  • Hubble Space Telescope observations of the luminous blue variable/W-R eclipsing binary system HD 5980
    Koenigsberger, G; Georgiev, L; Barba, R; Tzvetanov, Z; Walborn, NR; Niemela, VS; Morrell, N; Schulte-Ladbeck, R (2000)
    We report the results of Hubble Space Telescope STIS observations of the intriguing luminous blue variable/Wolf-Rayet binary system HD 5980 in the Small Magellanic Cloud. Although its spectral characteristics (WN6) are ...
  • On the secondary star of the cataclysmic variable 1RXS J094432.1+035738
    Mennickent, RE; Tovmassian, G; Zharikov, SV; Tappert, C; Greiner, J; Gansicke, BT; Fried, RE (2002)
    We present V and R-c-band photometry and optical near-infrared spectroscopy of the cataclysmic variable 1RXS J094432.1+035738. We detected features of a cool secondary star, which can be modeled with a red dwarf of spectral ...
  • The remarkable properties of the symbiotic star AE Circinus
    Mennickent, R; Greiner, J; Arenas, J; Tovmassian, G; Mason, E; Tappert, C; Papadaki, C (2008)
    We present new optical spectroscopy and photometry, Two-Micron All-Sky Survey (2MASS) infrared observations and 24 yr of combined American Association of Variable Star Observers (AAVSO) and Association Francaise des ...
