CXOGBS J173620.2-293338: A CANDIDATE SYMBIOTIC X-RAY BINARY ASSOCIATED WITH A BULGE CARBON STAR [PDF]

The Astrophysical Journal, 2013
The Galactic Bulge Survey is a wide but shallow X-ray survey of regions above and below the Plane in the Galactic Bulge. It was performed using the Chandra X-ray Observatory's ACIS camera. The survey is primarily designed to find and classify low luminosity X-ray binaries.

Symbiotic Star T CrB as an Extreme SU UMa–type Dwarf Nova

The Astrophysical Journal Letters, 2023
T CrB is a symbiotic recurrent nova that exhibits quiescent and active phases between its classical nova eruptions. The statistical properties of these active phases have been poorly studied thus far. Because of that their nature remained unknown.

The Role of Electron Scattering in Probing the Wind from the Hot Star in Symbiotic Binaries [PDF]

Proceedings of the International Astronomical Union, 2011
AbstractWe modeled the broad wings of the OVI 1032,1038Å resonance lines and HeII 1640Å line in the spectra of some symbiotic stars by the electron-scattering process. We determined an empirical relationship between the emission measure of the symbiotic nebula and the electron optical depth. This allowed us to determine a contribution from the electron-

FM stars II: a Fourier view of pulsating binary stars - determining binary orbital parameters photometrically for highly eccentric cases [PDF]

, 2015
Continuous and precise space-based photometry has made it possible to measure the orbital frequency modulation of pulsating stars in binary systems with extremely high precision over long time spans.

Mm/submm observations of symbiotic binary stars

, 2002
We present and discuss mm/submm observations of quiescent S-type symbiotic systems, and compare them with popular models proposed to account for their radio emission. We find that the M giant mass-loss rates derived from our observations are systematically higher than those reported for single M giants.

Symbiotic Eclipsing Binary Star CI Cyg. The Cold Component Variability [PDF]

International Astronomical Union Colloquium, 1988
AbstractIt has been shown that the cold component of CI Cyg eclipsing binary system is a variable star. The amplitude of its light variations is close to with the time interval of 40–60 days.This star being the red giant M4 can be attributed as SR type variability. The light variations is caused by its temperature variations.

Suspected symbiotic stars [PDF]

, 2022
During 1987 we were engaged in a program of observation of planetary nebulae and symbiotic stars. The program included a group of five objects classified as suspected symbiotic stars: CD-3608436, Sa3-43, 1 Th4-4, V3804 Sgr and He2-104.

New Symbiotic Stars or Candidates in LAMOST Low-resolution Spectra

The Astrophysical Journal
Symbiotic stars are among the most important binary systems for studying binary star interactions and Type Ia supernova progenitors. Based on the unique observational characteristics of symbiotic stars—strong H I and He I emission lines, giant spectral ...

Thermodynamics and Kinetics in Host Design for Dendrite‐Free Zinc Metal Anodes

Advanced Science, EarlyView.
This review comprehensively summarizes recent advances in host design strategies for high‐performance zinc metal anodes, and deeply elucidates their thermodynamic and kinetic design principles from the perspective of surface modification, interface engineering, and spatial confinement.
