  1. MIS: science with VO Contributions from F. Boone, C. Bot, J.M. Désert, M.L. Dubernet, F. Le Petit, A. Walters M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  2. Observations/Analyses Spectres - Images Modélisations Astrophysiques Physico-Chimie des processus microscopiques Calculs théoriques Résultats expérimentaux Thèmes: Physico-Chimie matière proto-stellaire et proto-planétaire Spectroscopie de matière interst. Dans les galaxies Complexité moléculaire Caractérisation, évolution physico-chimie des grains interstellaires Approche Multi-Disciplinaire Herschel, ALMA, APEX, IRAM ISO, Spitzer VLT, CFHT HST, FUSE M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  3. Pre – VO work for Spectral Analysis • Assessment of needs and quality • Codes: PDR, radiative transfer for water • Spectroscopic data, Collisional data: working groups for needs • Reactive processes: in progress • Build the relevant services including quality control • Basecol: collisional data • CDMS/JPL: MoU • Code PDR (cf talk of F. Le Petit) • Design interfaces: • CASSIS (A. Walters), ASAP (F. Boone) M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  4. Scientific cases • Analyse d’images multi-longueur d’onde du MIS, émission gaz/poussière dans le petit nuage de Magellan: Caroline Bot • Codes du MIS dans le VO • Code de simulation: Franck Le Petit • BDD physique: M.L. Dubernet • BDD Spectres FUSE: Jean Michel Désert • Software CASSIS: Adam Walters • Software ASAP: Frédéric Boone M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  5. Spectral Line Access Paris Observatory and ESA/ESAC ML Dubernet, P. Osuna, M. Guanazzi, J. Salgado, E. Roueff MLD acknowledges support from VO-France, MDA project (F. Genova), Paris Observatory M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  6. Project Overview (1) • Access Atomic/Molecular DB startingwith line lists • Theoretical (measured or calculated) DB • Observed line lists DB • Necessary to access complementary information in order to interpret spectra or model astrophysical media: excitation rate coefficients, etc.. • Clients: stronger evolution towards public software packages for spectral analysis and on line codes for astro. Simulation • Shared, structured, complete and documented access to AM DB • Standardisation O/I, queries, ressources ID M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  7. Overview (2) • Numerous DB are available • Atomic lines: NIST DBs, Kurucz's CD-ROM, Atomic Line List of P. Van Hoof, TOPbase, Kelly Atomic Line DB, VALD, MCHF/MCDHF Collection, D.R.E.A.M, KAERI AMODS • Molecular Lines: JPL Spectroscopic DB, CDMS, HITRAN, GEISA, NIST • Other DB: IEAE, NIFS, CHIANTI, UMIST, BASECOL, small compilations • Observed databases: ATOMDB, NIST, ... • Identification of Pbs • Different DB have similar datasets • DB have different levels of update • Lengthy to identify origin of datasets, find all relevant description of data • Useful data for a single astrophysical application are dispersed in various DB • No homogeneous description of data M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  8. Access to Lines: Data Model • Based on fundamental physics, current databases and needs in astrophysics • Current DM is centered around line for atom and molecules: electronic, vibrational, rotational transitions (couplings) • Allows for identification of • Chemical Species • Level -->Quantum State-->Quantum numbers • Origin and modification of Line • Can be used to model other processes involving transitions because a line corresponds to a transition between two levels • Could be extended to nuclear physics? M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  9. Document status and perspectives Current version: 0.2 (26/9/2005) A discussion on several – albeit mostly minor – points is ongoing Short-term goal: Version 0.3 - agreed by mid-November - will be circulated to the DM group, as well as to atomic and molecular astrophysicists for comments Ultimate goal: achieve the status of a proposed recommendation by the next InterOp meeting M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  11. Access : Query ParametersSLAP : Simple Line Access ProtocolJ. Salgado, P. Osuna, M. Guainazzi, I. Barbarisi, M.L. DubernetCurrently, version 0.1 • By wavelength_min, _max, _mid • By species: Fe I, H20, ... • By type of levels (vibration, rotation, ..) • Combined with associated processes • Would we allow search of other processes independently of lines? (next version?) M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  12. Access to Lines: questions • Registry parameters? • Wavelength range • Keywords = energies, atoms or molecules, processes • Practically how should we proceed ? • Some DB will implement VO, otherwise create VO providers • Create Web Services and vizualization tools with filters M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  13. Currently Implementing • BASECOL database: excitation rate coefficients of molecules (rotation, vibration) • Numerical data, documentation, references • Web service • VOTable output • Errors (for various T and transitions) • Tools for matching Basecol and CDMS/JPL spectroscopic database (necessary for carrying out science) M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique

  14. Summary • Exchange standards for atomic & molecular standards • Implementation for specific database • Tools to handle existing data • Registries • Still not enough to carry out science • Services are needed to complete data sets: using cheap approximations, extrapolations •  next step for Basecol (only as a webservice) •  should be provided for other processes M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique
