TL;DR: In this paper, a detailed investigation of the three main binary evolution channels that can lead to the formation of sdB stars: the common-envelope (CE) ejection channel, the stable Roche lobe overflow (RLOF) channel, and the double helium white dwarfs (WDs) merger channel is presented.

TL;DR: In this article, the authors investigated the three main binary evolution channels that can lead to the formation of sdB stars: the common envelope (CE) ejection channel, the stable Roche lobe overflow (RLOF) channel and the double helium white dwarfs (WDs) merger channel.

TL;DR: In this paper, a new mechanism for the ejection of a common envelope in a massive binary, where the energy source is nuclear energy rather than orbital energy, was proposed, which can occur during the slow merger of a massive primary with a secondary of 1-3 M⊙ when the primary has already completed helium core burning.

TL;DR: In this paper, the authors present a new mechanism for the ejection of a common envelope in a massive binary, where the energy source is nuclear energy rather than orbital energy, which can occur during the slow merger of a massive primary with a secondary of 1-3 Msun when the primary has already completed helium core burning.

TL;DR: In this paper, the authors consider the case of dense, young stellar clusters where a 50-500 M central IMBH has formed through runaway growth of amassivestar.
