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…
The Ultraviolet Spectra of the Weak Emission Line Central Stars of Planetary Nebulae
W. L. F. Marcolino, F. X. de Araujo, H. B. M. Junior +1
The ultraviolet spectra of all ``weak emission line central stars of planetary nebulae'' (WELS) with available IUE data are presented and discussed. We performed line identificatio…
The Projected Rotational Velocity Distribution of a Sample of OB stars from a Calibration based on Synthetic He I lines
S. Daflon, K. Cunha, F. X. de Araujo +2
We derive projected rotational velocities (vsini) for a sample of 156 Galactic OB star members of 35 clusters, HII regions, and associations. The HeI lines at 4026, 4388, and 4…
