Presentation Transcript

  1. , • VIRTUAL ATOMIC AND MOLECULAR DATA CENTER (VAMDC) AND STARK-B DATABASE • MILAN S. DIMITRIJEVIĆ

  2. Virtual Atomic and Molecular Data Center • Virtual Atomic and Molecular Data Center (VAMDC) is an European FP7 project with aims to build a flexible and interoperable e-science environment based interface to the existing Atomic and Molecular data. It is a complex project including 15 institutions with 24 scientific groups France, Serbia, Russia, England, Austria, Italia, Germanz, Sweden and Venezuela.

  3. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS), the Coordinator • CAMBRIDGE UNIVERSITY (CMSUC) • UNIVERSITY COLLEGE LONDON (UCL) • OPEN UNIVERSITY (OU) • UNIVERSITAET WIEN (UNIVIE) • UPPSALA UNIVERSITET (UU)  • UNIVERSITAET ZU KOELN (UK) • ISTITUTO NAZIONALE DI ASTROFISICA (INAF) • QUEEN´S UNIVERSITY OF BELFAST (QUB) • ASTRONOMICAL OBSERVATORY OF BELGRADE (AOB)

  4. INSTITUTE OF ASTRONOMY RAS (INASAN) • RUSSIAN FEDERAL NUCLEAR CENTRE ALL-RUSSIAN INSTITUTE OF TECHNICAL PHYSICS (RFNC-VNIITF) • INSTITUTE OF ATMOSPHERIC OPTICS SB RAS (IAO) • CORPORACION PARQUE TECNOLOGICO DE MERIDA (CECALCULA-CPTM) • INSTITUTE FOR SPECTROSCOPY RAS (ISRAN)

  5. CNRS • UNIVERSITÉ PIERRE ET MARIE CURIE • OBSERVATOIRE DE PARIS • UNIVERSITÉ DE REIMS • UNIVERSITÉ BORDEAUX 1 • UNIVERSITÉ JOSEPH FOURIER DE GRENOBLE • UNIVERSITÉ DE BOURGOGNE • UNIVERSITÉ TOULOUSE 3

  6. STARK-BDatabase for "Stark" broadening of isolated lines of atoms and ionsin the impact approximation • Calculated widths and shiftscontained in more than100 publications (1984-2009) • Theory and Numerical codecreated by S. Sahal-Bréchot(1969 first version, 1974 complex atoms, 1977 addition of Feshbach resonances for ions): SCP (about 6-8 basic papers) • Updatedby M.S. Dimitrijević and S. Sahal-Bréchot • Accuracy : about 20%, sometimes better, sometimes less • More than 1500 citations (ADS) for the whole work S. Sahal-Bréchot*, M.S. Dimitrijević**(scientists responsibles of Stark-b) and N. Moreau*(Research engineer) *Observatoire de Paris, LERMA, France ** Astronomical Observatory of Belgrade, Serbia 80% of the data are currently implemented but the database has been opened since september 2008 7

  7. In Cooperation withM. Christova (University of Sofia, Bulgaria)N. Ben Nessib (University of Carthago, Tunisia)H. Elabidi & W. Mahmoudi (University of Bizerte, Tunisia)

  8. STARK-B • Scientific objectives: Spectroscopic diagnostics, Modelisation Synthetic spectra Addresses Astrophysics Virtual Observatories Laboratory and technological plasmas

  9. Next steps and future objectives- Implementation of the remaining files(about 20)- VAMDC European project (Virtual Observatories standards,interoperability, data model, deliverables)- Create a request with the vacuum measured wavelengths (our wavelengths are calculated ones for multiplets)Link with the NIST wavelengths databases (if possible)- Implementation of our future data(SCP or quantum)- Implementation of MSE data(Modified Semi Empirical Method)byMilan Dimitrijevic et coworkersN.B. less accurate method, to be used if nothing else exists- Extension outside the impact approximation- Automatic SCP calculation code using accurate atomic structure- Create graphics and possibilities of interpolation or extrapolations for obtaining missing data (use of systematic trends)

  10. FUTURE PROJECT • STARK-C • C as code • SSB semiclassical-perturbation numerical code on line • For calculations on line widths and shifts on line

  11. БЛАГОДАРЯ ЗА ВНИМАНИЕТО ХВАЛА НА ПАЖЊИ THANK YOU FOR ATENTION
