Variation of the Diameter of the Sun as Measured by the Solar Disk Sextant (SDS)
S. Sofia, T. M. Girard, U. J. Sofia +3
The balloon-borne Solar Disk Sextant (SDS) experiment has measured the angular size of the Sun on seven occasions spanning the years 1992 to 2011. The solar half-diameter -- observ…
Estimation of C II and C II* column densities along Galactic sight-lines
Veena S. Parvathi, Ulysses J. Sofia, Jayant Murthy +1
We present interstellar C II (1334.5323 Å) and C II* (1335.7077 Å) column density measurements along 14 Galactic sight-lines. These sight-lines sample a variety of Galactic disk en…
Interstellar Krypton Abundances: The Detection of Kiloparsec-scale Differences in Galactic Nucleosynthetic History
Stefan I. B. Cartledge, J. T. Lauroesch, David M. Meyer +2
We present an analysis of Kr I 1236 line measurements from 50 sight lines in the Hubble Space Telescope Space Telescope Imaging Spectrograph and Goddard High Resolution Spectrograp…
Interstellar Iron and Silicon Depletions in Translucent Sight Lines
Adam Miller, J. T. Lauroesch, Ulysses J. Sofia +2
We report interstellar FeII and SiII column densities toward six translucent sight lines (A_V >~ 1) observed with the Space Telescope Imaging Spectrograph (STIS). The abundances we…
The Homogeneity of Interstellar Elemental Abundances in the Galactic Disk
Stefan I. B. Cartledge, J. T. Lauroesch, David M. Meyer +1
We present interstellar elemental abundance measurements derived from Space Telescope Imaging Spectrograph echelle observations of 47 sight lines extending up to 6.5 kpc through th…
FUSE Measurements of Far Ultraviolet Extinction. II. Magellanic Cloud Sight Lines
Stefan I. B. Cartledge, Geoffrey C. Clayton, Karl D. Gordon +8
We present an extinction analysis of 9 paths through the LMC and SMC based on FUSE observations. To date, just two LMC sight lines have probed dust grain composition and size distr…
