Non-thermal radio emission from O-type stars. IV. Cyg OB2 No. 8A
R. Blomme, M. De Becker, D. Volpi +1
We study the non-thermal radio emission of the binary Cyg OB2 No. 8A, to see if it is variable and if that variability is locked to the orbital phase. We investigate if the synchro…
The colliding-wind binary HD 168112
R. Blomme, G. Rauw, D. Volpi +2
Radio surveys of early-type stars have revealed a number of non-thermal emitters. Most of these have been shown to be binaries, where the collision between the two stellar winds is…
MELCHIORS: The Mercator Library of High Resolution Stellar Spectroscopy
P. Royer, T. Merle, K. Dsilva +71
Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a given object or a given spec…
Polarization in Pulsar Wind Nebulae
D. Volpi, L. Del Zanna, E. Amato +1
The main goal of our present work is to provide, for the first time, a simple computational tool that can be used to compute the brightness, the spectral index, the polarization, t…
The Gaia-ESO Survey: The analysis of the hot-star spectra
R. Blomme, S. Daflon, M. Gebran +44
The Gaia-ESO Survey (GES) is a large public spectroscopic survey that has collected, over a period of 6 years, spectra of ~ 10^5 stars. This survey provides not only the reduced sp…
Non-thermal radio emission from O-type stars. V. 9 Sgr
R. Blomme, D. Volpi
The colliding winds in a massive binary system generate synchrotron emission due to a fraction of electrons that have been accelerated to relativistic speeds around the shocks in t…
