There is often dust associated with ionized regions. Compact HII regions usually have associated dust from a molecular cloud in which the massive star is being "born". ... For such stars the dust is not produced by the star, and a variety of dust features are observed. The planetary nebulae also usually have associated dust from the previous stage of evolution where they were either carbon stars or M-type giants. ... The feature near 11.5 microns in the IC 418 spectrum may be due to SiC dust. ...

Deep imaging at J , H , and K is required to identify all stellar objects, brown dwarfs, and planetary mass objects in the central region of the Orion Nebula Cluster down to masses comparable to that of Jupiter. This is required to establish the initial mass function, i.e., the number of stars of each mass that have formed, in this region of intense massive star formation. ...

... Astronomers often talk about stars being huge balls of gas, but they contain a lot of dust too. Take a look at this striking new picture of a region in space in which new stars are being born, called the Carina Nebula. ... However, massive stars that are found in the Nebula can help to push more gas and dust particles together. Such massive stars give off strong winds that can blow material together like when leaves or litter gather together in the playground on a windy day. ...

Most current theories for magnetospheric emission can be grouped into polar cap, outer gap, and nebular models. These models, at least in some cases, need not be mutually exclusive; the Crab pulsar (among others), for example, shows clear evidence for pulsed emission from the magnetosphere and unpulsed emission from the surrounding nebula. ... This suggestion is strengthened by observation of a distinct soft emission component, consistent with the cooling scenario, from several of these pulsars. ...

... Dust in the region is studied photometrically at ultraviolet, optical, and far-infrared wavelengths to analyze nebular colors, grain properties, and scattering geometry. Constraints on this geometry are provided by spectroscopy of radio emission lines and optical absorption lines of the interstellar gas, which also reveal a significant amount of fine-scale filamentary structure. ...
