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…
The FLAMES Tarantula Survey
N. Markova, C. Evans, N. Bastian +30
The Tarantula survey is an ESO Large Programme which has obtained multi-epochs spectroscopy of over 800 massive stars in the 30 Dor region in the Large Magelanic Cloud. Here we bri…
Discovery of the massive overcontact binary VFTS 352: Evidence for enhanced internal mixing
L. A. Almeida, H. Sana, S. E. de Mink +15
The contact phase expected to precede the coalescence of two massive stars is poorly characterized due to the paucity of observational constraints. Here we report on the discovery…
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…
A dearth of young and bright massive stars in the Small Magellanic Cloud
A. Schootemeijer, N. Langer, D. Lennon +7
Massive star evolution at low metallicity is closely connected to many fields in high-redshift astrophysics, but poorly understood. The Small Magellanic Cloud (SMC) is a unique lab…
Surface abundances of OC supergiants
F. Martins, S. Foschino, J. -C. Bouret +2
Some O and B stars show unusually strong or weak lines of carbon and/or nitrogen. These objects are classified as OBN or OBC stars. It has recently been shown that nitrogen enrichm…
