NOEMA maps the CO environment of the red supergiant Cep
M. Montargès, W. Homan, D. Keller +8
Red supergiant stars are surrounded by a gaseous and dusty circumstellar environment created by their mass loss which spreads heavy elements into the interstellar medium. The struc…
Developing a self-consistent AGB wind model: I. Chemical, thermal, and dynamical coupling
Jels Boulangier, Nicola Clementel, Allard Jan van Marle +2
The material lost through stellar winds of Asymptotic Giant Branch (AGB) stars is one of the main contributors to the chemical enrichment of galaxies. The general hypothesis of the…
The fossil wind structures of Eta Carinae: changes across on 5.54-year cycle
Theodore R. Gull, Thomas I. Madura, Mairan Teodoro +11
Eta Carinae, the closest, active, massive binary containing a highly unstable LBV, exhibits expanding, compressed wind shells, seen in emission, that are spatially and spectrally r…
To and beyond! The He I absorption variability across the 2014.6 periastron passage of Carinae
Noel D. Richardson, Thomas I. Madura, Lucas St-Jean +11
We have monitored the massive binary star Carinae with the CTIO/SMARTS 1.5~m telescope and CHIRON spectrograph from the previous apastron passage of the system through the rece…
3D radiative transfer simulations of Eta Carinae's inner colliding winds - II: Ionization structure of helium at periastron
Nicola Clementel, Thomas I. Madura, Chael J. H. Kruip +1
Spectral observations of the massive colliding wind binary Eta Carinae show phase-dependent variations, in intensity and velocity, of numerous helium emission and absorption lines…
3D Printing Meets Computational Astrophysics: Deciphering the Structure of Eta Carinae's Inner Colliding Winds
Thomas I. Madura, Nicola Clementel, Theodore R. Gull +2
We present the first 3D prints of output from a supercomputer simulation of a complex astrophysical system, the colliding stellar winds in the massive (>120 M_Sun), highly eccentri…
