STARK-BDatabase for "Stark" broadening of isolated lines of atoms and ions

in the impact approximation

Theoretical widths and shifts contained in more than 100 publications (1984-2011)•Theory and Numerical code created by S. Sahal-Bréchot (1969 first version, 1974 complex atoms, 1977 addition of Feshbach resonances for

ions): SCP (about 6-8 basic papers)

•Updated by 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

STARK-B

• http://stark-b.obspm.fr/ • This database is devoted to modellisation and

spectroscopic diagnostics of stellar atmospheres and envelopes, and for stellar spectra synthesis. In addition, it is also devoted to laboratory plasmas, fusion plasma, laser equipment design and modelisation and technological plasmas.

PRECURSOR BELDATA

• We started to work in 1998• BELDATA WORKED AT ASTRONOMICAL

OBSERVATORY IN BELGRADE UNTIL 2002 • ON 2008 BELDATA IS RENAMED IN STARK-B

VAMDC Idea

• Problems in A&M data community

• -LACK OF STANDARDS AND COMMON GUIDELINES

• -INTEROPERABILITY problem – prevents productive search and data mining

• -DATA EXCHANGE problem – informal, e-mails, ASCII files…

• -OVERLAPING OF EFFORTS

VAMDC IDEA

• -Majority of developers are Astronomers, Physicists, Chemicists – NEED OF HIRING COMPUTER ENGINEERS

• -DATA IDENTIFICATION PROBLEM -XML schemata keys not only for data exchange but also for data identification

VAMDC IDEA

• -CRITICAL EVALUATION OF DATA• -CREATION OF SEARCH ENGINES THAT

MUST LOOK “EVERYWHERE” IN ORDER TO MAP A&M UNIVERSE

• NEED FOR AN ACCESSIBLE AND INTEROPERABLE e-INFRASTRUCTURE FOR A&M DATA

• FORUM OF DATA PRODUCERS, DATA USERS AND DATABASES DEVELOPERS

• TRAINING OF POTENTIAL USERS IN ERA AND WORLDWIDE

Virtual Atomic and Molecular Virtual Atomic and Molecular Data CenterData Center

Virtual Atomic and Molecular Data Center (VAMDC) is an European FP7 project with aims

-To build a secure, flexible and interoperable e-science environment based interface to the existing Atomic and Molecular databases

VAMDC

-To coordinate groups involved in the generation, evaluation, and use of atomic and molecular data.

-To provide a forum for training of potential users .
