Giants in the globular cluster omega Centauri: dust production, mass loss and distance
Iain McDonald, Jacco Th. van Loon, Leen Decin +5
We present spectral energy distribution modelling of 6875 stars in omega Centauri, obtaining stellar luminosities and temperatures by fitting literature photometry to state-of-the-…
Molecules and dust production in the Magellanic Clouds
Jacco Th. van Loon, Martin Cohen, Joana M. Oliveira +5
We present ESO/VLT spectra in the 2.9-4.1 micron range for a large sample of infrared stars in the Small Magellanic Cloud (SMC), mainly carbon stars, massive oxygen-rich Asymptotic…
Spitzer Space Telescope evidence in NGC 6791: no super-mass-loss at super-solar metallicity to explain helium white dwarfs?
Jacco Th. van Loon, Martha L. Boyer, Iain McDonald
We use archival Spitzer Space Telescope photometry of the old, super-solar metallicity massive open cluster NGC 6791 to look for evidence of enhanced mass loss, which has been post…
A Spitzer Space Telescope Atlas of omega Centauri: The Stellar Population, Mass Loss, and the Intracluster Medium
Martha L. Boyer, Iain McDonald, Jacco Th. van Loon +4
We present a Spitzer Space Telescope imaging survey of the most massive Galactic globular cluster, omega Centauri, and investigate stellar mass loss at low metallicity and the intr…
WASP-3b: a strongly-irradiated transiting gas-giant planet
D. Pollacco, I. Skillen, A. Collier Cameron +43
We report the discovery of WASP-3b, the third transiting exoplanet to be discovered by the WASP and SOPHIE collaboration. WASP-3b transits its host star USNO-B1.0 1256-0285133 ever…
Dust, pulsation, chromospheres and their role in driving mass loss from red giants in Galactic globular clusters
Iain McDonald, Jacco Th. van Loon
Context: Mass loss from red giants in old globular clusters affects the horizontal branch (HB) morphology and post-HB stellar evolution including the production of ultraviolet-brig…
