Discovery of the first symbiotic star in NGC6822
A. Kniazev, P. Vaisanen, P. A. Whitelock +10
We report the discovery of the first symbiotic star (V=21.6, K_S=15.8 mag) in the Local Group dwarf irregular galaxy NGC6822. This star was identified during a spectral survey of H…
Recombination Ghosts in Littrow Configuration: Implications for Spectrographs Using Volume Phase Holographic Gratings
Eric B. Burgh, Matthew A. Bershady, Kyle B. Westfall +1
We report the discovery of optical ghosts generated when using Volume Phase Holographic (VPH) gratings in spectrographs employing the Littrow configuration. The ghost is caused by…
The metallicity extremes of the Sagittarius dSph using SALT spectroscopy of PNe
A. Kniazev, A. Zijlstra, E. Grebel +10
In this work we present the first spectroscopic results obtained with the Southern African Large Telescope (SALT) telescope during its perfomance-verification phase. We find that t…
The polar ring galaxy AM1934-563 revisited
N. Brosch, A. Kniazev, D. Buckley +8
We report long-slit spectroscopic observations of the dust-lane polar-ring galaxy AM1934-563 obtained with the Southern African Large Telescope (SALT) during its performance-verifi…
SDSS J160043.6+074802.9: a very rapid sdO pulsator
P. A. Woudt, D. Kilkenny, E. Zietsman +12
We report the serendipitous discovery of the Sloan Digital Sky Survey star, SDSS J160043.6+074802.9 to be a very rapid pulsator. The variation is dominated by a frequency near 8380…
Rocket and FUSE Observations of IC 405: Differential Extinction and Fluorescent Molecular Hydrogen
K. France, S. R. McCandliss, E. B. Burgh +1
We present far-ultraviolet spectroscopy of the emission/reflection nebula IC 405 obtained by a rocket-borne long-slit spectrograph and the Far Ultraviolet Spectroscopic Explorer. B…
