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…
