During the last morning of the conference, a one-hour open discussion allowed the participants to debate some of the "hot" topics presented all along the meeting as well as on some of the key issues in the field mostly related with the work Prof. Michael J. Thompson studied during his carrier. The discussion covered theory and methods, current and

Rotation plays an important role in the evolution of stars. For decades rotation-age relationships have been used as surface rotation can be measured rather easily. Here we show the result of the measurement of rotation periods for a large number of Kepler solar-like stars along with their level of magnetic activity. We also study solar-like stars

The recent discovery of low-amplitude dipolar oscillation mixed modes in massive red giants indicates the presence of a missing physical process inside their cores. Stars more massive than ∼ 1.3 M ☉ are known to develop a convective core during the main-sequence: the dynamo process triggered by this convection could be the origin of a strong

About 1 out of 200 Sun-like stars has a planet with an orbital period shorter than one day: an ultrashort-period planet 1,2. All of the previously known ultrashort-period planets are either hot Jupiters, with sizes above 10 Earth radii (R ⊕), or apparently rocky planets smaller than 2 R ⊕. Such lack of planets of intermediate size (the `hot Neptune

Sunspots host a large variety of oscillatory phenomena, whose properties depend on the nature of the wave modes and the magnetic and thermodynamic structure of the spot. Umbral chromospheric oscillations exhibit significant differences compared to their photospheric counterparts. They show an enhanced power and a shorter dominant period, from waves
