NSCC -- A New Scheme of Classification of C-rich Stars Devised from Optical and Infrared Observations
Ana Beatriz de Mello, Silvia Lorenz-Martins, Francisco Xavier de Araújo +2
A new classification system for carbon-rich stars is presented based on an analysis of 51 AGB carbon stars through the most relevant classifying indices available. The extension in…
Spectroscopic analysis of two peculiar emission line stars: RJHA 49 and SS73 21
C. B. Pereira, W. L. F. Marcolino, M. Machado +1
Aims: To investigate the spectra and the evolutionary stages of two peculiar emission-line stars: RJHA 49 and SS73 21. Methods: We used low and high resolution optical data. Line i…
The spectroscopic orbits and other parameters of the symbiotic binary FN Sgr
E. Brandi, J. Mikolajewska, C. Quiroga +5
We present an analysis of optical and near infrared spectra of the eclipsing symbiotic system FN Sgr. In particular, we have determined for the first time spectroscopic orbits base…
