Scientific rationale

Since the successful operation of asteroseismic space missions, such as CoRoT and Kepler, the field of asteroseismology has developed strongly. The space data is providing a breakthrough for some areas of investigation, and is creating new challenges for others. It has become clear that a seismic study requires a close collaboration between observers, analysts, modelers, and theoreticians, and goes hand in hand with combining information from space and ground-based data. Moreover, the link between asteroseismologists and exoplanet researchers is becoming tighter.

 

The Iberian astrophysical community includes experts in different aspects of seismic and exoplanetary studies. It is a very active community in the development and organization of new space and ground-based projects (such as PlanetVision, SONG, CARMENES, ESPRESSO, PLATO,...), and the analysis, modelling and theoretical interpretation of ground-based and space data for planets and different types of pulsators.

 

In the fifth edition of the Iberian Meeting on Asteroseismology we will focus on "Synergies between exoplanet studies and seismology of their host stars" and invite the Iberian exoplanetary community to join the asteroseismologists to exchange ideas and work out synergies between the study of planets and their host star. Moreover, we aim at assessing the progress of inter-institutional projects, intensively work on SONG, CoRoT, Kepler, PlanetVision, PLATO, CARMENES, and ESPRESSO related projects, and stimulate new projects and collaborations. We intend to discuss spectroscopic and photometric ground-based observations, the development of new instrumentation on the ground and in space, the implementation of analysis tools, and stellar/planetary modelling.

 

The meeting will consist of a few presentations to present the current status of ongoing scientific activities and to introduce new projects. All attending PhD students are encouraged and requested to present their research work. The majority of the time will be devoted to the actual workshop, where the participants work together in little groups on specific projects. The scientific program will be defined by the actual participants. Possible discussion groups and topics are:

 

1. Synergies between the study of planets and seismology of their host star

  • Seismic characterization of planet-hosting stars
  • Influences from the signal of the host star (oscillations, granulation, activity) on the signal of the planet
  • Evolution of star-planet systems
  • PlanetVision: description and work packages
  • The future of Plato

2. New ground-based instrumentation

  • SONG: status and possible iberian projects
  • CARMENES: status
  • ESPRESSO: status

3. Data analysis and data analysis tools

  • Analysis of photometric space data
  • Ground-based and space-based characterization of A-F stars
  • Solar-like oscillators observed by CoRoT and Kepler
  • Pulsations in compact pulsators
  • Atmospheric stellar parameters
  • VO tools for asteroseismology

4. Seismic and planetary models

  • Comparison between different models
