The infrared spectrum of the Be star gamma Cassiopeiae
S. Hony, L. B. F. M. Waters, P. A. Zaal +6
We present the 2.4-45 micrometer ISO-SWS spectrum of the Be star gamma Cas (B0.5 IVe). The spectrum is characterised by a thermal continuum which can be well fit by a power-law S_n…
Mass-loss rates and luminosity functions of dust-enshrouded AGB stars and red supergiants in the LMC
Jacco Th. van Loon, M. A. T. Groenewegen, A. de Koter +5
A radiative transfer code is used to model the spectral energy distributions of 57 mass-losing Asymptotic Giant Branch (AGB) stars and red supergiants (RSGs) in the Large Magellani…
Wolf-Rayet nebulae as tracers of stellar ionizing fluxes: I. M1-67
P. A. Crowther, A. Pasquali, O. De Marco +3
We use WR124 (WN8h) and its associated nebula M1-67, to test theoretical non-LTE models for Wolf-Rayet (WR) stars. Lyman continuum ionizing flux distributions derived from a stella…
On the nature of the bi-stability jump in the winds of early-type supergiants
Jorick S. Vink, Alex de Koter, Henny J. G. L. M. Lamers
We study the origin of the observed bi-stability jump in the terminal velocity of the winds of supergiants near spectral type B1. To this purpose, we have calculated a grid of wind…
The composition and nature of the dust shell surrounding the binary AFGL 4106
F. J. Molster, L. B. F. M. Waters, N. R. Trams +8
We present infrared spectroscopy and imaging of AFGL~4106. The 2.4-5 micron ISO-SWS spectrum reveals the presence of a cool, luminous star (T_eff ~ 3750 K) in addition to an almost…
