Signatures of magnetic reconnection at boundaries of interplanetary small-scale magnetic flux ropes

, 2010
The interaction between interplanetary small-scale magnetic flux ropes and the magnetic field in the ambient solar wind is an important topic to understand- ing the evolution of magnetic structures in the heliosphere.

Persistence of small-scale anisotropy of magnetic turbulence as observed in the solar wind [PDF]

, 2006
The anisotropy of magnetophydrodynamic turbulence is investigated by using solar wind data from the Helios 2 spacecraft. We investigate the behaviour of the complete high-order moment tensors of magnetic field increments and we compare the usual ...

Ion‐Scale Wave Emission and Absorption for Non‐Maxwellian Velocity Distributions in the Inner Heliosphere

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Hot and tenuous plasmas have velocity distribution functions (VDFs) significantly different from Maxwellian distributions. Characterizing how these differences impact wave damping and emission necessitates sophisticated methods for determining the associated dielectric plasma response.

Reconstructing the Geometry of a Hot Flow Anomaly With Bounding Jets in Magnetosheath

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract When interplanetary magnetic field discontinuities interact with planetary bow shocks, hot flow anomalies (HFAs) form in the solar wind and can extend into the magnetosheath. Here we reconstruct the three‐dimensional geometry of an HFA bounded by two jet regions in the terrestrial magnetosheath.

A Twenty Year Decline in Solar Photospheric Magnetic Fields: Inner-Heliospheric Signatures and Possible Implications?

, 2015
We report observations of a steady 20 year decline of solar photospheric fields at latitudes $\geq$45${^{o}}$ starting from $\sim$1995. This prolonged and continuing decline, combined with the fact that Cycle 24 is already past its peak, implies that ...

Statistical Characteristics of Stormtime Bursty Bulk Flows

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Bursty bulk flows (BBFs) play a significant role in transporting plasma earthward in the magnetotail. While their properties have been extensively studied, their behavior during geomagnetic storms needs further understanding. In this study, we investigate the stormtime characteristics of BBFs, and compare them to non‐stormtime, by performing a

Proposed Resolution to the Solar Open Magnetic Flux Problem

The Astrophysical Journal
The solar magnetic fields emerging from the photosphere into the chromosphere and corona are comprised of a combination of closed (field lines with both ends rooted at the Sun) and open (field lines with only one end at the Sun) fields.

Evolution of Anemone AR NOAA 10798 and the Related Geo-Effective Flares and CMEs

, 2008
We present a detailed examination of the features of the Active Region (AR) NOAA 10798. This AR generated coronal mass ejections (CMEs) that caused a large geomagnetic storm on 24 August 2005 with the minimum Dst index of -216 nT.

Intermittent release of transients in the slow solar wind: 2. In situ evidence [PDF]

, 2010
In paper 1, we showed that the Heliospheric Imager (HI) instruments on the pair of NASA STEREO spacecraft can be used to image the streamer belt and, in particular, the variability of the slow solar wind which originates near helmet streamers.
