Asymptotic Giant Branch (AGB) stars represent one of the main stellar sources for production of dust in the Universe. We provide a description of the formation...

Interstellar dust grain alignment gives rise to polarization from UV to mm wavelengths, allowing the study of the geometry and strength of the magnetic field...

R Coronae Borealis stars (RCBs) provide an unique circumstellar environment that is hydrogen-deficient, helium-rich and carbon-rich in which dust condensation...

Telescopes on La Palma and at La Silla have been used to compare dust extinction in external galaxies with our own Galaxy.

Understanding the ouflows driven by Active Galactic Nuclei (AGN) is of key importance for the modern view of galaxy evolution. A recent paradigm shift in our...

Dust is present everywhere in the Universe. Dust absorbs and scatters light dimming the astrophysical sources. Precise measurements of the attenuation...

We present the results of a systematic analysis of the solid state features identified in the circumstellar environments of a large sample of evolved stars with...

Planetary nebulae (PNe) are ideal probes of dust formation and evolution in low- and intermediate- mass stars. The analysis of dust emission in the 5 to 40...

The use of red colour as the basis for selecting candidate high redshift dusty galaxies from surveys made with Herschel has proved highly successful. The...
