Organic Matter in the Enstatite Chondrite Sahara 97096 (EH3)
The insoluble organic matter (IOM) of an unequilibrated enstatite chondrite Sahara (SAH) 97096 has been investigated using a battery of analytical techniques. As the enstatite chondrites are thought to have […]

Modeling Complex Organic Molecules in Dense Regions
Recent observations have revealed the existence of Complex Organic Molecules (COMs) in cold dense cores and prestellar cores. The presence of these molecules in such cold conditions is not well […]

Infrared Spectra and Chemical Abundance of Methyl Propionate in Icy Astrochemical Conditions
We carried out an experiment in order to obtain the InfraRed (IR) spectra of methyl propionate (CH3CH2COOCH3) in astrochemical conditions and present the IR spectra for future identification of this […]

Search for Methylamine in High Mass Hot Cores
We aim to detect methylamine, CH3NH2, in a variety of hot cores and use it as a test for the importance of photon-induced chemistry in ice mantles and mobility of […]

Complex organic molecules in protostellar environments in the SKA era
Molecular complexity builds up at each step of the Sun-like star formation process, starting from simple molecules and ending up in large polyatomic species. Complex organic molecules (COMs; such as […]

Astrochemistry at Work in the L1157-B1 Shock: Acetaldehyde Formation
The formation of complex organic molecules (COMs) in protostellar environments is a hotly debated topic. In particular, the relative importance of the gas phase processes as compared to a direct […]

Nuclear Fragments Could Help Uncover Origins of Life-supporting Planets
New research published today in the journal Physical Review Letters describes how recreating isotopes that occur when a star explodes, can help physicists understand where life-supporting elements may be found […]

New Insight Into Solar System Transition Disk Phase by Unusual Meteorite Isheyevo
Many aspects of planet formation are controlled by the amount of gas remaining in the natal protoplanetary disk (PPDs). Infrared observations show that PPDs undergo a transition stage at several […]

Chemistry and Spatial Distribution of Small Hydrocarbons in UV-irradiated Molecular Clouds: the Orion Bar PDR
We study the spatial distribution and chemistry of small hydrocarbons in the Orion Bar PDR. We used the IRAM-30m telescope to carry out a millimetre line survey towards the Orion […]
