Non-thermal emission in hyper-velocity and semi-relativistic stars
J. R. Martinez, S. del Palacio, V. Bosch-Ramon +1
Context. There is a population of runaway stars that move at extremely high speeds with respect to their surroundings. The fast motion and the stellar wind of these stars, plus the…
New insights in the HII region G18.88-0.49: hub-filament system and accreting filaments
L. K. Dewangan, D. K. Ojha, Saurabh Sharma +3
We present an analysis of multi-wavelength observations of an area of 0.27 deg x 0.27 deg around the Galactic HII region G18.88-0.49, which is powered by an O-type star (age ~10^5…
Bow-shocks, nova shells, disc winds and tilted discs: The Nova-Like V341 Ara Has It All
N. Castro Segura, C. Knigge, J. A. Acosta-Pulido +21
V341 Ara was recently recognised as one of the closest (d ~ 150 pc) and brightest (V~ 10) nova-like cataclysmic variables. This unique system is surrounded by a bright emission neb…
Probing the physical conditions and star formation processes in the Galactic HII region S305
L. K. Dewangan, Saurabh Sharma, Rakesh Pandey +5
We present multi-scale and multi-wavelength observations of the Galactic HII region S305, which is excited by massive O8.5V and O9.5V stars. Infrared images reveal an extended sphe…
The high-energy emission from HD~93129A near periastron
S. del Palacio, F. García, D. Altamirano +12
We conducted an observational campaign towards one of the most massive and luminous colliding wind binaries in the Galaxy, HD~93129A, close to its periastron passage in 2018. Durin…
A model for the non-thermal emission of the very massive colliding-wind binary HD 93129A
Santiago del Palacio, Valentí Bosch-Ramon, Gustavo E. Romero +1
The binary stellar system HD 93129A is one of the most massive known binaries in our Galaxy. This system presents non-thermal emission in the radio band, which can be used to infer…
