Most population I Wolf-Rayet (WR) stars are the He-rich descendants of the most massive stars (M_i = 25 - 100 M_sun). Evidence has been accumulating over the years that among all pop I WR stars, those of the relatively cool, N-rich subtype "WN8" are among the most peculiar: 1. They tend to be runaways, with large space velocity and/or avoid clusters. 2. Unlike their equally luminous WN6,7 cousins, only a very small number of WN8 stars are known to belong to a close binary with an OB companion…

The Evolution of Compact Binary Star Systems
The formation and evolution of compact binary stars consisting of white dwarfs, neutron stars, and black holes are reviewed, including their role as progenitors of cosmologically-important thermonuclear SN Ia and AM CVn-stars, which are thought to be the best verification binary GW sources for future low-frequency GW space interferometers.
The formation of double compact objects as gravitational wave sources
The advanced LIGO/Virgo have detected gravitational-wave signals of merging double black holes and merging double neutron stars, opening a new window for astronomers to study the universe.The coming
