Low energy solar particles beyond Earth and found near the sun, Using data from NASA’s Parker Solar Probe (PSP), a team led by the Southwestern Research Institute identified low-energy particles that lurk near the sun and are likely to be produced far outside Earth’s orbit through interactions with the solar wind.

The PSP is closer to the sun than other probes and carries hardware developed by SwRI.

Scientists are researching the mysterious nature of the sun to answer many questions, including protecting space travelers and technology from sunlight.

“Our main goal is to identify the acceleration mechanism that produces and transports harmful, high-energy particles from the solar atmosphere in the solar system, even near the Earth’s environment,” Dr. Mihir Desai, one of the researchers in the Integrated Solar Science Research Mission Toolkit (IS? IS), a multi-institutional project led by lead researcher Professor Dave McComas from Princeton University. Low energy solar particles beyond Earth and found near the sun.

IS? IS consists of two instruments, the High Energy Particulate Instrument (EPI-Hai) and the Low Energy Particulate Instrument (EPI-Lo). “With EPI-Lo we were able to measure very low-energy particles in an unexpected proximity to the sun’s environment.

We have considered many explanations for their existence, but in the end we found that it was smoke aimed at the interaction between slow and fast moving solar wind regions that accelerate energetic particles outside Earth’s orbit.

Some of them travel back to the sun and slow down against the solar wind waves, but still maintain very high energy.

The PSP, which travels 4 million miles from the surface of the sun, collects new solar data to help scientists understand how solar events such as solar radiation occur. B. Ejection of the coral mass affects the life of the earth. During the rising part of the solar activity cycle, our star releases large amounts of excited material, magnetic fields and electromagnetic radiation in the form of Coronal Mass Ejection (CME). Low energy solar particles beyond Earth and found near the sun.

This material is integrated into the solar wind, a constant flow of charged particles released from the upper solar atmosphere. High-energy solar particles (SEP) pose a serious radiation threat to researchers who live and work outside Earth’s orbit, and to technological assets such as space communications and satellites.

Its mission is to take the first direct measurements of low-energy populations and dangerous high-energy particles around the sun where acceleration occurs.

When solar activity slows down about every 11 years, the equatorial region of the sun flows slower than the solar wind and moves at a speed of about 1 million miles per hour, million miles per hour. Stream Regional Interaction (SIR) results from border interactions between fast and slow solar winds.

Fast-moving currents tend to outperform slower currents that appear in the western sun than they do and form turbulent interaction zones (CIR), which, unlike the shock waves generated by CME and accelerated particles.

“For the first time, we observed low-energy particles from this CIR near Mercury’s orbit,” Desai said. “We also compare PSP data with data from STEREO, other solar investigations. We hope to get a clear picture of the origin and process of these particles by measuring the full spectrum of the energy population and comparing the data with other measurements.

The next step is integrating data into the model to better understand the origins of SEP and other material. Parker’s solar investigation will solve many puzzling scientific questions and will surely produce new ones.
