Molecule-specific diffusion and desorption of interstellar ices on carbonaceous dust
Yi-Hsuan Chiu, Tushar Suhasaria, Cornelia Jäger +4
Interstellar ices form on dust grains in the coldest regions of molecular clouds and preserve key volatile reservoirs that could be incorporated into protoplanetary disks during st…
New measurement of the diffusion of carbon dioxide on non-porous amorphous solid water
Jiao He, Paula Caroline Pérez Rickert, Tushar Suhasaria +5
The diffusion of molecules on interstellar grain surfaces is one of the most important driving forces for the molecular complexity in the interstellar medium. Due to the lack of la…
Machine learning-accelerated chemistry modeling of protoplanetary disks
Grigorii V. Smirnov-Pinchukov, Tamara Molyarova, Dmitry A. Semenov +4
Aims. With the large amount of molecular emission data from (sub)millimeter observatories and incoming James Webb Space Telescope infrared spectroscopy, access to fast forward mode…
Chemical evolution in ices on drifting, planet-forming pebbles
Christian Eistrup, Thomas Henning
Planets and their atmospheres are built from gas and solid material in protoplanetary disks. Recent results suggest that solid material like pebbles may contribute significantly to…
Exploring refractory organics in extraterrestrial particles
Alexey Potapov, Maria Elisabetta Palumbo, Zelia Dionnet +5
The origin of organic compounds detected in meteorites and comets, some of which could serve as precursors of life on Earth, still remains an open question. The aim of the present…
Possible Ribose Synthesis in Carbonaceous Planetesimals
Klaus Paschek, Kai Kohler, Ben K. D. Pearce +5
The origin of life might be sparked by the polymerization of the first RNA molecules in Darwinian ponds during wet-dry cycles. The key life-building block ribose was found in carbo…
Ammonia, carbon dioxide and the non-detection of the 2152 cm CO band
Jiao He, Giulia Perotti, Shahnewaz M. Emtiaz +4
CO is one of the most abundant ice components on interstellar dust grains. When it is mixed with amorphous solid water (ASW) or located on its surface, an absorption band of CO at…
A likely flyby of binary protostar Z CMa caught in action
Ruobing Dong, Hauyu Baobab Liu, Nicolas Cuello +16
Close encounters between young stellar objects in star forming clusters are expected to dramatically perturb circumstellar disks. Such events are witnessed in numerical simulations…
Towards RNA life on Early Earth: From atmospheric HCN to biomolecule production in warm little ponds
Ben K. D. Pearce, Karan Molaverdikhani, Ralph E. Pudritz +2
The origin of life on Earth involves the early appearance of an information-containing molecule such as RNA. The basic building blocks of RNA could have been delivered by carbon-ri…
The CARMENES search for exoplanets around M dwarfs. Mapping stellar activity indicators across the M dwarf domain
M. Lafarga, I. Ribas, A. Reiners +19
Stellar activity poses one of the main obstacles for the detection and characterisation of small exoplanets around cool stars, as it can induce radial velocity (RV) signals that ca…
