Evolution and Explosion of Very Massive Primordial Stars
A. Heger, S. E. Woosley, I. Baraffe +1
While the modern stellar IMF shows a rapid decline with increasing mass, theoretical investigations suggest that very massive stars (>100 solar masses) may have been abundant in th…
Evolutionary models for low-mass stars and brown dwarfs: uncertainties and limits at very young ages
I. Baraffe, G. Chabrier, F. Allard +1
We analyse pre-Main Sequence evolutionary tracks for low mass stars with masses $m \le 1.4 \msol$ based on the Baraffe et al. (1998) input physics. We also extend the recent Chabri…
The Substellar Mass Function in sigma Orionis
V. J. S. Bejar, E. L. Martin, M. R. Zapatero Osorio +7
We combine results from imaging searches for substellar objects in the sigma Orionis cluster and follow-up photometric and spectroscopic observations to derive a census of the brow…
Period - magnitude relationships in BVIJHK-Bands for fundamental mode and first overtone Cepheids
I. Baraffe, Y. Alibert
We present theoretical period - magnitude relationships for Cepheids in different filters for fundamental and first overtone pulsators, completing the work by Alibert et al. (1999)…
