DOI: 10.1051/0004-6361/201629944
Abstract: The temperature of interstellar dust particles is of great importance to astronomers. It plays a crucial role in the thermodynamics of interstellar clouds, because of the gas-dust collisional coupling. It is also a key parameter… read more here.

DOI: 10.1093/mnras/stw2833
Abstract: High-resolution mid-infrared observations of astrospheres show that many of them have filamentary (cirrus-like) structure. Using numerical models of dust dynamics in astrospheres, we suggest that their filamentary structure might be related to specific spatial distribution… read more here.

DOI: 10.1093/mnras/sty2066
Abstract: Molecules with an amide functional group resemble peptide bonds, the molecular bridges that connect amino acids, and may thus be relevant in processes that lead to the formation of life. In this study, the solid… read more here.

DOI: 10.1126/science.367.6478.638-d
Abstract: Cosmic Dust Some primitive meteorites contain presolar grains, which are solid particles that formed in the interstellar medium before being incorporated into the Solar System. Presolar grains were known to be older than the Sun… read more here.
