HD 93795: a late-B supergiant star with a square circumstellar nebula
V. V. Gvaramadze, A. Y. Kniazev, N. Castro +1
We report the discovery of a square axisymmetric circumstellar nebula around the emission-line star HD 93795 in archival Spitzer Space Telescope 24 micron data. We classify HD 9379…
Resolving stellar populations with integral field spectroscopy
Martin M. Roth, Peter M. Weilbacher, Norberto Castro
High-performance instruments at large ground-based telescopes have made integral field spectroscopy (IFS) a powerful tool for the study of extended objects such as galaxies, nebula…
Properties of OB star-black hole systems derived from detailed binary evolution models
N. Langer, C. Schürmann, K. Stoll +38
The recent gravitational wave measurements have demonstrated the existence of stellar mass black hole binaries. It is essential for our understanding of massive star evolution to i…
No evidence of a sudden change of spectral appearance or magnetic field strength of the O9.7V star HD 54879
G. A. Wade, S. Bagnulo, Z. Keszthelyi +8
It was recently claimed that the magnetic O-type star HD 54879 exhibits important radial velocity variability indicative of its presence in a spectroscopic binary. More remarkably,…
Massive stars in extremely metal-poor galaxies: A window into the past
M. Garcia, C. J. Evans, J. M. Bestenlehner +19
Cosmic History has witnessed the lives and deaths of multiple generations of massive stars, all of them invigorating their host galaxies with ionizing photons, kinetic energy, fres…
BlueMUSE: Project Overview and Science Cases
Johan Richard, Roland Bacon, Jérémy Blaizot +59
We present the concept of BlueMUSE, a blue-optimised, medium spectral resolution, panoramic integral field spectrograph based on the MUSE concept and proposed for the Very Large Te…
