The Discovery of an X-ray/UV Stellar Flare from the Late-K/Early-M Dwarf LMC 335 [PDF]

open access: yes, 2012
We report the discovery of an X-ray/UV stellar flare from the source LMC 335, captured by XMM-Newton in the field of the Large Magellanic Cloud. The flare event was recorded continuously in X-ray for its first 10 hours from the precursor to the late ...

The MUSCLES Treasury Survey. V. FUV Flares on Active and Inactive M Dwarfs [PDF]

open access: yes, 2018
M dwarf stars are known for their vigorous flaring. This flaring could impact the climate of orbiting planets, making it important to characterize M dwarf flares at the short wavelengths that drive atmospheric chemistry and escape.

M Dwarfs in SDSS Stripe 82: Photometric Light Curves and Flare Rate Analysis

open access: yes, 2009
We present a flare rate analysis of 50,130 M dwarf light curves in SDSS Stripe 82. We identified 271 flares using a customized variability index to search ~2.5 million photometric observations for flux increases in the u- and g-bands.

Time-resolved Ultraviolet Spectroscopy of the M-dwarf GJ 876 Exoplanetary System [PDF]

open access: yes, 2012
Extrasolar planets orbiting M-stars may represent our best chance to discover habitable worlds in the coming decade. The ultraviolet spectrum incident upon both Earth-like and Jovian planets is critically important for proper modeling of their ...

Outer structure of the Galactic warp and flare: explaining the Canis Major over-density

open access: yes, 2005
(Abridged) We derive the structure of the Galactic stellar Warp and Flare using 2MASS RC and RGB stars, selected at mean heliocentric distances of 3, 7 and 17 kpc. Our results are: (i) a clear stellar warp signature is derived for the 3 selected rings;

A new strongly X-ray flaring M9 dwarf in the solar neighborhood

open access: yes, 2003
We report on the discovery of a very low mass (VLM) star in the solar neighborhood, originally identified as an optical counterpart of a flaring X-ray source detected in the ROSAT All-Sky survey.

Some results of the coordinated observations of the red dwarf flare star EV Lac in 1986–1994 [PDF]

open access: yesInternational 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 ...

Characterizing Temperatures of Flares on the M Dwarf Wolf 359 from Simultaneous Multiband Optical Observations

open access: yesThe Astronomical Journal
We 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.

Experiences of Drainage and Associated Impacts: A Qualitative Study Among Patients With Hidradenitis Suppurativa

open access: yesJEADV 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

open access: yesThe Astrophysical Journal
Optical flares have been observed from magnetically active stars for many decades; unsurprisingly, the spectra and temporal evolution are complicated.
