I will talk about our studies of detecting periodic frequency shifts in asteroseismic data from Kepler and about the coupling of modes due to convection in sub-giant stars.

A concept for a next-generation solar observing network for helioseismology, magnetic fields, and activity. Status report of the SPRING Joint Research Activity under Solarnet.

SpaceInn Board

The collaborative project "SpaceInn - Exploitation of Space Data for Innovative Helio- and Asteroseismolgy" is funded under the European Union’s Seventh Framework Programme from January 2013 – December 2016. The European Helio- and Asteroseismology Network (HELAS) has initiated this project with the mission to build on the existing European strength in the field of time-domain stellar physics. In the last three years SpaceInn activities aimed to secure optimal use of the existing and planned data, from space and from the ground, in helio- and asteroseismology in order to improve access and scientific exploitation of the existing data. The main goals of the project include: -Establish coordinated archives of space- and ground-based data, as well as of the results of the analyses of these data. This includes tools for efficient data access. -Secured long-term preservation of these, often unique, data. -Coordinated utilization of the data, resulting in a much improved understanding of solar structure, dynamics and activity, as well as of stellar structure and evolution -An increased awareness of the field, amongst the general public and at all levels of the educational system, throughout Europe. In this talk I will present all these activities and the main outcome of the project.

In this talk I present the effect of advection on the solar eigenfrequencies and how it could contribute to the surface effect.
