Dust and Diffuse Interstellar Bands in the z_a = 0.524 Absorption System toward AO 0235+164
V. T. Junkkarinen, Ross D. Cohen, E. A. Beaver +3
We present new HST STIS NUV-MAMA and STIS CCD observations of the BL Lac object AO 0235+164 and the intervening damped Ly alpha (DLA) line at z_a = 0.524. The line profile gives N(…
Discovery of a 2 Kpc Binary Quasar
G. A. Shields, V. Junkkarinen, E. A. Beaver +4
LBQS 01032753 is a binary quasar with a separation of only 0.3 arcsec. The projected spacing of 2.3 kpc at the distance of the source (z = 0.848) is much smaller than that of an…
AB Dor in '94: I. HST/GHRS Observations of the Quiescent Chromosphere of an Active Star
J. C. Brandt, S. R. Heap, F. M. Walter +15
We analyze HST/GHRS spectra of AB Doradus, the prototypical ultra-rapidly rotating K dwarf. We observed chromospheric (Mg II) and transition region (C II, Si IV, C IV, and N V) lin…
The Nature and Origin of z_a~z_e Absorption Lines in the Redshift 0.20 Quasar, PKS 2135-147
Fred Hamann, E. A. Beaver, Ross D. Cohen +3
We use new UV and optical spectra and an archival HST-WFPC2 image to study the z_a~z_e absorber in the z_e = 0.20 QSO PKS 2135-147. The UV spectra, obtained with HST-FOS, show stro…
