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…
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…
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…
Exploring the multifaceted circumstellar environment of the Luminous Blue Variable HR Carinae
C. S. Buemi, C. Trigilio, P. Leto +9
We present a multi-wavelength study of the Galactic Luminous Blue Variable HR Carinae, based on new high resolution mid-infrared (IR) and radio images obtained with the Very Large…
