Mass loss from red giants in the Magellanic Clouds
Jacco Th. van Loon
The Magellanic Clouds provide the ideal laboratory for the study of mass loss and molecule and dust formation in red giants as a function of luminosity and metal abundance. I prese…
A spectroscopic survey of stars brighter than B=16.6 magnitude in omega Centauri
Jacco Th. van Loon
Using the 2dF multi-fibre instrument at the AAT, we have carried out a spectroscopic survey of over 1500 stars brighter than B=16.6 mag, which have been confirmed by the proper mot…
Pulsating AGB stars in the LMC
Jacco Th. van Loon
I give a brief review and interpretation of the evolution, mass loss and pulsation of AGB stars in the Large Magellanic Cloud.
Magnetospheric Accretion and Winds on the T Tauri Star SU Aurigae: Multi-Spectral Line Variability and Cross-Correlation Analysis
J. M. Oliveira, B. H. Foing, J. Th. van Loon +1
SU Aurigae is a T Tauri star that was well monitored during the MUSICOS 96 multi-site campaign. We present the results of the spectroscopic analysis of the circumstellar environmen…
Mass-loss rates and dust-to-gas ratios for obscured Asymptotic Giant Branch stars of different metallicities
Jacco Th. van Loon
The mass-loss rates and dust-to-gas ratios of obscured Asymptotic Giant Branch (AGB) stars are investigated for samples with different initial metallicities: in the Small and Large…
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…
