Dust Enshrouded AGB Variables in the LMC
Patricia Whitelock, Michael Feast
The luminosities and periods of obscured AGB stars in the LMC are discussed using a combination of ISO and ground-based infrared photometry. The bolometric luminosities of these st…
Can Mira Variables Tell us the Chemical Abundances in Stellar Systems?
Michael Feast, Patricia Whitelock
A period-metallicity relation for oxygen-rich Miras derived from globular clusters is applied to similar variables in the galactic Bulge. The metallicity distribution in the Bulge…
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…
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…
IRAS04496-6958: A luminous carbon star with silicate dust in the Large Magellanic Cloud
Norman R. Trams, Jacco Th. van Loon, Albert A. Zijlstra +7
We describe ISO observations of the obscured Asymptotic Giant Branch (AGB) star IRAS04496-6958 in the Large Magellanic Cloud (LMC). This star has been classified as a carbon star.…
The symbiotic binary system RX Puppis: a possible recurrent nova with a Mira companion
Joanna Mikolajewska, Estela Brandi, Warren Hack +4
We present an analysis of photometric and spectroscopic observations of the symbiotic binary system RX Pup with the aims of developing a reliable binary for the system and identify…
