Coexistence of Decaying and Decayless Kink Oscillations in a Bundle of Coronal Loops Triggered by an X6.3 Solar Flare

The Astrophysical Journal Letters
We report the coexistence of decaying and decayless kink oscillations within a single bundle of coronal loops during the X6.3-class solar flare on 2024 February 22.

The stability of solar coronal loops

The Astrophysical Journal, 1979
We have examined the stability of the ''quasi-static'' models of coronal loops. We find that all models in which the heat flux at the base of the loop is assumed to vanish are unstable to the growth of thermal perturbations. The growth rates and the profiles of the unstable modes indicate that the instability involves primarily the low-temperature ...

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, Volume 35, Issue 5, Page 689-703, September 2026.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Transverse Oscillations and Kelvin–Helmholtz Instability in Curved Arcade Loops with Siphon Flows

The Astrophysical Journal
The effect of plasma flow in curved arcade loops on transverse waves and oscillations is examined analytically. The model under study is a semicircular magnetic slab with finite transverse extensions and a mass flow inside, in the zero- β plasma ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

On the topology of global coronal magnetic fields [PDF]

, 2014
This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.

Identification of Nonlinear Damping of Transverse Loop Oscillations by KHI-induced Turbulence

The Astrophysical Journal
Kink oscillations in coronal loops have been extensively studied for their potential contributions to coronal heating and their role in plasma diagnostics through coronal seismology. A key focus is the strong damping of large-amplitude kink oscillations,

Re‐evaluation of salt of aspartame‐acesulfame (E 962) as food additive

EFSA Journal, Volume 24, Issue 9, September 2026.
Abstract The present opinion deals with the re‐evaluation of salt of aspartame‐acesulfame (E 962) as a food additive. The Panel considered that upon ingestion, E 962 dissociates into aspartame and acesulfame ions which correspond to those of the authorised sweeteners aspartame (E 951) and acesulfame K (E 950). The Panel therefore assessed the safety of

Impulsively Excited Quasiperiodic Fast-propagating Waves in the Solar Corona

The Astrophysical Journal
Quasiperiodic fast-propagating (QFP) waves excited by an impulsive, spatially localized velocity perturbation in a curved coronal loop are investigated with three-dimensional numerical simulations.

HELIOS ‐ Highly rEliable Links durIng sOlar conjunctionS

Radio Science, Volume 61, Issue 8, August 2026.
Abstract During deep space missions, maintaining reliable communication between a spacecraft and Earth becomes particularly challenging during superior solar conjunctions, when the spacecraft passes behind the Sun relative to Earth. The highly ionized solar corona and solar wind create plasma inhomogeneities that severely affect radio signals, leading ...
