On the nature of V 589 Sagittarii

Mennickent, RE; Greiner, J; Tovmassian, G (2001)

We present optical and near infrared spectroscopy of the symbiotic star candidate V589 Sgr. The presence of TiO and VO absorption bands, along with strong H I and He I emissions, confirm the symbiotic star classification, ...
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 ...
