Rational asset pricing bubbles [PDF]

, 1995
This paper provides a fairly systematic study of general economic conditions under which rational asset pricing bubbles may arise in an intertemporal competitive equilibrium framework.

First Report of Rising‐Tone EMIC Waves Driven by the Magnetosheath High‐Speed Jet

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Magnetosheath high‐speed jets (HSJs) are pervasive transient structures with enhanced dynamic pressure in the terrestrial magnetosheath and can exert notable local impacts on the magnetopause. Although various geoeffects have been reported to be associated with HSJs, whether HSJs can drive the generation of electromagnetic ion cyclotron (EMIC)

First Observations of a Foreshock Bubble at Earth: Implications for Magnetospheric Activity and Energetic Particle Acceleration [PDF]

, 2011
Earth?s foreshock, which is the quasi-parallel region upstream of the bow shock, is a unique plasma region capable of generating several kinds of large-scale phenomena, each of which can impact the magnetosphere resulting in global effects. Interestingly,

Large‐Scale Magnetosheath Jets Formed by Shock‐Discontinuity Interactions: A Three‐Dimensional Global Hybrid Simulation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Magnetosheath high‐speed jets with enhanced dynamic pressure are common in Earth's magnetosheath and can impinge on the magnetopause, driving pronounced boundary deformation. Recent observations indicate that shock–discontinuity interactions (SDIs) can generate magnetosheath jets, but the formation mechanism is still unclear.

Relationship Between Foreshock Structures and Magnetosheath Jets

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Plasma structures with enhanced dynamic pressure know as jets are frequently observed in the magnetosheath. We examine a possible connection of these jets with structures reported in the foreshock like SLAMS or plasmoids. A statistical study of the relation of the upstream conditions and the occurrence rates of magnetosheath (MSH) jets and ...

Multipoint Observations of a SLAMS Evolution and Its Merger With Whistler Waves

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We report multipoint observations of a merger between a Short Large‐Amplitude Magnetic Structure (SLAMS) and 1‐Hz whistler wave packets upstream of Earth's quasi‐parallel bow shock. Using high‐resolution data from the Magnetospheric Multiscale (MMS) mission in a string‐of‐pearls configuration, we track the SLAMS as it evolves, exhibiting ...

Different Transient Phenomena at the Edges of Traveling Foreshocks

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Past kinetic simulations and spacecraft observations have shown that traveling foreshocks (TFs) are bounded by either foreshock compressional boundaries (FCBs) or foreshock bubbles (FBs). Here we present four TFs with a different kind of structure appearing at one of their edges.

Determining the Magnetopause Location With SMILE‐SXI Using a Constrained Solar Wind Independent SWCX Model

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract The soft X‐ray imager (SXI) on the SMILE mission promises to revolutionize our understanding of the magnetopause by observing solar wind charge exchange emission from the magnetosheath on a global scale. The primary goal of this instrument is to infer the position and shape of the magnetopause from these images.

Spontaneous Hot Flow Anomalies in Earth's Foreshock

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract In recent years, we have learned that foreshock transients play an influential role in solar wind coupling with Earth's magnetosphere. These transients include spontaneous hot flow anomalies (SHFAs), which are characterized by dips in magnetic field magnitude and ion density, enhanced temperature, decelerated and deflected solar wind flow, and

Energy Conversion and Exchange in a Magnetosheath Jet

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Magnetosheath jets are regions with an extremely large dynamic pressure compared to that of the background plasma. We present a case study of a magnetosheath jet examining energy conversion processes and its interaction with the surrounding magnetosheath plasma.
