposed as the ERE carriers. But this is no...
متن کاملA Chandra/ACIS Study of 30 Doradus I. Superbubbles and Supernova Remnants
We present an X-ray tour of diffuse emission in the 30 Doradus star-forming complex in the Large Magellanic Cloud using high-spatial-resolution X-ray images and spatially-resolved spectra obtained with the Advanced CCD Imaging Spectrometer aboard the Chandra X-ray Observatory. The dominant X-ray feature of the 30 Doradus nebula is the intricate network of diffuse emission generated by interacti...
متن کاملDust Emission Features in NGC
We present 0.35 to 2.5 μm spectra of the south and northwest filaments in the reflection nebula NGC 7023. These spectra were used to test the theory of Seahra & Duley that carbon nanoparticles are responsible for Extended Red Emission (ERE). Our spectra fail to show their predicted second emission band at 1.0 μm even though both filaments exhibit strong emission in the familiar 0.7 μm ERE band....
