Next: Functionality Up: RGS_EXAFS Previous: RGS_EXAFS Contents . EXAFS means Extended X-ray Absorption Fine Structure. This CCF describes the detailed absorption lengths of different layers of CCDs in the vicinity of absoption edges to facilitate accurate calculation of quantum efficiencies. Away from the edges, the well-known Henke coefficients are used. There are two notable RGS instrumental absorption features by oxygen and fluorine. ... Michael Smith 2011-09-20 ...

... The larger image shows the entire nebula; the inset picture captures the complicated structure surrounding the dying star. The remarkable features of this nebula are the numerous holes in the inner shells with jets of material streaming from them. ... The multiple shells of material ejected by the dying star give this planetary nebula its odd form. ... At least four jets of material can be seen in the "full nebula" image: a pair near 6 and 12 o'clock and another near 2 and 8 o'clock. ...

Comment on J0513-2159 . Our image shows an extension to about 5 mas SE from the brightest feature. The EVN 8 GHz image by Dallacasa et al. (1998), with about five times larger resolution, shows an extension from the brightest feature roughly opposite to our direction. As noted by Dallacasa et al. (1998), the structure detected has a highly inverted spectrum, which, together with the reported variability in the source, could explain the structural disagreement. ...

... arXiv.org . ... Although great progress has been made in modelling the disk with radiative transfer models able to reproduce the spectral energy distribution (SED) of Herbig Ae stars, the constraints brought by images have not been yet fully exploited. Here, we are interested in checking if these new observational imaging constraints can be accounted for by predictions based on existing models of passive centrally irradiated hydrostatic disks made to fit the SEDs of the Herbig Ae stars. ...
