The Missing Symbiotic Stars: A Joint Analysis with Gaia, GALEX, and XMM-Newton Data
The Astrophysical JournalThe existence of a population of low-accretion-rate symbiotic stars (SySts), consisting of a giant star and a compact companion (usually a white dwarf), has been proposed recently. However, their population has not been fully understood. In this work, we

Hydrogel‐Based Bioelectronics: From Therapy and Sensing to Neuromorphic Computation
FlexTech, EarlyView.This review establishes a material–conduction–property–application framework connecting hydrogel chemistry and charge transport with therapy, sensing, closed‐loop feedback, and neuromorphic computation. ABSTRACT Bioelectronics establish bidirectional communication between living systems and electronic devices, providing an enabling platform for ...

The 2021 Hot-type Symbiotic Outburst of YY Herculis: An Optical Follow-up Study
The Astrophysical JournalWe have followed up on the hot-type classical symbiotic outburst reported in YY Her using the Himalayan Chandra Telescope. The outburst coincides with the secondary minima of the system.

X-rays and TESS observations of symbiotic binary stars
, 2023 Symbiotic stars are strongly interacting binaries composed of a white dwarf accreting from its red giant companion. We studied five symbiotics stars: BD Cam, V1261 Ori, NQ Gem, CD -27 8661, CD -36 8436 using observations from the Swift/XRT and XMM-Newton satellites in X-rays and from TESS in the optical.

Knowledge and Process Management, EarlyView.ABSTRACT Organisations are ceding visibility over how their employees develop knowledge. As generative AI tools become widely accessible, workers are steadily building capabilities and co‐producing knowledge through informal AI engagements that operate entirely outside sanctioned training systems.

The Astrophysical JournalWe report on the X-ray spectral and spatial evolution of the symbiotic star R Aqr. Through a multiepoch observational campaign performed with Chandra between 2017 and 2022, we study the X-ray emission of this binary system, composed of an evolved red ...

Illumination in Symbiotic Binary Stars: Non‐LTE Photoionization Models. I. Hydrostatic Case
The Astrophysical Journal, 1996 We describe a non-LTE photoionization code that calculates the atmospheric structure and emergent spectrum of a red giant illuminated by the hot component of a symbiotic binary system. The model assumes hydrostatic, radiative, and statistical equilibrium for the red giant atmosphere and solves the radiative transfer equation with a local escape ...

People and Nature, EarlyView.Abstract Conservation decisions often require navigating tensions among ecological, cultural, economic and social priorities. While debates frequently centre on single‐species outcomes, less is known about how care for landscapes may contribute to co‐stewardship.

V1047 Cen: The First Z And-type Outburst Observed in the Classical Nova Binary
The Astrophysical JournalIn 2019, the classical nova V1047 Cen experienced an unusual outburst, the nature of which has not yet been clearly determined. In this paper, we show that the 2019 V1047 Cen outburst is of Z And-type—a type that is characteristic of and has so far been ...
