Cosmic dust is present in many astrophysical objects, and recent observations across the
electromagnetic spectrum show that the dust distribution is often strongly three-dimensional …

Aims. We model the synthesis of molecules and dust in the inner wind of the oxygen-rich
Mira-type star IK Tau by considering the effects of periodic shocks induced by the stellar …

We present new Herschel photometric and spectroscopic observations of Supernova 1987A,
carried out in 2012. Our dedicated photometric measurements provide new 70 μm data and …

Theoretical models predict that core-collapse supernovae (CCSNe) can be efficient dust
producers (0.1-1.0 M⊙), potentially accounting for most of the dust production in the early …

Whether supernovae are major sources of dust in galaxies is a long-standing debate. We
present infrared and submillimeter photometry and spectroscopy from the Herschel Space …

Noble gas molecules have not hitherto been detected in space. From spectra obtained with
the Herschel Space Observatory, we report the detection of emission in the 617.5-and …

Aims. Our goal is to study the different morphologies associated to the interaction of the
stellar winds of AGB stars and red supergiants with the interstellar medium (ISM) to follow …

Dust-obscured star formation has dominated the cosmic history of star formation, since z≃ 4.
However, the recent finding of significant amount of dust in galaxies out to z≃ 8 has opened …

Context. The interaction between stellar winds and the interstellar medium (ISM) can create
complex bow shocks. The photometers on board the Herschel Space Observatory are …

The origin of interstellar dust in galaxies is poorly understood, particularly the relative
contributions from supernovae and the cool stellar winds of low-intermediate-mass stars …
