Models and data combined to progress towards a better understanding of the magnetism of solar-type stars

Author: Laurene Jouve
We will review recent progress made in modeling solar-type stars in 2D and 3D in the recent years. In particular, we will focus on advances in our understanding of the dynamo processes in such astrophysical objects and the necessa ... more

What are galaxies feeding from?

Author: Jorge Sanchez Almeida
Galaxies are born in the very early Universe. Depending on their properties (mainly on their mass and environment), most of them are still forming today. Galaxies are systems that transform gas into stars, and they are still doi ... more

Stellar Inversion Techniques

Author: Daniel Reese
This course describes stellar inversion techniques. It starts with the variational principle, shows how to derive various kernels, then describes different inversion techniques (regularised least-squares, optimally-localised aver ... more

Fourier-Hankel/Legendre module for SDO data analysis pipeline

Author: Vigeesh Gangadharan
Fourier-Hankel/Legendre analysis is one of the helioseismic techniques employed to infer the internal properties of the Sun. It has been successfully applied to study p-mode interaction with sunspots and to measure sub-surface mer ... more

Dynamic balance in turbulent transport: Helicity and density-variance effects

Author: Nobumitsu Yokoi
Helicities as well as the turbulent energies are key players of the dynamo process. From viewpoint of turbulent transport, helicities mainly suppress the effective transports. In the presence of inhomogeneous large-scale flow, the ... more

Flares, oscillations and p-modes

Author: Frederic Baudin
Flares have been suspected to excite solar p-modes since the 1970s. More recently, Karoff & Kjeldsen (2008) investigated flare excitation of global oscillations while Maurya et al. (2009, 2014) did a local analysis (ring diagrams) ... more
