Spitzer Space Telescope mid-infrared spectroscopy has been obtained for 15 carbon-rich protoplanetary nebulae (PPNe) in the Large Magellanic Cloud (LMC) and for two other such stars in the Small Magellanic Cloud (SMC). Of these 17 PPNe, the unidentified 21 ѕ®m feature is strong in 7 spectra, weak in 2 spectra, and very weak or questionable in 4 spectra. ... The remaining two objects show typical carbon-rich PPNe spectra with no 21 ѕ®m features. ...

Next: Coordinate Systems Up: IRAF/PROS Previous: Other Types of Files . A few new features and enhancements to the standard IRAF system have been introduced with the PROS software: . ... Default compound extensions are used by the PROS tasks when no extension is given for the output file name. Most PROS tasks allow the output file name to be defaulted, with the convention that the output file name will be composed of the input `root' name, plus the default extension specific to the task. ...

... A new IRAF task has been developed that automatically identifies linear (line-like) features in an image or set of images. ... In order to automatically detect linear features, the first step is to select pixels in the image (Fig. 1 , left panel) that fall within a given data value range. ... Another aspect of extended linear features is that the image space pixels that describe them are in some way adjacent to one another and have a minimum and maximum length. ...

... Laboratory and theoretical modelling of the UV bump on the interstellar extinction curve is a very popular topic in dusty investigations. ... feature is illustrated by Fig. 10 where the profiles were calculated using the model of graphite spheres. Figure 10: Normalized extinction efficiencies for graphite spheres. ... The lower panel shows the summary extinction of two graphite spheres with radii and (from upper panel) taken in equal proportions. ...

... If finddead =Y, embadpixfind looks for too dark pixels, rows and columns too. ... The maxratio parameter avoids detecting 'grey' pixels, rows or columns on observations with high statistics. Whatever findbright and finddead , dark and bright columns and rows are always searched for together in order of decreasing significance (either positive or negative). This avoids finding spurious bright columns/rows next to very dark ones, and vice-versa. ...

Sequence of four video frames captured at 01:05 BST at Armagh Observatory on the night of the 24/25th July 2013, showing the onset, development and demise of the sprite. ... Unlike common lightning discharges, which often jump between clouds or between the clouds and the ground, sprites are associated with similarly powerful electrical fields that occur high above the clouds of the EarthтАЩs atmosphere. ...

. This collage, consisting of two Cassini images of long, sinuous, tendril-like features from Saturn's moon Enceladus (grainy images) and two corresponding computer simulations of the same features (clearer images), illustrates how well the structures, and the sizes of the particles composing them, can be modeled by tracing the trajectories of tiny, icy grains ejected from Enceladus' south polar geysers.
