Next: Analysis Tools for Nebular Emission Lines . ... Extracting spectra from a large number of NICMOS grism images requires a convenient interactive tool which allows a user to manipulate direct/grism image pairs. ... The direct image is used to locate objects of interest, to find the position of the appropriate spectra in the grism image, to determine the optimal extraction technique to use, and to calibrate the wavelength range of the extracted spectra. ...

Next: Boron in the Up: The Interstellar Medium Previous: GHRS Observations of . ... The Goddard High Resolution Spectrograph (GHRS) of the Hubble Space Telescope (HST) has been used to obtain a spectrum of the boron 2500? region of BD-13^o 3442. ... We used the line list of Duncan et al. (1996a), which consists almost entirely of laboratory-measured lines, and which fits both the Hyades giants and metal-poor stars. ... It is clear that BD-13^o 3442 is the most metal-poor star of the three. ...

... HD144941 is a B type hydrogen-deficient star. ... However, its H/He ratio puts it between the classifications of an extreme and an intermediate helium star, and its low C and N abundances make it unique amongst known H-deficient stars. ... Keywords. stars: helium stars -- stars: individual stars (HD144941) -- stars: atmospheres -- stars: abundances -- stars: oscillations -- stars: evolution . ... The iron abundance in the helium star HD144941 has been measured from ultraviolet Fe III lines. ...

... Comparative study of Tl-2201 single crystals with T c =30 and 110 K by means of X-ray structural analysis and NMR. Abstract: . The crystal structure of a tetragonal single crystal of Tl-2201 with T c =30 K has been determined by the X-ray diffraction technique ( a = 3.8717(3), c = 23.224(3) Angstrom, space group I4/mmm, Z = 2). The chemical composition is found to be Tl 1.90(1) Cu 0.10(1) Ba 2 CuO 6.18(4) . ... Structural parameters of Tl-2201 cuprates with various T c have been compared. ...

... A correlation between metal abundance and orbital elements (the eccentricity and angular momentum) has been found for three semples of disk stars of our Galaxy with abundance derived from detailed analysis. The correlation indicates that metal abundance in the Galaxy kept increasing after the birth of old disk stars and that the Galaxy kept collapsing during the formation of its disk subsystems. ...
