HAO Research Highlights

MGITM-calculated horizontal distributions
August 24, 2018

Wang and others present a global, time-dependent simulation of the Mars upper atmospheric responses to an X8.2-class solar flare event on 10 September 2017.

Painting the dips of a magnetic skeleton results in sheet-like prominences
August 24, 2018

Magnetic fields suspend the relatively cool material of solar prominences in an otherwise hot corona. A comprehensive understanding of solar prominences ultimately requires complex and dynamic models, constrained and validated by observations spanning the solar atmosphere.

A 3D MHD simulation of the eruption of a prominence-carrying coronal flux rope
August 6, 2018

Yuhong Fan and others carry out magnetohydrodynamic (MHD) simulations of the quasi-static evolution and eruption of a twisted coronal flux rope under a coronal streamer built up by an imposed flux emergence at the lower boundary.

Long-lasting response of the global thermosphere and ionosphere
August 5, 2018

Explains Wenbin Wang and others, previous studies have been devoted to examining the ionosphere and thermosphere response during the solar eclipse, but the post-eclipse response of the global ionosphere and thermosphere has not previously been well quantified.

Polar maps of differential TEC
August 4, 2018

It has long been recognized that during solar eclipses, the ionosphere-thermosphere system changes greatly within the eclipse shadow, due to the rapid reduction of solar irradiation.
