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…
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…
Evolutionary Map of the Universe: Detection and Analysis of the Shell Surrounding the Runaway Wolf-Rayet Star WR16
A. C. Bradley, M. D. Filipović, Z. J. Smeaton +18
We present the first radio--continuum detection of the circumstellar shell around the well-known WN8 type Wolf-Rayet star WR16 at 943.5\,MHz using the \ac{ASKAP} \ac{EMU} survey. A…
The distance to CRL 618 through its radio expansion parallax
L. Cerrigone, G. Umana, C. Trigilio +9
CRL 618 is a post-AGB star that has started to ionize its ejecta. Its central HII region has been observed over the last 40 years and has steadily increased in flux density at radi…
The rich molecular environment of the luminous blue variable star AFGL 2298
J. R. Rizzo, C. Bordiu, C. Buemi +6
We investigated the molecular environment of AFGL 2298, an obscured Galactic Luminous blue variable (LBV) star which hosts a highly structured circumstellar environment with hints…
Discovery and origin of the radio emission from the multiple stellar system KQVel
P. Leto, L. M. Oskinova, C. S. Buemi +20
KQVel is a binary system composed of a slowly rotating magnetic Ap star with a companion of unknown nature. In this paper, we report the detection of its radio emission. We conduct…
A scaling relationship for non-thermal radio emission from ordered magnetospheres: from the top of the Main Sequence to planets
P. Leto, C. Trigilio, J. Krticka +20
In this paper, we present the analysis of incoherent non-thermal radio emission from a sample of hot magnetic stars, ranging from early-B to early-A spectral type. Spanning a wide…
