A Mini Atlas of H-Band Spectra of Southern Symbiotic Stars [PDF]
Galaxies, 2023 Symbiotic stars are interacting binary systems composed of an evolved star (generally a late-type red giant) and a degenerate or dwarf companion in orbit close enough for mass transfer to occur. Understanding the status of the late-type star is important

The Astronomical Journal, 2023 Accretion of mass onto a white dwarf (WD) in a binary system can lead to stellar explosions. If a WD accretes from stellar wind of a distant evolved giant in a symbiotic binary, it can undergo occasional outbursts in which it brightens by several ...

Comprehensive Analysis of a Symbiotic Candidate V503 Her
The Astronomical Journal, 2023 V503 Her was previously proposed as an eclipsing symbiotic candidate based on photometric behavior and spectroscopic appearance indicating the composite optical spectrum.

An XMM-Newton View of the Symbiotic Stars HM Sge, NQ Gem, and PU Vul
The Astrophysical Journal, 2023 We present the analysis of archival XMM-Newton observations of the symbiotic stars HM Sge, NQ Gem, and PU Vul. The EPIC-pn spectra hint at the presence of emission lines, which are further confirmed in the first-order RGS spectra of the three sources ...

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.

New Symbiotic Stars or Candidates in LAMOST Low-resolution Spectra
The Astrophysical JournalSymbiotic 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 ...

Exploring Mass Transfer Mechanisms in Symbiotic Systems
The Astrophysical JournalWe define two regimes of the parameter space of symbiotic systems based on the dominant mass transfer mechanism. A wide range of white dwarf (WD) mass, donor mass, and donor radius combinations are explored to determine the separation for each parameter ...
