New molecules continue to be detected in hot cores, and the ALMA telescope is likely to uncover many more over the coming years. Perhaps the most exciting detections involve highly complex molecules with structures that are new to interstellar chemical networks. How can we incorporate these molecules and structures into chemical networks to make sense of new detections? I will give a brief ove ... More

Radio astronomy has been an important method for identification of molecular constituents in the interstellar medium (ISM). One way to do this is by matching microwave and millimeter wave laboratory spectra to those obtained by radio observatories. Until now, the availability of laboratory data has been sufficient to keep up with the influx of astronomical data. However, with new and upgraded obse ... More

Water and some organic molecules were found to be deuterium enriched not only toward various astronomical targets and but also in comets and meteorites. Understanding the formation processes of deuterated species may lead to know how and when those molecules are created. Although gas phase chemistry is certainly important for deuterium enrichment, the role of physicochemical processes on the grain ... More

During the formation of stars, the accretion of the surrounding material toward the central object is thought to undergo frequent and strong eruptive outbursts, followed by long periods of relative quiescence. Such episodic events have been invoked to resolve the “luminosity problem” whereby the observed luminosity of most low-mass protostars is lower than the accretion luminosity expected fro ... More

It is largely accepted that Galactic cosmic rays, which pervade the interstellar medium, originate by means of shock waves in supernova remnants [1]. Cosmic rays activate the rich chemistry that is observed in a molecular cloud [2] and they also regulate its collapse timescale [3], determining the efficiency of star and planet formation, but they cannot penetrate up to the densest part of a molecu ...

My talk will review the most recent laboratory work performed at the Sackler Laboratory for Astrophysics (Leiden University, NL), at the Blake Research Group (Caltech, US), and at the Astrochemistry Group (Open University, UK). Laboratory experiments showed that surface reaction mechanisms on cold interstellar dust grains initiate molecular chemistry through the formation of H2, and likely dominat ... More

Aromatic hydrocarbon is one of the main component of interstellar and circumstellar dust. The hydrogenation and deuteration of interstellar aromatic hydrocarbons is of particular interest for the formation of aliphatic hydrocarbons and their deuterated isotopologues. Here, we investigated the hydrogenation/deuteration reactions of amorphous solid benzene (C6H6) at low temperatures of 10–50 K. ... More

The understanding of hydrogen attachment to carbonaceous surfaces is essential to a wide variety of research fields and technologies such as hydrogen storage for transportation but also for the formation of cosmic H2 and the identification of stable PAHs in space. For coronene cations as prototypical Polycyclic Aromatic Hydrocarbon (PAH), the existence of magic numbers upon hydrogenation was unc ... More

The increasing number of detections of complex organic molecules around young stellar objects strongly suggests that they are part of the material of which planetary systems are made of. These molecules play a central role in interstellar prebiotic chemistry and may be directly linked to the origin of life. Since the hot and dense molecular cores surrounding massive stars harbor the richest chemis ... More
