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…
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…
ISO observations of obscured Asymptotic Giant Branch stars in the Large Magellanic Cloud
Norman R. Trams, Jacco Th. van Loon, L. B. F. M. Waters +8
We present ISO photometric and spectroscopic observations of a sample of 57 bright Asymptotic Giant Branch stars and red supergiants in the Large Magellanic Cloud, selected on the…
Detection of C2, CN, and NaID absorption in the AGB remnant of HD56126
Eric J. Bakker, L. B. F. M. Waters, Henny J. G. L. M. Lamers +2
We present the detection of molecular absorption lines in the optical spectrum of the post-AGB star HD56126. The C2 Phillips A^{1}Π_{u}-X^{1}Σ^{+}_{g} (1,0), (2,0), and (3,0); Swan…
