X-Ray flares in Orion Young Stars. II. Flares, Magnetospheres, and Protoplanetary Disks
, 2008 We study the properties of powerful X-ray flares from 161 pre-main sequence (PMS) stars observed with the Chandra X-ray Observatory in the Orion Nebula region.

THE KEPLER CATALOG OF STELLAR FLARES [PDF]
The Astrophysical Journal, 2016 ABSTRACT 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.

Rheumatologic Manifestations of Patients With Type B Insulin Resistance
Arthritis Care &Research, EarlyView.Objective The objectives of this study were to identify laboratory and clinical features associated with type B insulin resistance (TBIR), a rare condition caused by autoantibodies that inhibit the insulin receptor, most frequently occurring in the setting of systemic lupus erythematosus (SLE), and to increase awareness of this rare, life‐threatening ...

Flare Hunting in Hot Subdwarf and White Dwarf Stars from Cycles 1–5 of TESS Photometry
The Astrophysical Journal Supplement SeriesStellar flares are critical phenomena on stellar surfaces, which are closely tied to stellar magnetism. While extensively studied in main-sequence (MS) stars, their occurrence in evolved compact stars, specifically hot subdwarfs and white dwarfs (WDs ...

Constraining the Origin of Magnetar Flares [PDF]
, 2014 Sudden relaxation of the magnetic field in the core of a magnetar produces mechanical energy primarily in the form of shear waves which propagate to the surface and enter the magnetosphere as relativistic Alfv\'en waves.

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 ...

Stellar Flare Study of nearby Young Moving Group Members with TESS Data
The Astrophysical JournalWe analyze TESS data to explore stellar flares and rotational characteristics in members of nearby young moving groups (NYMGs). Our study focuses on 417 members of NYMGs aged 10–150 Myr.

Seismological insights into solar and stellar magnetic activity cycles
EPJ Web of Conferences, 2017 The Sun’s magnetic activity cycle varies primarily on a time scale of approximately 11yrs from minimum to maximum and back again. It is well-known that the properties of the Sun’s acoustic oscillations are affected by the near-surface internal magnetic ...

Properties of PSR J1023+0038 Based on Kepler, TESS, and FAST
The Astrophysical Journal, 2023 The pulsar system PSR J1023+0038 is a very interesting binary with radio millisecond pulsar and low-mass X-ray binary transitions, which depend on the stellar accretion process. We have used Kepler light curves with 1 minute cadence and TESS light curves

Arthritis Care &Research, EarlyView.Objective Clinical response to mycophenolic acid (MPA) is highly heterogeneous; thus, therapeutic drug level monitoring (TDM) may help improve treatment efficacy. This systematic review and meta‐analysis examined therapeutic ranges for MPA levels associated with better outcomes and safety in patients with systemic lupus erythematosus (SLE ...
