Properties of Flare Quasiperiodic Pulsations Based on a New TESS Flare Catalog
The Astrophysical Journal Supplement SeriesStellar flares are important indicators of stellar magnetic activity and have been widely studied. Detailed studies of flares have raised new questions. For example, the quasiperiodic pulsation (QPP) phenomenon in flares challenges standard flare models,

Advances in Understanding Solar and Stellar Flares
, 2016 Flares result from the sudden reconnection and relaxation of magnetic fields in the coronae of stellar atmospheres. The highly dynamic atmospheric response produces radiation across the electromagnetic spectrum, from the radio to X-rays, on a range of ...

Stellar Chromospheric Variability
, 2021 Cool stars with convective envelopes of spectral types F and later tend to exhibit magnetic activity throughout their atmospheres. The presence of strong and variable magnetic fields is evidenced by photospheric starspots, chromospheric plages and ...

Blackbody temperature of 200+ stellar flares observed with the CoRoT satellite
, 2022 We estimated blackbody temperature for 209 flares observed at 69 F-K stars, significantly increasing the number of flare temperature determinations. We used the Blue and Red channels obtained by the 27 cm telescope of the CoRoT satellite at high cadence ...

Arthritis Care &Research, EarlyView.Objective Race and household income impact outcomes in patients with rheumatic conditions; however, their role in pediatric antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) remains poorly understood. We aimed to evaluate whether race and ethnicity and household income are associated with severe AAV disease and renal outcomes among

The unified phenomenological model of light curves of stellar flares
, 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 Although the definition of a gout flare is well established, the state of gout flare resolution has not yet been defined. This study aimed to explore patients’ experiences and perceptions of gout flare resolution. Methods Semistructured interviews were conducted with 24 people with gout, guided by open‐ended questions exploring their ...

Detecting Stellar Coronal Mass Ejections via Coronal Dimming in the Extreme Ultraviolet
The Astrophysical JournalStellar flares and coronal mass ejections (CMEs) can strip planetary atmospheres, reducing the potential habitability of terrestrial planets. While flares have been observed for decades, stellar CMEs remain elusive.
