Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites
Meteoritics &Planetary Science, Volume 61, Issue 3, Page 351-370, March 2026.Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...

TESS Observations of Outbursts on Polars—Superflares
The Astrophysical JournalFlare events are magnetic activities on the stellar surface, which can provide us with information about the accretion behavior and evolution of polars. In this paper, we search for flare events on polars from all the available 2 minute cadence TESS data

The Astrophysical Journal, 1999 Extreme Ultraviolet Explorer (EUVE) observations of the long-duration 1992 July 15-17 flaring event on the red dwarf star AU Mic are discussed. The flare was detected in the EUVE Deep Survey (DS) Lexan/B band (65-190 A) and was made up of a large impulsive event corresponding to an increase in the extreme ultraviolet (EUV) emission by a factor of 15 ...

Flares on active M-type stars observed with XMM-Newton and Chandra. [PDF]
, 2007 M-type red dwarfs are among the most active stars. Their light curves display random variability of rapid increase and gradual decrease in emission.

Immunity, Inflammation and Disease, Volume 14, Issue 2, February 2026.Complement activation, particularly via the alternative pathway, drives inflammation and organ damage in ANCA‐associated vasculitis. This review highlights mechanistic insights, tissue and biomarker evidence, and clinical implications of targeting the C5a–C5aR1 axis.

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.First comprehensive phylogenomic study of subtribe Eurynotina using a combined dataset of 499 nuclear loci, 12 mitochondrial loci and 91 morphological characters covering all genera and species groups is presented. Eurynotina is monophyletic and genera within are redefined based on reassessment of old characters, generation of new characters, and ...

First Detection of an Ultracool Dwarf at 340 MHz: VLITE Observations of EI Cancri AB
The Astronomical JournalMagnetically driven phenomena such as flaring events and aurorae lead ultracool dwarfs (UCDs) to emit at radio frequencies. Despite decades of scrutiny, a comprehensive physical understanding of their radio emission at different frequencies remains ...
