Presupernova Evolution in Massive Interacting Binaries
TLDR
In this paper, a Henyey-type stellar evolution code was modified to allow its application to binary stellar evolution calculations, making it possible to trace the effects of mass and angular momentum loss from the binary, as well as mass transfer within the binary system.Abstract:
The way in which binary interaction affects the presupernova evolution of massive close binaries and the resulting supernova explosions is investigated systematically by means of a Henyey-type stellar evolution code that was modified to allow its application to binary stellar evolution calculations. The code makes it possible to trace the effects of mass and angular momentum loss from the binary, as well as mass transfer within the binary system. It is found that a large number of binary scenarios can be distinguished, depending on the type of binary interaction and the evolutionary stage of the supernova progenitor at the time of the interaction. Monte Carlo simulations are performed to estimate the frequencies of the occurrence of various scenarios. It is found that, because of a previous binary interaction, 15-30 percent of all massive stars (with initial masses greater than about 8 solar masses) become helium stars, and another 5 percent of all massive stars end their lives as blue supergiants rather than as red supergiants.read more

TL;DR: More than 70% of all massive stars will exchange mass with a companion, leading to a binary merger in one-third of the cases, greatly exceed previous estimates and imply that binary interaction dominates the evolution of massive stars, with implications for populations ofmassive stars and their supernovae.

Progenitors of Core-Collapse Supernovae
TL;DR: In this article, the authors reviewed the recent progress in finding the progenitors of core-collapse supernovae and the physical mechanism of the explosion. But they did not discuss the physical mechanisms of the supernova explosion.

A Comprehensive Study of Binary Compact Objects as Gravitational Wave Sources: Evolutionary Channels, Rates, and Physical Properties
TL;DR: In this article, the authors use population synthesis methods to calculate the properties and coalescence rates of double compact object binaries: double neutron stars, black hole-neutron star systems, and double black holes.

TL;DR: In this paper, the authors present the current best physical understanding of common envelope evolution (CEE) and highlight areas of consensus and disagreement, and stress ideas which should point the way forward for progress in this important but long-standing and largely unconquered problem.
