Synthetic photometry of globular clusters: Uncertainties on synthetic colors
F. Martins
Synthetic photometry is a great tool for studying globular clusters, especially for understanding the nature of their multiple populations. Our goal is to quantify the errors on sy…
A study of the effect of rotational mixing on massive stars evolution: surface abundances of Galactic O7-8 giant stars
F. Martins, S. Simon-Diaz, R. H. Barba +2
Massive star evolution remains only partly constrained. In particular, the exact role of rotation has been questioned by puzzling properties of OB stars in the Magellanic Clouds. O…
Observational signatures of past mass-exchange episodes in massive binaries: The case of HD 149 404
F. Raucq, G. Rauw, E. Gosset +4
Mass and momentum exchanges in close massive binaries play an important role in their evolution, and produce several observational signatures such as asynchronous rotation and alte…
Properties of massive stars in four clusters of the VVV survey
A. Hervé, F. Martins, A. -N. Chené +2
The evolution of massive stars is only partly understood. Observational constraints can be obtained from the study of massive stars located in young massive clusters. The ESO Publi…
Surface abundances of ON stars
F. Martins, S. Simon-Diaz, A. Palacios +5
Massive stars burn hydrogen through the CNO cycle during most of their evolution. When mixing is efficient, or when mass transfer in binary systems happens, chemically processed ma…
The MiMeS Survey of Magnetism in Massive Stars: CNO surface abundances of Galactic O stars
F. Martins, A. Hervé, J. -C. Bouret +7
The evolution of massive stars is still partly unconstrained. Mass, metallicity, mass loss and rotation are the main drivers of stellar evolution. Binarity and magnetic field may a…
Rotation, spectral variability, magnetic geometry and magnetosphere of the Of?p star CPD -28 2561
G. A. Wade, R. H. Barbá, J. Grunhut +14
We report magnetic and spectroscopic observations and modeling of the Of?p star CPD -28 2561. Using more than 75 new spectra, we have measured the equivalent width variations and e…
Radial dependence of line profile variability in seven O9--B0.5 stars
F. Martins, W. Marcolino, D. J. Hillier +2
Massive stars show a variety of spectral variability: presence of discrete absorption components in UV P-Cygni profiles, optical line profile variability, X-ray variability, radial…
A comparison of evolutionary tracks for single Galactic massive stars
F. Martins, A. Palacios
In this paper, we compare the currently available evolutionary tracks for Galactic massive stars. Our main goal is to highlight the uncertainties on the predicted evolutionary path…
Discovery of a magnetic field in the rapidly-rotating O-type secondary of the colliding-wind binary HD 47129 (Plaskett's star)
J. H. Grunhut, G. A. Wade, M. Leutenegger +14
We report the detection of a strong, organized magnetic field in the secondary component of the massive O8III/I+O7.5V/III double-lined spectroscopic binary system HD 47129 (Plasket…
Near-Infrared spectroscopy of the super star cluster in NGC1705
F. Martins, N. M. Foerster Schreiber, F. Eisenhauer +1
We study the near-infrared properties of the super star cluster NGC1750-1 in order to constrain its spatial extent, its stellar population and its age. We use adaptive optics assis…
On the formation of CIII 4647-50-51 and CIII 5696 in O star atmospheres
F. Martins, D. J. Hillier
We investigate the formation of CIII 4647-51-50 and CIII 5696 in the atmosphere of O stars to see if they can be reliably used for abundance determinations. We use atmosphere model…
NGC 1624-2: A slowly rotating, X-ray luminous Of?cp star with an extraordinarily strong magnetic field
G. A. Wade, J. Maíz Apellániz, F. Martins +16
This paper presents a first observational investigation of the faint Of?cp star NGC 1624-2, yielding important new constraints on its spectral and physical characteristics, rotatio…
A quantitative study of O stars in NGC2244 and the Mon OB2 association
F. Martins, L. Mahy, G. Rauw +1
Our goal is to determine the stellar and wind properties of seven O stars in the cluster NGC2244 and three O stars in the OB association MonOB2. These properties give us insight in…
The spectral variability and magnetic field characteristics of the Of?p star HD 148937
G. A. Wade, J. Grunhut, G. Graefener +11
We report magnetic and spectroscopic observations and modeling of the Of?p star HD 148937 within the context of the MiMeS LP at the CFHT. Thirty-two high signal-to-noise ratio circ…
Of?p stars: a class of slowly rotating magnetic massive stars
G. A. Wade, J. H. Grunhut, W. L. F. Marcolino +5
Only 5 Of?p stars have been identified in the Galaxy. Of these, 3 have been studied in detail, and within the past 5 years magnetic fields have been detected in each of them. The o…
