Flare stars at radio wavelengths [PDF]
, 1989 The radio emission from dMe flare stars is discussed using Very Large Array and Arecibo observations as examples. Active flare stars emit weak, unpolarized, quiescent radio radiation that may be always present.

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.

Advanced Science, EarlyView.The mechanisms of microRNA cargo sorting to extracellular vesicles, important mediators of cell communication, are not fully understood. This study reveals that the microRNA‐production machinery acts as a ‘hub’ for the sorting of microRNAs to extracellular vesicles, a process regulated by dynamic organelle interactions.

Flaring Stars in a Nontargeted Millimeter-wave Survey with SPT-3G
The Astrophysical JournalWe present a flare star catalog from 4 yr of nontargeted millimeter-wave survey data from the South Pole Telescope (SPT). The data were taken with the SPT-3G camera and cover a 1500 deg ^2 region of the sky from 20 ^h 40 ^m 0 ^s to 3 ^h 20 ^m 0 ^s in ...

High‐Efficiency InGaP‐on‐Insulator Microresonator Nonlinear Conversion and Entanglement Generation
Advanced Science, EarlyView.Sulfur treatment of InGaP‐on‐Insulator (InGaP‐OI) significantly reduces surface roughness, passivates surface states, and lowers propagation loss at visible wavelengths, enabling efficient nonlinear frequency conversion and photon‐pair generation.

Advanced Science, EarlyView.Lipid mesophases provide a versatile platform for colon‐targeted delivery of biotherapeutics, protecting them from degradation while enhancing mucoadhesion and enabling localized, controlled release to the inflamed mucosa after oral or rectal administration. In a DSS‐induced colitis model, this strategy reduced disease activity, inflammatory biomarkers,

Evidence for Sympathetic Flaring in TESS Data
The Astrophysical JournalMost flares on the Sun occur at random, but there is a small percentage of “sympathetic flaring”—the triggering of one flare by another. Previously there had been no widespread confirmation of sympathetic flares on other stars. In this work, we developed

The Astrophysical Journal, 1974 Sizes of starspots on flare stars can be derived from the author's convection-cell hypothesis. The sizes are in fair agreement with those observed on YY Gem, CC Eri, and BY Dra by Bopp and Evans (1973). The hypothesis predicts that periodic brightness variations due to starspots are restricted to stars brighter than a critical absolute visual ...

, 2018 The works deals with the study of the flare stars, which is a group of stars for which sudden brightening can be observed. The work focuses on a star GJ 3236, which is a low-mass eclipsing binary and on which numerous flares have been observed.
