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 ...

Search for Flare Stars in TAOS Data [PDF]
, 2007 中美掩星觀測計畫的目標為測量彗星核大小至幾公里的古柏帶天體之數量與大小分佈。在毎個晴朗的夜晚，超過數百顆背景恆星由三台寬視野(3平方度)、短焦比(f/1.9)、小口徑(50公分)且配備有2k×2k CCD 相機的望遠鏡自動監控。在三台望遠鏡同時操作下，誤報率可因此降低。資料取樣頻率為5 Hz，孔徑測光可至星等約為13.7等的背景恆星。 儘管 TAOS 是為偵測掩星事件而設計，其龐大的資料量與短暫的曝光時間提供了可用於搜尋快速變化之變星的資料庫。由於毎隔0.2秒記錄一次背景恆星的光通量 ...

First Temperature Profile of a Stellar Flare Using Differential Chromatic Refraction
The Astrophysical Journal LettersWe present the first derivation of a stellar flare temperature profile from single-band photometry. Stellar flare DWF 030225.574−545707.45129 was detected in 2015 by the Dark Energy Camera as part of the Deeper, Wider, Faster program. The brightness (Δ m

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.

Flare star observations with a single-photon counting imaging detector [PDF]
, 1995 At Los Alamos National Laboratory we are developing a new imaging sensor which combines high spatial and high temporal resolution over a large area format, while maintaining single-photon counting sensitivity and substaining a high count rate.

The Astrophysical JournalM dwarfs are the most common type of star in the solar neighborhood, and many exhibit frequent and highly energetic flares. To better understand these events across the electromagnetic spectrum, a campaign observed AU Mic (dM1e) over 7 days from the X ...

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 ...

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 ...
