Session 1 "The poor agreement between observed and predicted frequencies":
Why is so difficult to match predicted and observed oscillation frequencies for most stars? Is theory the only responsible? Might the observation technique be also responsible? In this session, discussion will be opened within two different approaches to the same physical phenomenon.

Session 3 "New instrumentation from the ground and space"
Space missions like SOHO, MOST, CoRoT & Kepler, as well as new ground-based instrumentation have been (and are being) built in order to attain very high precision of the asteroseismic data required. Do the results fulfill the expectations? A controversial example might be the g modes in the Sun and other stars. In this session, latest and relevant results of space missions and ground-based instrumentation will be presented. As well, we will discuss the relevance and necessity of new techniques and instrumentation.

Session 4 "Mode identification"
Mode identification, either individual or by means of regular patterns, is crucial for asteroseismology. Despite the progress on this issue during the last decades, the comparison between observations and models remains unclear. This session is devoted to the main problems and prospects of empirical and theoretical approaches for the mode identification.

Session 5 "Oscillations vs Activity plus planet transits"
Activity and rotation are two physical phenomena that might mimic stellar oscillations (or viceversa). In any case, all these phenomena are exhibited simultaneously by the star, and need to be disentangled. This includes the presence of planets transiting the host star.

Context and Scope
Is Asteroseismology close to really unveil the internal structure of stars? Do we need to reconsider the observational techniques, data analysis and/or to develop new theoretical approaches? After the recent results of space photometic light curves, is really meaningful the current classification of pulsating stars? Which are the primary unsolved problems that Asteroseismology must solve to make a step forward in understanding stellar evolution?
The present edition of the Stellar Pulsation Conference Series is intended to tackle these and other unsolved problems in stellar seismology.
Sessions, Talks & Discussion
In this context, the conference will be organized in six sessions distributed in four and a half days. Each session has a guiding topic (those given here below are orientative) which put in context one or several issues to be discussed in the session.
Invited speakers will present their personal view about the topic of the corresponding session. In order to encourage discussions on controversial points, round tables after each session will be organized.
Posters viewing will be available permanently. No specific session for poster viewing/presentation is foreseen.
