Modulation of gyrosynchrotron emission in solar and stellar flares by slow magnetoacoustic oscillations [PDF]

, 2006
Gyrosynchrotron emission generated by non-thermal electrons in solar and stellar coronal flares can be efficiently modulated by slow magnetoacoustic oscillations in the flaring loops.

Patterns of X-Ray and γ-Ray Flares: From Blazar to Magnetar and Sun

The Astrophysical Journal
Using Gaussian process methods, we analyzed the light curves of three extreme solar X-ray flares observed by the RHESSI satellite. Their variability characteristics were then compared with those of HXMT-HE X-ray burst (XRB; in SGR 1935+2154) associated ...

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events

Astronomische Nachrichten, Volume 347, Issue 5, June 2026.
ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

Spectral‐Resolved Light at Night: TEMPO Observations and Background Correction

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Artificial Light at Night (ALAN) poses risks to public health and ecosystems. While long‐term remote sensing has tracked global nighttime light, spectrally resolved light at night (spectral light at night (SLAN)) data from geostationary orbit only became available with NASA's Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission. Its

Anomalous-plasmoid-ejection-induced secondary magnetic reconnection: modeling solar flares and coronal mass ejections by laser–plasma experiments

High Power Laser Science and Engineering, 2013
The driving mechanism of solar flares and coronal mass ejections is a topic of ongoing debate, apart from the consensus that magnetic reconnection plays a key role during the impulsive process.

Height‐Dependent Evolution of the Ionospheric Response to the May 2024 Superstorm: Global GNSS‐POD, GNSS‐RO, and Ground‐Based Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Capturing global ionospheric response during extreme geomagnetic storms remains a major observational challenge. During 10–11 May, 2024 superstorm, we investigate the height‐dependent response of the F‐region using multi‐constellation GNSS‐POD limb‐sounding measurements from COSMIC‐2, Spire, PlanetiQ, and FengYun‐3 satellites. Approximately 12,

Fine structure events in microwave emission during solar minimum

Solar-Terrestrial Physics, 2019
The solar minimum is a period with a relatively smaller number of sunspots and solar eruptions, and has been less studied before. Since the radio signal rapidly responds to the change of solar plasma and magnetic field, we perform a comprehensive ...

Gravity Wave Influences on MSTID Climatology Over CONUS: WACCM‐X Year‐Long Simulation and GNSS Long‐Term Observation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) are prominent wave‐like structures in the ionosphere, with complex generation mechanisms involving both atmospheric gravity waves (GWs) and electrodynamic instabilities such as the Perkins instability (PI).
