2. New Infrared Emission Features and Spectral Variations in NGC 7023
We observed the reflection nebula NGC 7023, with the Short-High module and the long-slit Short-Low and Long-Low modules of the Infrared Spectrograph on the Spitzer Space Telescope. We also present Infrared Array Camera (IRAC) and Multiband Imaging Photometer for Spitzer (MIPS) images of NGC 7023 at 3.6, 4.5, 8.0, and 24 ЮМm. We observe the aromatic emission features (AEFs) at 6.2, 7.7, 8.6, 11.3, and 12.7 ЮМm, plus a wealth of weaker features. ... ADS Citation Query . citations = 112 . ...

6. Summary and conclusions
... We carried out follow-up spectroscopy of 178 Case galaxies in the zone - 16 h , and - +38 ,classified in the Case catalog with some code, indicating the presence of the line [O III ] 5007, and not observed in the previous follow-up studies. ... We conclude that Case ELGs give the high fraction of BCGs -- about 60 % of all galaxies with strong enough emission lines, and more than 40 % of all Case galaxies, marked with some code of the presence of [O III ] line. ...

8. http://star.arm.ac.uk/~ambn/abstract328.html
We model the spectral chanages of late oxygen-rich Miras observed in different pulsation phases. From a combination of variable near-IR spectra and UKIRT spectrophotometry of the 9.7 \mu m silicate dust emission feature in different phases we study the influence of the changing atmospherical circumstances on the conditions in the circumstellar dust shell. ... A comparision with the modelling results for another long period Mira U Ori is also provided. ...

12. Programme - Abstract
... Programme . ... Abstract: Planetary nebulae constitute a unique source of light element abundances for individual stars in a distant stellar population. Multi-slit spectra of 50 planetary nebulae (PN) in NGC 5128 have been observed with the ESO VLT and FORS1 spectrometer. The planetary nebulae were observed in three fields covering a range of galactic radii from 2 to 19 kpc. The emission line spectra have been analysed for light element abundances (He, O, N, Ne, S, Ar). ...
