Program and Schedule

The program comprised introductory lectures on the atoms, molecules, and both bare and ice-coated grains that populate the interstellar medium. Topical lectures describec how these interstellar species are investigated with the assistance of laboratory experiments using various spectroscopy, synthesis, and processing techniques.

A poster session gave the participants the opportunity to present their work, regardless of its subject.

Note: the lecture on molecular spectroscopy in the microwave domain had to be moved from Tuesday to Thursday.

Tolou Sabri: As a LASSIE early stage researcher, I work on the experimental study of condensation and processing of dust in the astrophysical environments. Studying the structural and spectral properties of cosmic dust is significantly important because the formation and processing of main dust components in different astrophysical environments is not yet completely understood. For this reason, I perform gas-phase condensation techniques such as laser ablation to produce the two major cosmic dust analogues, which are nanometer-sized carbonaceous and siliceous grains. The laboratory studies on the simulation of astrophysical condensation processes allow us to figure out the final chemical composition and structure of the condensing grain. In the interstellar medium, the dust grains can be modified in structure and composition by the harsh interstellar irradiation field. Therefore, experiments to simulate the processing of grains by UV or ion irradiation in the laboratory are important to understand the cycle of dust and the corresponding modification of spectral and structural properties of the grains. The main tool to characterize dust analogue materials and their structural transformations is spectroscopy which is performed in a wide range from the FUV to the FIR. It also provides the major link to astronomical observations and the tool for identification of cosmic dust properties. In addition, high-resolution transmission electron microscopy (HRTEM) and energy-dispersive X-ray spectroscopy (EDX) are necessary to build a bridge to the morphology, structure, and chemical composition of the condensates and processed materials.

Interstellar dust consists of small grains of solid matter observed in the interstellar medium (ISM). Dust grains are produced initially in the envelopes of stars by the condensation of atoms and molecules that cool down as they flow outward. After the grains are injected into the ISM, various mechanisms can cause their destruction. It has been estimated that the rate of destruction of the grains in the ISM is faster than the rate of their production by stars. Observations, however, reveal that dust populations survive in the ISM, hence the hypothesis of a mechanism that re-forms the grains in situ. Remarkably, this mechanism would take place at the very low temperatures, between 10 and 100 K, that prevail locally. It is proposed that grains are re-formed by adsorbing atoms and molecules present in the interstellar gas phase, as depicted in fig. 1a. Only specific species become chemically bound, thus contributing to the re-formation of the grains, while the other species return eventually to the gas phase. The energy necessary to the desorption of the latter is possibly provided by interstellar radiations or by the binding chemical reactions of re-formation.

As interstellar dust is mostly composed of silicate grains and carbonaceous grains, our group studies experimentally the formation of these materials under conditions that mimic those of the re-formation of grains in the ISM. The reactions that are susceptible to bind atoms and molecules at very low temperatures are studied by inserting the reactants in superfluid helium nanodroplets [1], which have a temperature of 0.37 K (see this project). The formation of entire grains by the accretion of cold atoms and molecules is attempted by warming up and evaporating neon matrices doped with the species of interest [1-3]. The process, illustrated with fig. 1b, is monitored using UV/vis and IR spectroscopy and the grains synthesized in the experiments are further examined by electron microscopy.

Our experiments have shown that silicate grains can be re-formed at cryogenic temperatures [1-3] and that carbon molecules condense into a solid at the same low temperatures [4]. The current works concern the condensation of species comprising both silicon oxide molecules and carbon molecules. The process leads to the formation of distinct carbonaceous grains and silicate particles [5].

Program and Schedule

The program comprised introductory lectures on the atoms, molecules, and both bare and ice-coated grains that populate the interstellar medium. Topical lectures describec how these interstellar species are investigated with the assistance of laboratory experiments using various spectroscopy, synthesis, and processing techniques.

A poster session gave the participants the opportunity to present their work, regardless of its subject.

Note: the lecture on molecular spectroscopy in the microwave domain had to be moved from Tuesday to Thursday.

Tolou Sabri: As a LASSIE early stage researcher, I work on the experimental study of condensation and processing of dust in the astrophysical environments. Studying the structural and spectral properties of cosmic dust is significantly important because the formation and processing of main dust components in different astrophysical environments is not yet completely understood. For this reason, I perform gas-phase condensation techniques such as laser ablation to produce the two major cosmic dust analogues, which are nanometer-sized carbonaceous and siliceous grains. The laboratory studies on the simulation of astrophysical condensation processes allow us to figure out the final chemical composition and structure of the condensing grain. In the interstellar medium, the dust grains can be modified in structure and composition by the harsh interstellar irradiation field. Therefore, experiments to simulate the processing of grains by UV or ion irradiation in the laboratory are important to understand the cycle of dust and the corresponding modification of spectral and structural properties of the grains. The main tool to characterize dust analogue materials and their structural transformations is spectroscopy which is performed in a wide range from the FUV to the FIR. It also provides the major link to astronomical observations and the tool for identification of cosmic dust properties. In addition, high-resolution transmission electron microscopy (HRTEM) and energy-dispersive X-ray spectroscopy (EDX) are necessary to build a bridge to the morphology, structure, and chemical composition of the condensates and processed materials.
