Kick-off meeting

A two-day meeting (May 5 and 6, 2015) will be held at the Spain National Research Council (CSIC) headquarters in Madrid. This meeting will be focused in well targetted presentations to put forward the main goals of the project and to foster further team discussions and brainstorming. The meeting will be divided into 4 sessions covering the following topics:

  • May 5 (09:30 to 10:30) General overview of the project
  • May 5 (10:30 to 13:00) Dust formation (observations, spectroscopy, chemical modelling and nucleation)
  • May 5 (15:00 to 17:30) Dust analysis (analogs, experimental techniques)
  • May 6 (09:00 to 13:30) Dust spectroscopy (astrophysical conditions) and processes (photo/thermo-processing, gas-grain interactions)
  • May 6 (15:00 to 17:00) Technical session (engineering, vacuum)
  • May 6 (17:30 to 18:30) Summary of the PIs

The final program will be posted here when available.

Meeting place and travel

The meeting will take place at the CSIC Press Room in C/ Serrano 113 (Building 113). See both the general map around CSIC and map of CSIC headquarters. See also an underground (“Metro”) map or visit this link to consult the Madrid metro in different formats.

CSIC headquarters is pretty near both from the República Argentina (line 6) and Gregorio Marañón (line 7) metro stations. The Nuevos Ministerios metro station, which connects to all the airport terminals, is 1.5 km away. These items can be checked at the general map around CSIC above.

Metro fares can be consulted here

If you consider to take a taxi from/to the airport, please visit this site. Official taxi fares can also be consulted here.

Recommended hotels
Both the NH Breton Hotel and the NH Madrid Zurbano Hotel are located pretty near from the CSIC headquarters (1 km away). Prices for a single room are around 80 euros per night.

 The Stardust machine has been designed and assembled at the Instituto de Ciencia de Materiales de Madrid (ICMM-CSIC). The elapsed time has been from October 2014 to the end of 2015. Throughout 2016, we entered into the commissioning phase with several ongoing verification experiments and processes. The article shown above is the result of this commissioning phase. From mid-2017, we are dealing with the first astrophysical experiments, the so-called exploitation phase.

The Stardust machine is basically a forefront facility to produce and analyze in-situ highly-controlled analogs of the dust grains in a versatile ultra-high-vacuum experiment (up to pressures of 10-11 mbar) to reproduce the physical conditions that prevail in the photospheres of AGB stars. In this environment, the nucleation of the aggregates and their possible interaction with the circumstellar gases will be mimicked. The Stardust machine will characterize microscopic processes (interaction with photons and gas) through surface science techniques. It encompasses 5 independent vacuum chambers, with their own instrumentation, pumping systems, gas-dosed systems in a highly-controlled ultra-high vacuum (UHV) environment:

  • MICS (Multiple Ion Cluster Source) chamber. The MICS is a new optimized route for cluster growth of a standard technique based on a sputtering gas. It allows the formation of nanoparticles of controlled elemental composition by atomic aggregation. A special port has been adapted to perform optical spectroscopy.
  • NEON (NEutral to iON) chamber that separates neutral from ionized nanoparticles as well as a mass selection. It also accelerates, simulating the radiation pressure, and anneals the formed clusters.
  • INTERACTION chamber. Interaction and chemical reactions are induced between the generated nanoparticles and molecules in the gas phase (H2, CH4, C2H2, etc).
  • INFRA chamber. In-flight analysis is performed through UV, visible, near-mid and far-infrared spectroscopy. It is expected that microwave spectroscopy will be performed with the new HEMT receivers (developed in CNIG/IGN) that will provide the opportunity to study second/minute time-dependent changes in the gas composition using these extremely sensitive radio astronomical receivers. A cryostat and a sample manipulator were acquired in order to study ice interstellar analogs.
  • ANA chamber, the analysis chamber. This allows us to collect the nanoparticles and perform X-ray photoelectron spectroscopy (XPS), thermal desorption spectroscopy (TDS), Auger electron spectroscopy (AES) and Ultraviolet photoelectron spectroscopy (UPS) in-situ. Also some in-situ processing can be performed here. The collected samples are duly transported and delivered to the AROMA setup for ulterior analysis.

In summary, the Stardust machine combines different techniques to achieve original studies on individual nanoparticles, their processing to produce complex molecules, the chemical evolution of their precursors and their reactivity with abundant astronomical molecules. The simulation chambers are equipped with state-of-the-art in situ and ex situ diagnostics.


The project


Cosmic dust is made in evolved stars. However, the processes involved in the formation and evolution of dust remain so far unknown. NANOCOSMOS will take advantage of the new observational capabilities (increased angular resolution) of the Atacama Large Millimeter/submillimeter Array (ALMA) to unveil the physical and chemical conditions in the dust formation zone of evolved stars. These observations in combination with novel top-level ultra-high vacuum experiments and astrophysical modelling will provide a cutting-edge view of cosmic dust.
