Light Echoes of Time-resolved Flares and Application to Kepler Data

The Open Journal of Astrophysics
Light echoes of stellar flares provide an intriguing option for exploring protoplanetary disks in young stellar systems. Previous work on light echoes of circumstellar disks made use of delta-function flares for modeling.

Stellar Flares: Observations and Theory [PDF]

International Astronomical Union Colloquium, 1989
AbstractPhotometric and spectroscopic observations of a very large flare on AD Leo are presented. A self consistent model of a flare corona, transition region and chromosphere is developed; in particular the chromospheric temperature distributions resulting from X-ray and EUV irradiation by coronae of various temperatures are determined.

Impact of Early Antimalarial Adherence on Future Acute Care Utilization and Cost Among Patients With Rheumatoid Arthritis and Systemic Lupus Erythematosus: A Population‐Based Study

Arthritis &Rheumatology, EarlyView.
Objective To assess the association between early antimalarial adherence and future acute care utilization and cost in a population‐based cohort of incident rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Methods All patients with incident RA/SLE and new antimalarial use in British Columbia, Canada, between January 1997 and March 2022

Stellar magnetic field manifestations: flares

, 2023
Understanding stellar magnetic fields is crucial to understanding the structure and evolution of stars. Stellar magnetic fields manifest in many different ways, on many different time scales. In this talk discuss one manifestations of magnetic fields on cool stars: stellar flares.

Treatment of a Large Cohort of Childhood Chronic Noninfectious Uveitis in a Multicentric Large Study: Adalimumab Versus Methotrexate as First‐Line Therapy

Arthritis &Rheumatology, EarlyView.
Objective Treatment of childhood chronic idiopathic uveitis (cCIU) is predominantly based on studies in juvenile idiopathic arthritis–associated uveitis and expert opinion. Our aim was to report the treatment outcomes of our cohort of cCIU. Methods Retrospective multicenter study involving the rheumatology and ophthalmology units at Florence, Italy ...

High-time-cadence Spectroscopy and Photometry of Stellar Flares on M-dwarf YZ Canis Minoris with Seimei Telescope and TESS. II. Statistical Properties of Blue/Red Asymmetries in the Hα Line

The Astrophysical Journal
M-dwarfs frequently produce flares, and their associated coronal mass ejections (CMEs) may threaten the habitability of close-in exoplanets. M-dwarf flares sometimes show prominence eruption signatures, observed as blue/red asymmetries in the H α line ...

Validation of International Classification of Diseases Code–Based Case Definitions of Immune Checkpoint Inhibitor–Associated Inflammatory Arthritis From Administrative Health Data

Arthritis &Rheumatology, EarlyView.
Objective Immune checkpoint inhibitors (ICIs) for cancer can lead to immune‐related adverse events, including ICI‐associated inflammatory arthritis (ICI‐IA). There are no validated International Classification of Diseases (ICD) code–based case definitions for ICI‐IA.

Immune Complexes Shape the Pathogenicity of Autoantibodies in Systemic Autoimmune Diseases: Insights From an FcγRIIIA‐Reporter Assay

Arthritis &Rheumatology, EarlyView.
Objective Immune complexes (ICs), formed by autoantigen and autoantibody, play a pathogenic role in systemic autoimmune diseases through stimulation of Fcγ receptors (FcγR). However, studies investigating bioactivity of circulating ICs across various diseases remain limited.
