Discovery of sulfur oxides in the ejecta of a B[e] supergiant
C. Bordiu, J. Ricardo Rizzo, D. Navarro-Almaida +12
B[e] supergiants represent a rare class of luminous, evolved massive stars surrounded by dusty circumstellar disks. Since their intense UV fields were long thought to sterilize the…
Coherent and Incoherent Emission from the Ordered Magnetospheres of Low-Mass Stars, UCDs, and Massive Stars
Francesco Cavallaro, Paolo Leto, Barnali Das +15
Massive early-type (B/A) stars and ultracool dwarfs (UCDs) represent two distinct regimes in which ordered, large-scale magnetospheres are observed. In rapidly rotating massive sta…
The 10-15 GHz radio continuum survey of the Galactic Plane with SKAO
A. Traficante, C. Mininni, F. Cavallaro +63
Star formation emerges from the complex interplay between gravity, turbulence, magnetic fields, and stellar feedback, all of which vary across spatial scales and Galactic environme…
Supernova remnants in the new radio astronomy era
A. Ingallinera, M. Arias, G. Castelletti +25
Supernova remnants (SNRs) are what is left after stellar explosions, when the stellar ejecta, the explosion shock and the circumstellar medium interact. Despite being among the fir…
Evolved massive stars and their impact on their environment
C. S. Buemi, G. Umana, C. Trigilio +15
The comprehension of the final stages of massive star evolution and their path toward the eventual supernova explosion necessarily involves the study of stellar winds and the circu…
A scaling relationship for non-thermal radio emission from ordered magnetospheres - II. Investigating the efficiency of relativistic electron production in magnetospheres of BA-type stars
P. Leto, S. Owocki, C. Trigilio +19
Magnetic BA stars host dipole-like magnetospheres. When detected as radio sources, their luminosities correlate with the magnetic field and rotation. Rotation is crucial because th…
