The Seismic Plus Portal
E. Michel, C. Renié, K. Belkacem,M. Abed/ SPACEINN-WP3-meeting-1 21-22/10/2013 Observatoire de
Paris
Motivations & Objectives
• A large number of seismic data sources (stellar and solar) now
available (CoRoT, Kepler, SDO, etc...)
• Complementary data also necessary and numerous (spectroscopy,
interferometry, etc...)
Issue: data bases are scattered and inhomogeneous
✓ Difficult to fully exploit, need for visibility
✓ Hinders a broad community use of seismic data
Major objectives of the Portal:
✓ Coordinated access to the large variety of data sources available
✓ Provide tools to handle and combine data for a broad scientific
community
Motivations & Objectives
The Seismic Plus is intended to gather in a same well identified
place:
• Homogeneous description of the data available from various sources:
- sources of seismic data (space or ground-based) for stars and the
Sun
- sources of complementary data (space or ground-based)
commonly used in complement to seismic data to lead
interpretational studies
(e.g. fund parameters, astrometric & spectroscopic sources, models
& numerical simulation sources…)
• Tools to access and combine data from these different sources and
possibly produce new outputs
The Portal overall architecture
Three different levels have been defined (L0,L1,L2)
L0: Standard description
of the data sources
L1: Where-is-what?
(WIW)
L2: Data Access &
Handling
Access to
databases
Data Handling (tools)
The Portal overall architecture – L0
L0: Description of the data sources and tools available at the Portal
• This level is intended to provide us with a standard and
homogeneous description of available databases and tools available
at the Portal
- L0.0 : a ‘multi-approach’ presentation
Considering the potentially large number of sources, presentation
according to keywords…
• For each data source, two sub-levels of description are considered:
- L0.1 : Some general text explaining the main content of the
database (following a standard scheme tbd)
e.g.: The GAUDI database provides access to high resolution spectra collected
between XX/XX/XX and XX/XX/XX, in the framework of the COROT GroundBased Seismology Programme, it contains ...

L0: Description of the data sources and tools available at the Portal
- L0.1.1 : Field descriptions
e.g.: description of the fields as a table
needs some VO
stuff

L0 - Census of data sources:
CoRoT archive -- KASOC archive / Kepler archive -- Ground-based
✓Time series: CoRoT complementary archive -- SOHO -- SOHO/VIRGO/PMO6V -SOHO/VIRGO/DIARAD -- SOHO/VIRGOS/SPM –SOHO/GolfSOHO/MDI -SOHO/…LASCO,CELIAS/MTOF/PM/CTOF/STOF/HSTOF/SEM…? -SDO -- SDO/HMI -- SDO/AIA ? -- SDO/… -- GONG -- Bison -- MARK-I
PASTEL -- APOGEE -- P2F -- Hipparcos&Tycho
✓Fundamental parameters: catalogue –(GAIA) -- SSI Stellar Seismic

Indices
APOGEE (Sloan Digital Survey) -- GAUDI -✓Spectra:
Gaia ESO Survey (GES) -- TBL Legacy -(observed & theoretical):

✓Stellar models:

Stellar and solar models and
oscillation parameters
• In blue, database within the SPACEINN project
• CF list circulated for inquiry within SpaceInn consortium (aug. 2013)
L0 - Census of tools available in the Portal:
• Tools will appear at different levels of the portal
• They will be whether implemented in the portal or an access will
be provided for already existing tools
Examples :
- Tools to be implemented:
a broad community will be interested in accessing seismic estimates of
masses, radii for a large number of stars
SSI (seismic
indices)
Database of groundbased obs (Teff)
Tool
=
scaling relations
Output
=
seismic masses,
radii
L0 - Census of tools available in the Portal:
Examples :
- Already existing
tools:
visualize specific data to evaluate their
interest (look at a spectrum, an image, a
time series…)
One can use already existing tools such as TOPCAT
(Tool for OPerations on Catalogues And Tables,
http://www.star.bris.ac.uk/~mbt/topcat/)
The portal will use/give access to this tool - no implementation needed
The Portal overall architecture – L1
L1: Where-Is-What? (WIW)
For a given request (e.g., a list of stars), it provides (at least):
The Gaudi data base
provides access to high
resolution spectra
collected from XX/…
- list of sources where data exist,
- Access to description of the source content

Possible types of requests – L1
✓For stars:
• List of stars (use of a cross-identifyer, CDS)
• Selection by coordinates + magnitude range
• Type of star (main-sequence / red-giant / etc...)
• Type of variable star (solar-like pulsator / delta-scuti /
etc...)
• Other?
✓For the Sun:
✓For stars & the
Sun:
• period(s) of time
•remarquable events(high activity,…)
• Obs technique/Spectral domain ?
• Coordinates (for resolved observation of the Sun)
• Other?
• Data type (e.g. time series / spectro / imagery / etc...)
• Other?

L2: Data access & Handling
Data Access from selected sources to :
• Visualize specific data to evaluate their interest (look at a
spectrum, an image, a time series…)
• Download them on his personal computer to exploit them
(according to a list, a selection by position or magnitude…)
Quick look image: light-curve,
