Parker Solar Probe Observations of High Plasma β Solar Wind from the Streamer Belt

The Astrophysical Journal Supplement Series, 2023
In general, slow solar wind from the streamer belt forms a high plasma β equatorial plasma sheet around the heliospheric current sheet (HCS) crossing, namely, the heliospheric plasma sheet (HPS).

Solar-Wind Origin

, 2019
The Sun continuously expels a fraction of its own mass in the form of a steadily accelerating outflow of ionized gas called the “solar wind.” The solar wind is the extension of the Sun’s hot (million-degree Kelvin) outer atmosphere that is visible during solar eclipses as the bright and wispy corona.

Impact of solar radiation variation on the optimal tilted angle for fixed grid-connected PV array—case study in Beijing

Global Energy Interconnection, 2018
A key design parameter for fixed grid-connected photovoltaic (PV) arrays, the optimal tilt angle, does not only depend on the geographic location but is also directly affected by atmospheric conditions.

Inherent length-scales of periodic solar wind number density structures [PDF]

, 2008
[1] We present an analysis of the radial length-scales of periodic solar wind number density structures. We converted 11 years (1995–2005) of solar wind number density data into radial length series segments and Fourier analyzed them to identify all ...

Influence of the ambient solar wind flow on the propagation behavior of interplanetary CMEs

, 2011
We study three CME/ICME events (2008 June 1-6, 2009 February 13-18, 2010 April 3-5) tracked from Sun to 1 AU in remote-sensing observations of STEREO Heliospheric Imagers and in situ plasma and magnetic field measurements.

Online evaluation method for MMC submodule capacitor aging based on CapAgingNet

Global Energy Interconnection
Submodule capacitor aging poses significant challenges to the safe operation of modular multilevel converter (MMC) systems. Traditional detection methods rely predominantly on offline tests, lacking real-time evaluation capabilities.

Modeling the Young Sun's Solar Wind and its Interaction with Earth's Paleomagnetosphere [PDF]

, 2011
We present a focused parameter study of solar wind - magnetosphere interaction for the young Sun and Earth, $~3.5$ Ga ago, that relies on magnetohydrodynamic (MHD) simulations for both the solar wind and the magnetosphere.

Characteristics of Solar Wind Density Depletions During Solar Cycles 23 and 24 [PDF]

Journal of Astronomy and Space Sciences, 2017
Solar wind density depletions are phenomena that solar wind density is rapidly decreased and keep the state. They are generally believed to be caused by the interplanetary (IP) shocks.
