On M dwarf flare stars

, 1966
Acoustic waves, hydromagnetic effect, and convective instability due to molecular dissociation are considered as mechanisms for flare activity in M dwarf stars. The first mechanism does not appear to be significant.

Time-dependent Stellar Flare Models of Deep Atmospheric Heating

The Astrophysical Journal
Optical flares have been observed from magnetically active stars for many decades; unsurprisingly, the spectra and temporal evolution are complicated.

Flare Activity Among Nearby Stars [PDF]

International Astronomical Union Colloquium, 1995
I selected the common objects from our Data Base on 234 UV Cet Flare Stars and Related Objects and the Third Catalogue of Nearby Stars by Gliese & Jahreiss (CNS-3). It is found that manifestation of flare activity (FA) (flares in any spectral region or photometric variability caused by spots) is observed on 143 flare stars (FS) out of the 3803 CNS ...

Adhesion‐Enhanced Engineered Probiotic for Prolonged Intestinal Retention and Calprotectin‐Responsive IBD Therapy

Advanced Science, EarlyView.
An intelligent engineered probiotic platform is developed for the precision management of inflammatory bowel disease. By integrating surface‐displayed adhesins with an inflammation‐responsive CAT‐SOD‐GPx tripartite fusion system and mucosal repair factors, this programmable system achieves prolonged intestinal retention and multi‐pronged therapy.

X-ray flaring activity of flare stars and RS CVn binaries

, 1986
In recent times, X-ray flares have been observed in several flare stars and RS CVn binaries. From an analysis of the X-ray flare observations we find a correlation between the average energy emitted in the X-ray band in flares and the bolometric ...

The flare cumulative frequencies of UV Ceti stars from different spectral types

, 2020
In this study, as a result of the photometric observations continued on nine UV Ceti type stars, examining the parameters obtained from the models of distributions of the flare equivalent durations in the logarithmic scale versus flare total durations ...

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

Advanced Electronic Materials, EarlyView.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

The Kinematic Signature of the Warp and Waves in the Milky Way Disk

The Astrophysical Journal
Using over 170,000 red clump (RC) stars selected from LAMOST and APOGEE, we conduct a detailed analysis of the stellar V _Z as a function of L _Z (or R _g ) across different ϕ bins for various disk populations.

Analisis Semburan Radio Pada Kejadian Flare Besar

, 2003
ABSTRAK Pemunculan flare di matahari terjadi karena adanya aktivitas matahari, yang pada awalnya ditunjukan dengan munculnya sunspot di permukaan matahari. Peningkatan importansi flare berkaitan dengan perkembangan grup sunspot.

Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices

Advanced Electronic Materials, EarlyView.
Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...
