The VLT-FLAMES Tarantula Survey XXV. Surface nitrogen abundances of O-type giants and supergiants
N. J. Grin, O. H. Ramirez-Agudelo, A. de Koter +19
Theoretically, rotation-induced chemical mixing in massive stars has far reaching evolutionary consequences, affecting the sequence of morphological phases, lifetimes, nucleosynthe…
Spectral classification and properties of the O Vz stars in the Galactic O-Star Spectroscopic Survey (GOSSS)
Julia I. Arias, Nolan R. Walborn, Sergio Simon-Diaz +11
On the basis of the Galactic O-Star Spectroscopic Survey (GOSSS), a detailed systematic investigation of the O Vz stars is presented. The currently used spectral classification cri…
The R136 star cluster dissected with Hubble Space Telescope/STIS. I. Far-ultraviolet spectroscopic census and the origin of HeII 1640 in young star clusters
Paul A. Crowther, S. M. Caballero-Nieves, K. A. Bostroem +17
We introduce a HST/STIS stellar census of R136a, the central ionizing star cluster of 30 Doradus. We present low resolution far-ultraviolet STIS/MAMA spectroscopy of R136 using 17…
New Luminous ON Spectra from the Galactic O-Star Spectroscopic Survey
Nolan R. Walborn, Nidia I. Morrell, Rodolfo H. Barba +1
Two new ON supergiant spectra (bringing the total known to seven) and one new ONn giant (total of this class now eight) are presented; they have been discovered by the Galactic O-S…
The Galactic O-Star Spectroscopic Survey (GOSSS). III. 142 additional O-type systems
J. Maíz Apellániz, A. Sota, J. I. Arias +9
This is the third installment of GOSSS, a massive spectroscopic survey of Galactic O stars, based on new homogeneous, high signal-to-noise ratio, R~2500 digital observations select…
