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…
Correlation between active regions' spectra at high radio frequencies and solar flare occurrences
Sara Mulas, Alberto Pellizzoni, Marco Marongiu +31
High radio frequencies observations with the Italian network of large single-dish radio telescopes resulted in ~450 solar images between 2018 and 2023 in K-band frequency range (18…
