Improving Predictions of High‐Latitude Coronal Mass Ejections Throughout the Heliosphere
Space Weather, 2020 Predictions of the impact of coronal mass ejections (CMEs) in the heliosphere mostly rely on cone CME models, whose performances are optimized for locations in the ecliptic plane and at 1 AU (e.g., at Earth).

Dynamical Solar Wind Forecasting Using In Situ Solar Wind Speed Observations
Space Weather, Volume 24, Issue 11, November 2026.Abstract Accurate prediction of the ambient solar wind at Earth is a key requirement for space‐weather forecasting but is limited by uncertainties in coronal boundary conditions and, to a lesser extent, heliospheric transport. We present a quantitative assessment of a solar wind forecast that uses near‐Earth in situ solar wind observations to estimate ...

Introduction to plasma astrophysics characteristics of astrophysical plasma high density plasma.
Kakuyūgō kenkyū, 1989 Property of High Density Matter with density from 1g/cm3 to 1016g/cm3 is argued. Using the equation of state for high density matter, the equilibrium structure of high density star is discussed. There are two phases of high density stars. They are white dwarf and neutron star. Each has a maximum possible mass.

Mass Cycle and Dynamics of a Virtual Quiescent Prominence
The Astrophysical JournalThe mass cycle of solar prominences or filaments is still not completely understood. Researchers agree that these dense structures form by coronal in situ condensations and plasma siphoning from the underlying chromosphere.

Global Ionospheric Responses to Four X‐Class Solar Flares in November 2025
Space Weather, Volume 24, Issue 11, November 2026.Abstract We investigate global ionospheric responses to four X‐class solar‐disk flares that occurred in November 2025 from the same solar active region, using multi‐instrument observations including GNSS, ionosonde, geomagnetic and GOES solar irradiance data. Pronounced dayside TEC enhancements are observed for three flares (#2 X1.2, #3 X5.1, and #4 X4.

A Data‐Driven Model of the Geomagnetic Storm Recovery Phase
Space Weather, Volume 24, Issue 11, November 2026.Abstract The recovery phase of geomagnetic storms poses a significant challenge for accurate space weather forecasting. Traditional models based on a constant decay rate fail to capture its prolonged and variable duration, leading to uncertainties in predicting impacts on technological systems.

Fictions, Conditionals, and Stellar Astrophysics [PDF]
, 2013 This article argues in favour of an inferential role for fictions in scientific modelling. The argument proceeds by means of a detailed case study, namely models of the internal structure of stars in stellar astrophysics.

The Effect of Field Line Tracing Height on Wang‐Sheeley‐Arge Solar Wind Predictions at Earth
Space Weather, Volume 24, Issue 11, November 2026.Abstract A key component of the widely used Wang‐Sheeley‐Arge model is the tracing of magnetic field lines in the solar corona, as that largely determines the modeled open/closed field regions and in turn the predicted large‐scale solar wind structure. However, small closed field regions interspersed among the open field lines inside coronal holes (CHs)
