Streamers feeding the SVS13-A protobinary system: astrochemistry reveals accretion shocks?

Faraday Discuss., 2023, 245,164-180

We analyse deuterated water (HDO) and sulfur dioxide (SO2) at high-angular resolution in the binary system SVS13-A. We propose that molecular emission is produced by an accretion shock at the interface between the accretion streamer and the disk.

Predicting observable infrared signatures of nanosilicates in the diffuse interstellar medium

Faraday Discuss., 2023, 245,609-619
DOI: 10.1039/D3FD00055A, Paper
Sascha T. Zeegers, Joan Mariñoso Guiu, Francisca Kemper, Jonathan P. Marshall, Stefan T. Bromley
Silicates are the main constituent of interstellar dust. Direct observations of nanometre-sized silicate grains would provide a smoking gun for the occurrence of grain condensation in the diffuse interstellar medium.
