A 3mm Chemical Exploration Of Small Organics In Class I YSOs
There is mounting evidence that the composition and structure of planetary systems are intimately linked to their birth environments. During the past decade, several spectral surveys probed the chemistry of […]

Formation of Complex Organic Molecules in Cold Interstellar Environments Through Non-diffusive Grain-surface And Ice-mantle Chemistry
A prevailing theory for the interstellar production of complex organic molecules (COMs) involves formation on warm dust-grain surfaces, via the diffusion and reaction of radicals produced through grain-surface photodissociation of […]

Ingredients For Life Appear In Stellar Nurseries Long Before Stars are Born
Complex organic molecules that could serve as building blocks for life are more ubiquitous than previously thought in cold clouds of gas and dust that give birth to stars and […]

Formation Of Aqua Planets With Water Of Nebular Origin
Recent detection of exoplanets with Earth-like insolation attracts growing interest in how common Earth-like aqua planets are beyond the solar system. While terrestrial planets are often assumed to capture icy […]

Submillimetre and Far-infrared Spectroscopy Of Monodeuterated Amidogen radical (NHD): Improved Rest-frequencies For Astrophysical Observations
Observations of ammonia in interstellar environments have revealed high levels of deuteration, and all its D-containing variants, including ND3, have been detected in cold prestellar cores and around young protostars. […]

Propargylimine In The Laboratory And In Space: Millimetre-wave Spectroscopy And First Detection In The ISM
Small imines containing up to three carbon atoms are present in the interstellar medium. As alkynyl compounds are abundant in this medium, propargylimine thus represents a promising candidate for a […]

Astrochemistry During The Formation Of Stars
Star-forming regions show a rich and varied chemistry, including the presence of complex organic molecules – both in the cold gas distributed on large scales, and in the hot regions […]

Ancient Micrometeoroids Carried Specks Of Stardust And Water To Asteroid 4 Vesta
The formation of our solar system was a messy affair. Most of the material that existed before its formation — material formed around other, long-dead stars — was vaporized, then […]

From Dust To, Possibly, Life – Complex Astrochemistry On Thin Ice Covering Dust Grains
Astronomers from the Max Planck Institute for Astronomy and the University of Jena have obtained a clearer view of nature’s tiny deep-space laboratories: tiny dust grains covered with ice. Instead […]
