Description This full-color textbook will help students and professionals understand the
space environment and its impacts on spacecraft design, engineering, and performance …

In this work the authors draw upon their expertise in geophysical and astrophysical MHD to
explore the motion of electrically conducting fluids, the so-called dynamo effect, and …

The rotational profile of the Sun is considered to be one of the key inputs in a solar dynamo
model. Hence, precise and long-term measurements of this quantity is important for our …

The recent extended minimum of solar and geomagnetic variability (XSM) mirrors the XSMs
in the nineteenth and twentieth centuries: 1810–1830 and 1900–1910. Such extended …

Abstract Information on the rotation rate of the corona, and its variation over latitude and
solar cycle, is valuable for making global connections between the corona and the Sun, for …

Aims. The main aim of the present analysis is to decipher (i) the small-scale bright features
in solar images of the quiet Sun and active regions obtained with the Atacama Large …

Context. Surface differential rotation and other global surface flows on magnetically active
stars are among the observable manifestations of the underlying stellar dynamo. Therefore …

To date, the rotational characteristics of the solar transition region remain unclear. In this
work, by applying the flux modulation method to the images derived from the Solar …

Aims. Theoretical calculations predict an increased equatorial rotation and more
pronounced differential rotation (DR) during the minimum of solar magnetic activity …

ABSTRACT A full-disk solar magnetogram has been measured each day since 1970
January 19, and the daily Magnetic Plage Strength Index (MPSI) and the daily Mount Wilson …
