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…
Millimetre continuum from LBV stars and their environs. NIKA2 observations and Virtual Observatory data
J. R. Rizzo, C. Bordiu, A. Ritacco
Multi-wavelength studies of their circumstellar environments around LBVs are essential to quantify their feedback at Galactic scales. Dominant emission mechanisms at millimetre wav…
NIKA2 observations around LBV stars: emission from stars and circumstellar material
J. Ricardo Rizzo, A. Ritacco, C. Bordiu
Luminous Blue Variable (LBV) stars are evolved massive objects, previous to core-collapse supernova. LBVs are characterized by photometric and spectroscopic variability, produced b…
The peculiar chemistry of the inner ejecta of Eta Carina
C. Bordiu, J. R. Rizzo
We investigated continuum and molecular line emission of four species (CO, HCN, HCN, and HCO) at 0.8 mm in the inner arcsec around Eta Car, using ALMA archival observati…
A slowly expanding torus associated with the candidate LBV MGE 042.0787+00.5084
C. Bordiu, J. R. Rizzo, A. Ritacco
The luminous blue variable (LBV) phase is a poorly understood stage in the evolution of high mass stars, characterized for its brevity and instability. The surroundings of LBV star…
