Parker Solar Probe Observations of Energetic Particles in the Flank of a Coronal Mass Ejection Close to the Sun

Publikováno v: The Astrophysical Journal, Vol 970, Iss 1, p 98 (2024)

We present an event observed by Parker Solar Probe (PSP) at ∼0.2 au on 2022 March 2 in which imaging and in situ measurements coincide. During this event, PSP passed through structures on the flank of a streamer blowout coronal mass ejection (CME)

IS⊙IS Solar γ-Ray Measurements: Initial Observations and Calibrations

Autor: J. G. Mitchell, G. A. de Nolfo, E. R. Christian, R. A. Leske, J. M. Ryan, J. T. Vievering, M. E. Hill, A. W. Labrador, M. E. Wiedenbeck, D. J. McComas, C. M. S. Cohen, R. L. McNutt Jr., R. A. Mewaldt, D. G. Mitchell, J. S. Rankin, N. A. Schwadron

Publikováno v: The Astrophysical Journal, Vol 968, Iss 1, p 33 (2024)

High-energy neutral solar radiation in the form of γ -rays and neutrons is produced as secondary products in solar flares. The characteristics of this emission can provide key information regarding the energization of charged particles, particularly

Observations of the 2022 September 5 Solar Energetic Particle Event at 15 Solar Radii

Publikováno v: The Astrophysical Journal, Vol 966, Iss 2, p 148 (2024)

On 2022 September 5, Parker Solar Probe (Parker) observed a large solar energetic particle (SEP) event at the unprecedented distance of only 15 R _S from the Sun. The observations from the Integrated Science Investigation of the Sun (IS⊙IS) obtaine

Likely Common Coronal Source of Solar Wind and 3He-enriched Energetic Particles: Uncoupled Transport from the Low Corona to 0.2 au

Publikováno v: The Astrophysical Journal, Vol 965, Iss 1, p 54 (2024)

Parker Solar Probe (PSP) observations of a small dispersive event on 2022 February 27 and 28 indicate scatter-free propagation as the dominant transport mechanism between the low corona and greater than 35 solar radii. The event occurred during uniqu
