Locate a Stellar Flare from the M Dwarf LAMOST J1332+5057
The Astrophysical JournalYoung M-type stars exhibit frequent flares, which would seriously impact their habitable planets. Since stellar surfaces cannot be resolved, flare locations remain unknown.

The Astrophysical Journal Supplement Series, 2022 Stellar parameters and magnetic activity are important for the understanding of stellar physics and dynamo theory. We have used LAMOST spectroscopic surveys to study stellar parameters and magnetic activity properties of TESS objects.

The unified phenomenological model of light curves of stellar flares [PDF]
, 2003 We present a phenomenological model to explain a wide variety of stellar flares. We assume that a flare consists of a fast and relatively strong rise in brightness followed by a slow and fainter component.

Arthritis Care &Research, EarlyView.Objective Systemic lupus erythematosus (SLE) is a heterogenous inflammatory condition with widely varying global prevalence estimates. The frequency of SLE in the general population of Australia has been reported to be notably lower than contemporary estimates in countries such as the United States or United Kingdom, at 19 to 39 per 100,000 as opposed ...

Statistics of Solar White-light Flares. I. Optimization and Application of Identification Methods
The Astrophysical JournalWhite-light flares (WLFs) are energetic activity in the stellar atmosphere. However, observed solar WLFs are relatively rare compared to stellar WLFs or solar flares observed at other wavelengths, which limits our further understanding of solar/stellar ...

MEASUREMENT OF THE RATE OF STELLAR TIDAL DISRUPTION FLARES [PDF]
The Astrophysical Journal, 2014 We report an observational estimate of the rate of stellar tidal disruption flares (TDFs) in inactive galaxies, based on a successful search for these events among transients in galaxies using archival SDSS multi-epoch imaging data (Stripe 82). This search yielded 186 nuclear flares in galaxies, of which two are excellent TDF candidates. Because of the

Li production by stellar flares in young open clusters [PDF]
, 2008 The correlation observed between the Li abundance and surface activity of young cool stars is not explained by current stellar evolution models. We study the possibility that this correlation arises from significant in situ production of Li by solar-like

Flares on active M-type stars observed with XMM-Newton and Chandra. [PDF]
, 2007 M-type red dwarfs are among the most active stars. Their light curves display random variability of rapid increase and gradual decrease in emission.

X-Ray Observations of Stellar Flares [PDF]
International Astronomical Union Colloquium, 1983 ABSTRACTThe history of stellar X-ray flare observations prior to EINSTEIN is reviewed. X-ray light curves as measured by the IPC are then presented for all time resolved flare events discovered as of July 1982 in the EINSTEIN data set. These light curves are analyzed in terms of solar-like loop models to derive densities, temperatures, loop lengths ...
