The Central Star of NGC 2346 as a Clue to Binary Evolution through the Common Envelope Phase [PDF]

open access: yesThe Astrophysical Journal, 2019
Abstract We present an analysis of the binary central star of the planetary nebula NGC 2346 based on archival data from the International Ultraviolet Explorer, and new low- and high-resolution optical spectra (3700–7300 Å). By including in the spectral analysis the contribution of both stellar and nebular continuum, we reconciled long ...

The post-common-envelope, binary central star of the planetary nebula Hen 2-11 [PDF]

open access: yesAstronomy & Astrophysics, 2014
We present a detailed photometric study of the central star system of the planetary nebula Hen 2-11, selected for study because of its low-ionisation filaments and bipolar morphology - traits which have been strongly linked with central star binarity.

Post common envelope binaries from SDSS. IV, SDSS J121258.25–012310.1, a new eclipsing system [PDF]

open access: yes, 2009
From optical photometry we show that SDSS J121258.25–012310.1 is a new eclipsing, post common-envelope binary with an orbital period of 8.06 h and an eclipse length of 23 min.

A Not-so-compact Companion: Massive, Oversized White Dwarf in a Post-common-envelope Eclipsing Binary

open access: yesThe Astronomical Journal
We provide a detailed characterization of 2M07515777+1807352, a post-common-envelope eclipsing binary system with a 10.3-day, nearly (but not quite) circular orbit ( e = 0.02).

Advances in Solution‐Processed Textile Triboelectric Nanogenerators: Ink Formation, Processing Strategies, Applications, and Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Advanced ink systems for solution‐processed textile triboelectric nanogenerators are systematically summarized, spanning conductive, tribo‐negative, and tribo‐positive layers. By connecting ink chemistry, deposition methods, and device function, the present review reveals the key governing principles of solution development and highlights practical ...

Common Envelope Evolution

open access: yes, 2020
Common envelope evolution is the most important phase in the lives of many significant classes of binary stars. During a common envelope phase, the stars temporarily share the same outer layers, with the cores of both stars orbiting inside the same ...

Neuromorphic Electronics for Intelligence Everywhere: Emerging Devices, Flexible Platforms, and Scalable System Architectures

open access: yesAdvanced Materials, EarlyView.
The perspective presents an integrated view of neuromorphic technologies, from device physics to real‐time applicability, while highlighting the necessity of full‐stack co‐optimization. By outlining practical hardware‐level strategies to exploit device behavior and mitigate non‐idealities, it shows pathways for building efficient, scalable, and ...

Influence of Mass-transfer Stability on the Formation of Post-common-envelope Binaries

open access: yesThe Astrophysical Journal
Post-common-envelope binaries are the natural laboratories for constraining the physics of common-envelope evolution, which is one of the most uncertain phases in binary stellar evolution.

The Evolution of Population III and Extremely Metal-poor Binary Stars

open access: yesThe Astrophysical Journal, 2023
Numerical simulations have now shown that Population III (Pop III) stars can form in binaries and small clusters and that these stars can be in close proximity to each other.
