Coronal Response to Magnetically Suppressed CME Events in M-dwarf Stars [PDF]
Astrophysical Journal, 2019 We report the results of the first state-of-the-art numerical simulations of coronal mass ejections (CMEs) taking place in realistic magnetic field configurations of moderately active M-dwarf stars.

Living with a Red Dwarf: FUV & X-ray emissions of dM stars and effects on hosted Planets [PDF]
, 2009 Red Dwarf (dM) stars are overwhelmingly the most numerous stars in our Galaxy. These cool, faint and low mass stars make up more than 80% of all stars. Also dM stars have extremely long life times (longer than 50-100 Gyr).

Some results of the coordinated observations of the red dwarf flare star EV Lac in 1986–1994 [PDF]
International Astronomical Union Colloquium, 1995 In 1986-94 a series of coordinated monitorings for the flare star EV Lac has been performed. The observations were aimed to collect homogeneous data on the star both in its active and quiet states, to study its flares and starspots. These photometric patrols were accompanied by monitorings of EV Lac of different other kinds: polarimetric, spectral ...

The Astronomical JournalWe present a flare temperature study of the highly active M dwarf Wolf 359 using simultaneous multiband ( u , g , r , i , and z ) photometric observations from the Lulin 1 m and 41 cm telescopes.

JEADV Clinical Practice, EarlyView.This study provides an in‐depth account of patients' experiences of drainage as a symptom of hidradenitis suppurativa. The HIDE Scale© facilitates incorporation of these insights into clinical practice, supporting person‐centred approaches that enhance clinical assessment, reduce stigma, and strengthen patient–clinician communication.

Time-dependent Stellar Flare Models of Deep Atmospheric Heating
The Astrophysical JournalOptical flares have been observed from magnetically active stars for many decades; unsurprisingly, the spectra and temporal evolution are complicated.

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites
Meteoritics &Planetary Science, EarlyView.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 ...

The White-light Superflares from Cool Stars in GWAC Triggers
The Astrophysical JournalM-type stars are the ones that flare most frequently, but how big their maximum flare energy can reach is still unknown. We present 163 flares from 162 individual M2 through L1-type stars that triggered the GWAC, with flare energies ranging from 10 ^32.2

Searching for Rotational X‐Ray Modulation on TIC 277539431
Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT TIC 277539431, a fast rotating M7 dwarf, was detected to host the highest latitude flare to date at 81°$$ {81}^{{}^{\circ}} $$. Magnetic activity like stellar flares occurring at high latitude indicate occurrence of coronal loops at these latitudes on fully‐convective M dwarfs. In contrast, sunspots usually occur below 30°$$ {30}^{{}^{\circ}} $

The Astrophysical JournalWe present an analysis of the radio quiescent data from a multiwavelength campaign of the active M dwarf flare star AU Mic (dM1e) that occurred in 2018 October. Using Ku -band data (12–18 GHz) from the Karl G. Jansky Very Large Array and K -band data (17–
