The Evolution of Flare Activity with Stellar Age [PDF]
Astrophysical Journal, 2019 Using a recent census of flare stars from the Kepler survey, we have explored how flare activity evolves across stellar main-sequence lifetimes. We utilize a sample of 347 stars with robust flare activity detections and which have rotation periods ...

Soft X-ray analysis of a loop flare on the Sun [PDF]
, 2004 We present the results of an analysis of soft X-ray images for a solar flare which occurred on 1992 July 11. This flare, as seen in Yohkoh Soft X-ray Telescope (SXT) images was of comparatively simple geometry, consisting of two bright footpoints early ...

Feature Ranking of Active Region Source Properties in Solar Flare Forecasting and the Uncompromised Stochasticity of Flare Occurrence [PDF]
Astrophysical Journal, 2019 Solar flares originate from magnetically active regions (ARs) but not all solar ARs give rise to a flare. Therefore, the challenge of solar flare prediction benefits from an intelligent computational analysis of physics-based properties extracted from AR

The Kepler Catalog of Stellar Flares [PDF]
, 2016 A homogeneous search for stellar flares has been performed using every available Kepler light curve. An iterative light curve de-trending approach was used to filter out both astrophysical and systematic variability to detect flares.

A Hot Ultraviolet Flare on the M Dwarf Star GJ 674 [PDF]
Astrophysical Journal, 2019 As part of the Mega-Measurements of the Ultraviolet Spectral Characteristics of Low-Mass Exoplanetary Systems Hubble Space Telescope (HST) Treasury program, we obtained time-series ultraviolet spectroscopy of the M2.5V star, GJ 674.

Glucocorticoid Withdrawal in Lupus Nephritis: A Study Protocol and Literature Review
Journal of Clinical Rheumatology and Immunology, 2020 Although glucocorticoids (GCs) are the cornerstone for the treatment for systemic lupus erythematosus (SLE), they are associated with a number of adverse effects.

Simultaneous Observation of a Flux Rope Eruption and Magnetic Reconnection during an X-class Solar Flare [PDF]
, 2018 In this Letter, we present a spectacular eruptive flare (X8.2) associated with a coronal mass ejection on 2017 September 10 at the west limb of the Sun.

Saturation Levels for White-light Flares of Flare Stars: Variation of Minimum Flare Duration for Saturation [PDF]
, 2012 Taking into account results obtained from models and from statistical analyses of obtained parameters, we discuss flare activity levels and flare characteristics of five UV Ceti stars. We present the parameters of unpublished flares detected over two years of observations of V1005 Ori.

A Database of Magnetic and Thermodynamic Properties of Confined And Eruptive Solar Flares [PDF]
arXiv, 2023 Solar flares sometimes lead to coronal mass ejections that directly affect the Earth's environment. However, a large fraction of flares, including on solar-type stars, are confined flares. What are the differences in physical properties between confined and eruptive flares?

A Technique for Automated Determination of Flare-ribbon Separation and Energy Release
, 2009 We present a technique for automatic determination of flare-ribbon separation and the energy released during the course of two-ribbon flares. We have used chromospheric H$\alpha$ filtergrams and photospheric line-of-sight magnetograms to analyse flare ...
