Binary central stars of planetary nebulae [PDF]

open access: yesarXiv, 2006
This paper reviews our knowledge on binary central stars of planetary nebulae and presents some personal opinions regarding their evolution. Three types of interactions are distinguished: type I, where the binary companion induces the mass loss; type II, where it shapes the mass loss but does not enhance it; type III, where a wide orbit causes the ...

Electrodynamics and Dissipation in the Binary Magnetosphere of Premerger Neutron Stars

open access: yesThe Astrophysical Journal Letters
We investigate the energy release in the interacting magnetospheres of binary neutron stars (BNSs) with global 3D force-free electrodynamics simulations.

Exploring the Variability of Three Be Stars with TESS Observations

open access: yesUniverse
Be stars are rapidly rotating B-type stars surrounded by circumstellar disks formed from self-ejected material. Understanding the mechanisms driving mass ejection and disk formation, known as the Be phenomenon, requires a detailed investigation of their ...

Expansion of Accreting Main-sequence Stars during Rapid Mass Transfer

open access: yesThe Astrophysical Journal Letters
Accreting main-sequence stars expand significantly when the mass accretion timescale is much shorter than their thermal timescales. This occurs during mass transfer from an evolved giant star onto a main-sequence companion in a binary system and is an ...
