Pox 186: an ultracompact galaxy with dominant ionized gas emission
N. G. Guseva, P. Papaderos, Y. I. Izotov +2
We present a ground-based optical spectroscopic and HST U, V, I photometric study of the blue compact dwarf (BCD) galaxy Pox 186. It is found that the emission of the low-surface b…

Deep VLT spectroscopy of the blue compact dwarf galaxies Tol 1214-277 and Tol 65
Y. I. Izotov, P. Papaderos, N. G. Guseva +2
We present VLT spectroscopic observations with different spectral resolutions and different slit orientations of the two metal-deficient blue compact dwarf (BCD) galaxies Tol 1214-…

Time-resolved photometry and spectroscopy of the new deeply-eclipsing SW Sextantis star HS 0728+6738
P. Rodriguez-Gil, B. T. Gaensicke, H. Barwig +2
We present time-resolved optical spectroscopy and photometry, and far-ultraviolet spectroscopy of HS 0728+6738, a cataclysmic variable discovered in the Hamburg Quasar Survey. We s…
