Evolution of Massive Main-sequence Stars in Rapid Population Synthesis. I. Framework and Implementation
Adam Brček, Ryosuke Hirai, Ilya Mandel +1
Stars spend most of their lifetime on the main sequence (MS), where hydrogen burning establishes the internal chemical structure that governs the subsequent evolution. In massive s…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
Rapid stellar and binary population synthesis with COMPAS: methods paper II
Ilya Mandel, Jeff Riley, Adam Boesky +13
The COMPAS public rapid binary population synthesis code has undergone a number of key improvements since the original COMPAS methods paper (Team COMPAS: Riley et al., 2022) was pu…
Common envelopes in massive stars III. The obstructive role of radiation transport in envelope ejection
Mike Y. M. Lau, Ryosuke Hirai, Daniel J. Price +2
We present 3D radiation hydrodynamics simulations of common-envelope (CE) evolution involving a 12 solar mass red supergiant donor and a 3 solar mass companion. Existing 3D simulat…
Common envelopes at StanFest
Ilya Mandel, Ryosuke Hirai, Lewis Picker
We describe some of our group's recent work on common envelopes. Our goal is to understand the onset and outcomes of dynamically unstable mass transfer, including the properties of…
Evolution of the Convective Core Mass during the Main Sequence
Minori Shikauchi, Ryosuke Hirai, Ilya Mandel
We construct a semi-analytical model that describes the convective core mass evolution of massive stars experiencing mass loss during the main-sequence stage. We first conduct a su…
