Démarche d'investigation, pédagogie transmissive et principe d'autorité : l'exemple du système héliocentrique by Estelle Blanquet, Éric Picholle

“…“Doing science” involves belonging to a community and consenting to the knowledge established by others ; but il also involves questioning it to better actualizing it.The article questions the dual relationship with authority that allows to build the investigative approach. The question of heliocentrism constitutes a striking example of the difficulty to emancipate oneself from the paradigmatic pressure of the dominant culture. …”

MHD Modeling of the Background Solar Wind in the Inner Heliosphere From 0.1 to 5.5 AU: Comparison With In Situ Observations by Y. X. Wang, X. C. Guo, C. Wang, V. Florinski, F. Shen, H. Li, M. Blanc

“…To test the performance of this model, we compare the simulation results with in situ measurements from multiple spacecraft including ACE/WIND, Solar TErrestrial Relations Observatory, Ulysses, Juno, and MErcury Surface, Space ENvironment, GEochemistry, and Ranging at different latitudes and heliocentric distances. There is an overall agreement between the model results and solar wind observations at different latitudes and heliocentric distances. …”

Time-dependent Acceleration and Escape of Charged Particles at Traveling Shocks in the Near-Sun Environment by Thomas M. Do, Federico Fraschetti, Jozsef Kota, Joe Giacalone, Christina M. S. Cohen, David J. McComas

“…The average timescale for particle acceleration at various heliocentric distances, from 1 au down to the inner heliosphere (<0.1 au), is shorter than in the no-escape case, as higher energy particles have a shorter time to accelerate before completely leaving the system into the upstream medium. …”

Radial Evolution of Interplanetary Shock Properties with Heliospheric Distance: Observations from Parker Solar Probe by Oksana Kruparova, Adam Szabo, Lan K. Jian, František Němec, Jana Šafránková, Zdeněk Němeček, Jacob Pasanen, Ayris Narock, Vratislav Krupar

“…We investigate the statistical properties of these shocks, focusing on correlations between key parameters—magnetic field compression, density compression, shock normal angle, and change in velocity—and heliocentric distance. Significant positive correlations are identified between heliocentric distance and both magnetic field compression and density compression, suggesting that shocks strengthen as they propagate away from the Sun, largely due to the high local magnetosonic speeds closer to the Sun that can suppress shock formation except in extremely fast events. …”

The Juno mission as a probe of long-range new physics by Praniti Singh, Shi Yan, Itamar J. Allali, JiJi Fan, Lingfeng Li

“…Abstract Orbits of celestial objects, especially the geocentric and heliocentric ones, have been well explored to constrain new long-range forces beyond the Standard Model (SM), often referred to as fifth forces. …”

An Empirical Relationship Between Coronal Density and Solar Wind Velocity in the Middle Corona With Applications to Space Weather by Kaine A. Bunting, Huw Morgan

“…A recent advancement is to use the distribution of electron density at a heliocentric distance of 8 R⊙, gained by applying coronal rotational tomography to coronagraph data, as an inner boundary condition for the time‐dependent Heliospheric Upwind eXtrapolation solar wind model. …”

Delay of Near-relativistic Electrons with Respect to Type III Radio Bursts throughout the Inner Heliosphere by J. G. Mitchell, E. R. Christian, G. A. de Nolfo, C. M. S. Cohen, M. E. Hill, A.

“…In this study, we examine energetic electron onsets and type III radio bursts observed by the Integrated Science Investigation of the Sun (IS⊙IS) and the FIELDS Radio Frequency Spectrometer instrument on Parker Solar Probe at a variety of heliocentric distances. With these observations, we can uniquely decouple the effects of acceleration and transport and shed light on the source of these delays. …”

A Numerical Approach to Study Ablation of Large Bolides: Application to Chelyabinsk by Josep M. Trigo-Rodríguez, Joan Dergham, Maria Gritsevich, Esko Lyytinen, Elizabeth A. Silber, Iwan P. Williams

“…The casual dashcam recordings from many locations of the Chelyabinsk superbolide associated with the atmospheric entry of an 18 m in diameter near-Earth object (NEO) have provided an excellent opportunity to reconstruct its atmospheric trajectory, deceleration, and heliocentric orbit. In this study, we focus on the study of the ablation properties of the Chelyabinsk bolide on the basis of its deceleration and fragmentation. …”

Improving Predictions of High‐Latitude Coronal Mass Ejections Throughout the Heliosphere by C. Scolini, E. Chané, J. Pomoell, L. Rodriguez, S. Poedts

“…Progresses in the exploration of the inner heliosphere, however, advocate the need to assess their performances at both higher latitudes and smaller heliocentric distances. In this work, we perform 3‐D magnetohydrodynamics simulations of artificial cone CMEs using the EUropean Heliospheric FORecasting Information Asset (EUHFORIA), investigating the performances of cone models in the case of CMEs launched at high latitudes. …”

Mach Number Scaling of Foreshock Magnetic Fluctuations at Quasi-parallel Bow Shocks and Their Role in Magnetospheric Driving Throughout the Solar System by Brandon L. Burkholder, Li-Jen Chen, Katariina Nykyri, Norberto Romanelli, Menelaos Sarantos, Dave Sibeck, Jaye Verniero, Gina A. DiBraccio, Daniel Gershman, Martin Lindberg, Erin Kincade

“…The amplitude of magnetic fluctuations depends on the strength of the shock, quantified by the Alfvén Mach number ( M _A ), which is the ratio of solar wind velocity to the local Alfvén velocity. With increasing heliocentric distance, the solar wind M _A generally increases, such that Mercury typically experiences a lower M _A ∼ 5 compared to Earth ( M _A ∼ 8), and Mars a slightly higher M _A ∼ 9. …”
