The Astrophysical Journal, 2023 DQ Tau is a unique young high-eccentricity binary system that exhibits regular magnetic reconnection flares and pulsed accretion near periastron. We conducted NuSTAR, Swift, and Chandra observations during the 2022 July 30 periastron to characterize X ...

Solar Physics, 1983 Optical observationd now present considerable information on the flare process. It is always associated with filaments and with simplification of existing magnetic connections, and it arises from the emergence and expansion of new flux.

Optical Photometry of Flares and Flare Statistics [PDF]
International Astronomical Union Colloquium, 1983 This review discusses optical observations of flares and the results gleaned from these. Excellent reviews of flare activity have been published in the past and one might mention in particular Kunkel (1975), Gershberg (1978) and Gurzadyan (1980). In general these have been more broadly based than the present review incorporating other aspects of flare ...

Optical Flares: Observations and Interpretations [PDF]
International Astronomical Union Colloquium, 1995 AbstractObservational results on flare stars in the Galaxy and their interpretation, based on the observational approach to early stages of stellar evolution at Byurakan, are considered. The evolutionary path of red flare stars is determined. Stellar flare activity is explained as an internal phenomenon of stars.

THE OPTICAL DEPTH OF WHITE-LIGHT FLARE CONTINUUM [PDF]
The Astrophysical Journal, 2010 The white-light continuum emission of a solar flare remains a puzzle as regards its height of formation and its emission mechanism(s). This continuum, and its extension into the near UV, contain the bulk of the energy radiated by a flare, and so its explanation is a high priority.

On Impulsive and Gradual Optical Solar Flares [PDF]
International Astronomical Union Colloquium, 1989 AbstractA comparative study of H-alpha intensity and area development of several flares is presented in an attempt to investigate characteristic features of various types of optical solar flares.

Catching profound optical flares in blazars
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Flaring episodes in blazars represent one of the most violent processes observed in extra-galactic objects. Studies of such events shed light on the energetics of the physical processes occurring in the innermost regions of blazars, which cannot otherwise be resolved by any current instruments.

Solar-Terrestrial Physics, 2017 An electronic database has been created for 123801 solar flares that occurred on the Sun over the period from 1972 to 2010. It is based on catalogs of the Solar Geophysical Data (SGD) and Quarterly Bulletin on Solar Activity.

Optical and Ultraviolet Stellar Flare Spectroscopy [PDF]
International Astronomical Union Colloquium, 1983 As for solar flares, one of the most physically revealing types of data for M-dwarf flares are high-resolution, time-resolved spectra. Due to the intrinsically faint nature of the M-dwarf stars, spectroscopic data has tended to be of low spectral (˜ 5 Ǻ) and temporal (˜ 5 min) resolution. However, with the development of image intensified spectrographs
