The Sun's outer atmosphere is heated to temperatures of millions of degrees, and solar
plasma flows out into interplanetary space at supersonic speeds. This paper reviews our …

This review article summarizes the advancement in the studies of Earth-affecting solar
transients in the last decade that encompasses most of solar cycle 24. It is a part of the effort …

We present a new version of the Alfvén wave solar model, a global model from the upper
chromosphere to the corona and the heliosphere. The coronal heating and solar wind …

Cold, dense clouds in the interstellar medium of our Galaxy are 4–5 orders of magnitude
denser than their diffuse counterparts. Our Solar System has most likely encountered at least …

We present a new global model of the solar corona, including the low corona, the transition
region, and the top of the chromosphere. The realistic three-dimensional magnetic field is …

We perform three-dimensional numerical simulations of stellar winds of early-M-dwarf stars.
Our simulations incorporate observationally reconstructed large-scale surface magnetic …

Accurate space weather forecasting requires knowledge of the trajectory of coronal mass
ejections (CMEs), including any deflections close to the Sun or through interplanetary space …

We perform and analyze the results of a global magnetohydrodynamic simulation of the fast
coronal mass ejection (CME) that occurred on 2011 March 7. The simulation is made using …

We present a first-principles-based coronal mass ejection (CME) model suitable for both
scientific and operational purposes by combining a global magnetohydrodynamics (MHD) …

We extend our earlier Particle Acceleration and Transport in the Heliosphere (PATH) model
to study particle acceleration and transport at a coronal mass ejection (CME)‐driven shock …
