Hαspectropolarimetry of RY Tau and PX Vul
A. Pereyra, A. M. Magalhães, F. X. de Araújo
Aims: To detect line effects using spectropolarimetry in order to find evidence of rotating disks and their respective symmetry axes in T Tauri stars. Methods: We used the IAGPOL i…
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…
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…
Detailed Far-UV to Optical Analysis of Four [WR] Stars
W. L. F. Marcolino, D. J. Hillier, F. X. de Araujo +1
We present far-UV to optical analyses of four hydrogen deficient central stars of planetary nebulae: BD+303639, NGC 40, NGC 5315 and NGC 6905. Using the radiative transfer code CMF…
