We present mid-infrared (10.4 μm, 11.7 μm, and 18.3 μm) imaging intended to locate and characterize the suspected protostellar components within the Bok globule CB54. We detect and confirm the protostellar status for the near-infrared source CB54YC1-II. The mid-infrared luminosity for CB54YC1-II was found to be Lmidir ≈ 8 L⊙, and we estimate a central source mass of M∗ ≈ 0.8 M⊙ (for a mass accr...

Oxygen plasma effects on optical properties of ZnSe films" (2002). Zinc selenide is an infrared transparent semiconductor material being considered for use in space as an infrared optical coating. In this work, zinc selenide thin films of different thicknesses were exposed to an electron cyclotron resonance generated oxygen plasma, often used to ''simulate'' the low earth orbital environment. T...

Near-infrared photometry at /, H, and K has been obtained for 82 galaxies from the IRAS minisurvey, a sample of infrared-selected galaxies. The near-infrared colors of these galaxies are similar to those of normal field spiral galaxies, but cover a larger range inJ — H and H — K. There is evidence of a tighter correlation between the nearand far-infrared emission than exists between the far-inf...

JCT CoatingsTech In this JCT COATINGSTECH series of introductory tutorial articles, the emphasis sought is on the applications of modern analytical, characterization, and testing methods for coatings. And while it is easy to cite many examples of recent applications of mid-infrared spectroscopy, the most common sampling techniques employed have been well established for a long time and, as a co...
