Multiwavelength observations of a giant flare on CN Leonis [PDF]

, 2008
Aims. Flares on dM stars contain plasmas at very different temperatures and thus affect a wide wavelength range in the electromagnetic spectrum. While the coronal properties of flares are studied best in X-rays, the chromosphere of the star is observed ...

A prompt radio transient associated with a gamma-ray superflare from the young M dwarf binary DG CVn [PDF]

, 2014
On 2014 April 23, the Swift satellite detected a gamma-ray superflare from the nearby star system DG CVn. This system comprises a M-dwarf binary with extreme properties: it is very young and at least one of the components is a very rapid rotator.

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 ...

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

The 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.

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Time-dependent Stellar Flare Models of Deep Atmospheric Heating

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

The White-light Superflares from Cool Stars in GWAC Triggers

The Astrophysical Journal
M-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

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

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.

A 7 Day Multiwavelength Flare Campaign on AU Mic. IV. Quiescent Gyrosynchrotron and Gyroresonance Radiation from 12 to 25 GHz

The Astrophysical Journal
We 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–

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.
