Sunspots are the most readily visible manifestations of solar magnetic field concentrations
and of their interaction with the Sun's plasma. Although sunspots have been extensively …

Starspots are created by local magnetic fields on the surfaces of stars, just as sunspots.
Their fields are strong enough to suppress the overturning convective motion and thus block …

Abstract The Helioseismic and Magnetic Imager (HMI) instrument and investigation as a part
of the NASA Solar Dynamics Observatory (SDO) is designed to study convection-zone …

PLATO 2.0 has recently been selected for ESA's M3 launch opportunity (2022/24). Providing
accurate key planet parameters (radius, mass, density and age) in statistical numbers, it …

Oscillations detected on the solar surface provide a unique opportunity for investigations of
the interior properties of a star. Through major observational efforts, including extensive …

The past few decades have seen dramatic progress in our understanding of solar interior
dynamics, prompted by the relatively new science of helioseismology and increasingly …

The magnetic field of the Sun is the underlying cause of the many diverse phenomena
combined under the heading of solar activity. Here we describe the magnetic field as it …

By applying time-distance helioseismology measurements and inversions to Solar and
Heliospheric Observatory (SOHO) Michelson Doppler Imager (MDI) dynamics campaign …

The Sun's supergranulation refers to a physical pattern covering the surface of the quiet Sun
with a typical horizontal scale of approximately 30,000 km and a lifetime of around 1.8 d. Its …

We review the current status of local helioseismology, covering both theoretical and
observational results. After a brief introduction to solar oscillations and wave propagation …
