New high resolution synthetic stellar libraries for the Gaia Mission
R. Sordo, A. Vallenari, J. C. Bouret +12
High resolution synthetic stellar libraries are of fundamental importance for the preparation of the Gaia Mission. We present new sets of spectral stellar libraries covering two sp…
Atmospheric dynamics of red supergiant stars and applications to Interferometry
A. Chiavassa, B. Plez, E. Josselin +1
We have written a 3D radiative transfer code that computes emerging spectra and intensity maps. We derive from radiative hydrodynamic (RHD) simulations of RSG stars carried out wit…
Atmospheric dynamics and the mass loss process in red supergiant stars
E. Josselin, B. Plez
Red supergiant stars represent a key phase in the evolution of massive stars. Recent radiative hydrodynamic simulations suggest that their atmospheres may be the location of large-…
The Reddening of Red Supergiants: When Smoke Gets In Your Eyes
Philip Massey, Bertrand Plez, Emily M. Levesque +3
Deriving the physical properties of red supergiants (RSGs) depends upon accurate corrections for reddening by dust. We use our recent modeling of the optical spectra of RSGs to add…
The Effective Temperature Scale of Galactic Red Supergiants: Cool, But Not As Cool As We Thought
Emily M. Levesque, Philip Massey, K. A. G. Olsen +4
We use moderate-resolution optical spectrophotometry and the new MARCS stellar atmosphere models to determine the effective temperatures of 74 Galactic red supergiants. From these…
The chemistry of compact planetary nebulae
E. Josselin, R. Bachiller
We report high-sensitivity millimetre observations of several molecular species (13CO, HCN, HNC, CN, HCO+ and N2H+) in a sample of compact planetary nebulae. Some species such as H…
