New Approach to Superflare Energy Determination

The Astrophysical Journal Letters
We present a new method for estimating the total energy radiated by stellar flares in broadband continua, which assumes a constant emitting area but incorporates a time-dependent temperature evolution.

Solar Neighborhood Flare Stars – a Review [PDF]

Symposium - International Astronomical Union, 1975
Since Gershberg's (1970a) very thorough review of the subject, numerous papers dealing with the collective properties of flare stars have appeared (Petit, 1970; Kunkel, 1970d, 1973; Ambartsumian and Mirzoyan, 1971; Gurzadyan, 1971; Oskanian and Terebizh, 1971a, b; Gershberg, 1972; Veeder, 1973).

Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System

Advanced Materials, EarlyView.
A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

Searching for Stellar Activity Cycles Using Flares: The Short- and Long-timescale Activity Variations of TIC-272272592

The Astronomical Journal
We examine 4 yr of Kepler 30 minutes data, and five sectors of Transiting Exoplanet Survey Satellite 2 minutes data for the dM3 star KIC-8507979/TIC-272272592. This rapidly rotating ( P = 1.2 day) star has previously been identified as flare active, with

The statistical analyses of flares detected in B band photometry of UV Ceti type stars

, 2012
In this study, we present the unpublished flare data collected from 222 flares detected in the B band observations of five stars and the results derived by statistical analysis and modeling of these data.

Old disk flare stars.

The Astronomical Journal, 1974
At least ten of the known UV Ceti-type flare stars in the solar neighborhood have old disk space motions. Five others have large space motions and are probably also members of the old disk population. The existence of flare stars with old disk space motions and also the existence of some flare stars below the main sequence complicates the picture of ...

Trackable Tolerogenic Macrophages Integrate PD‐L1 and Rapamycin Signaling to Suppress Alloimmune Responses in Transplantation

Advanced Science, EarlyView.
We developed a macrophage‐based therapeutic platform, termed trackable tolerogenic macrophages (TTM), for dual‐function immunomodulation and visualization in vivo. TTM cells were engineered to overexpress PD‐L1, incorporate bioorthogonal cell surface tags, and load rapamycin for sustained release.

Analysis of the Stellar Occultations during the Unprecedented Long-duration Flare

The Astrophysical Journal Letters
In strong stellar and solar flares, flare loops typically appear during the decay phase, providing an additional contribution to the flare emission and, possibly, obscuring the flare emission.

Polydopamine‐Encapsulated Probiotics Restore Gut Homeostasis and Reinstate Macrophage Efferocytosis in Systemic Lupus Erythematosus

Advanced Science, EarlyView.
Polydopamine‐encapsulated probiotics restore gut homeostasis and reinstate macrophage efferocytosis, thereby reestablishing immune tolerance and mitigating systemic autoimmunity, highlighting a bioengineered microbiota‐based therapeutic strategy for SLE.
