 08:45  Welcome and "Tour de Table"

(All participants present themselves and indicate the field they are working in)

 
Session #1. Low-degree peak-bagging techniques (feedback to and from asteroseismology)
 
Session Leader: Jerome Ballot (IRAP)
 

The different strategies (global, by even-odd groups, etc) at different freq. ranges

The different minimization techniques

The length of the temporal series effect on the derived parameters

The uncertainties on the parameters and their physical meaning

Current limitations and foreseen progress

 

Short presentations (provisonal) by: Hans Kjeldsen, Enrico Corsaro, …

 
Session #2. On numerical solar inversions and the properties of the mode sets
 
Session Leader: Maria Pia di Mauro (INAF)
 

Redundant information on frequency data sets

Complementary information on frequency data sets

Observational requirements (characteristics of the modes) for a minimum meaningful inversion of stellar interiors

 

Short presentations (provisonal) by: Hannah Schunker, Antonio Eff-Darwich,..

Session #3: "Implementation of a solar activity proxy from helioseismic observations"
 
Session Leader: Rafael García (CEA-Saclay)
 

The derivation of solar activity proxies from Helioseismic observations.

From the photometric and velocity time series.
From temporal behaviour of solar eigenfrequencies (just p-modes?)
Differentiate information depending on:
    Angular degree range (low, mid and high-l)
    Frequency range,...
 

=> Agreement and definition of the associated deliverable: the Standard Photometric Helioseismic Activity proXy (SPHAX)

 

Short presentations (provisonal) by:Martin Nielsen,..

 

 
Session #4. Mid- and High-degree peak bagging techniques
 
Session Leader: Sylvain Korzennik (CfA)
 

The different strategies at different freq. ranges

The different minimization techniques

The length of the temporal series effect on the derived parameters

The uncertainties on the parameters

Current limitations and foreseen progress

=> Conceptual scheme of the peak-bagging tool to be delivered

 

Short presentations (provisonal) by:Markus Roth, David Salabert,..

Session #5.  Optimal exploitation of different simultaneous/contemporaneous data sets
 
Session Leader: Anne-Marie Broomhall (U. Warwich)
 

Different solar physical magnitudes (flux, radial velocity, etc.)

Different intrinsic noise sources and systematics

Challenge to derive a standard procedure to optimize the combined use of all data sets

=> Definition and contents of the associated deliverable

 

Short presentations (provisonal) by:David Salabert,..

 

Session #6. Summary of the workshop and wrap-up
Chairman: Antonio Eff-Darwich (ULL/IAC)
