Horizontal Branch stars as AmFm/HgMn stars
G. Michaud, J. Richer
Recent observations and models for horizontal branch stars are briefly described and compared to models for AmFm stars. The limitations of those models are emphasized by a comparis…
Radiative Accelerations in Stellar Evolution
G. Michaud, J. Richer
A brief review of various methods to calculate radiative accelerations for stellar evolution and an analysis of their limitations are followed by applications to Pop I and Pop II s…
Implications of WMAP observations on Li abundance and stellar evolution models
Olivier Richard, Georges Michaud, Jacques Richer
The WMAP determination of the baryon-to-photon ratio implies, through Big Bang nucleosynthesis, a cosmological Li abundance larger, by a factor of 2 to 3, than the Li abundance pla…
Models for Solar Abundance Stars with Gravitational Settling and Radiative Accelerations: Application to M67 and NGC188
G. Michaud, O. Richard, J. Richer +1
Evolutionary models taking into account radiative accelerations, thermal diffusion, and gravitational settling for 28 elements, including all those contributing to OPAL stellar opa…
Dust properties of the dark cloud IC5146 - Submillimeter and NIR imaging
C. Kramer, J. Richer, B. Mookerjea +2
We present the results of a submillimeter dust continuum study of a molecular ridge in IC5146 carried out at 850micron and 450micron with SCUBA on the James Clerk Maxwell Telescope…
Mapping the submillimeter spiral wave in NGC 6946
P. B. Alton, S. Bianchi, J. Richer +2
We have analysed SCUBA 850\mum images of the (near) face-on spiral galaxy NGC 6946, and found a tight correlation between dust thermal emission and molecular gas. The map of visual…
