Resolving the complex structure of the dust torus in the active nucleus of the Circinus galaxy
Aims. To test the dust torus model for active galactic nuclei directly, we study the extent and morphology of the nuclear dust distribution in the Circinus galaxy using high resolution…

The structure of the protoplanetary disk surrounding three young intermediate mass stars II. Spatially resolved dust and gas distribution
Aims. We present the first direct comparison of the distribution of the gas, as traced by the [O i] 6300 A emission, and the dust, as traced by the 10 μm emission, in the planet-forming region of…

The Mira variable S Orionis: relationships between the photosphere, molecular layer, dust shell, and SiO maser shell at 4 epochs
Aims. We present the first multi-epoch study that includes concurrent mid-infrared and radio interferometry of an oxygen-rich Mira star. Methods. We obtained mid-infrared interferometry of S Ori with…

GRAVITY: observing the universe in motion
GRAVITY is the second generation Very Large Telescope Interferometer instrument for precision narrow-angle as trometry and interferometric imaging. With its fibre­fed integrated optics, wavefront…
Unexpectedly large mass loss during the thermal pulse cycle of the red giant star R Sculptoris
TLDR
It is concluded that R Sculptoris is a binary system that underwent a thermal pulse about 1,800 years ago, lasting approximately 200  years, and about three times more mass was returned to the interstellar medium during and immediately after the pulse than previously thought.

New insights into the dust formation of oxygen-rich AGB stars
Context. Asymptotic giant branch (AGB) stars are one of the major sources of dust in the universe. The formation of molecules and dust grains and their subsequent expulsion into the interstellar…

The wonderful complexity of the Mira AB system
We have mapped the (CO)-C-12(3-2) line emission around the Mira AB system at 0 ''.5 resolution using the Atacama Large Millimeter/submillimeter Array (ALMA). The CO map shows amazing complexity. The…
