recommendations! Published in 2025 at "Astrophysics and Space Science"

DOI: 10.1007/s10509-025-04508-6

Abstract: Stellar rotation has long been recognized as important to the evolution of stars, by virtue of the chemical mixing it can induce and how it interacts with binary mass transfer. Binary interaction and rapid rotation… read more here.

DOI: 10.1051/0004-6361/201834409

Abstract: Young massive stars regulate the physical conditions, ionization, and fate of their natal molecular cloud and surroundings. It is important to find tracers that help quantifying the stellar feedback processes that take place at different… read more here.

DOI: 10.1088/1674-4527/adb47e

Abstract: The subsurface convective zones (CZs) of massive stars significantly influence many of their key characteristics. Previous studies have paid little attention to the impact of rotation on the subsurface CZ, so we aim to investigate… read more here.

DOI: 10.1093/mnras/staa533

Abstract: The convection that takes place in the innermost shells of massive stars plays an important role in the formation of core-collapse supernova explosions. Upon encountering the supernova shock, additional turbulence is generated, amplifying the explosion.… read more here.

DOI: 10.1093/mnras/staa554

Abstract: A very small fraction of (runaway) massive stars have masses exceeding $60$-$70\, \rm M_{\odot}$ and are predicted to evolve as Luminous-Blue-Variable and Wolf-Rayet stars before ending their lives as core-collapse supernovae. Our 2D axisymmetric hydrodynamical… read more here.

recommendations! Published in 2022 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stac538

Abstract: The evolution of massive stars is affected by a variety of physical processes including convection, rotation, mass loss and binary interaction. Because these processes modify the internal chemical abundance profiles in multiple ways simultaneously, it… read more here.

recommendations! Published in 2022 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stac986

Abstract: Massive stars exhibit a variety of instabilities, many of which are poorly understood. We explore instabilities induced by centrifugal forces and angular momentum transport in massive rotating stars. First, we derive and numerically solve linearized… read more here.

recommendations! Published in 2023 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stad1541

Abstract: Binarity and pulsations are two notable properties that frequently appear together in massive stars. To place constraints on how binarity affects stellar evolution, the exact parameters of massive stars in binary systems must be known.… read more here.

recommendations! Published in 2024 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stae2682

Abstract: Light emission in the first hours and days following core-collapse supernovae is dominated by the escape of photons from the expanding shock-heated envelope. In preceding papers, we provided a simple analytic description of the time-dependent… read more here.

recommendations! Published in 2025 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/staf1470

Abstract: The initial mass and metallicity of stars both have a strong impact on their fate. Stellar axial rotation also has a strong impact on the structure and evolution of massive stars. In this study, we… read more here.

DOI: 10.1093/mnras/staf1697

Abstract: Pulsation plays a vital role in the evolution of massive stars found in eclipsing binaries. Although massive stars are uncommon compared to their less-massive counterparts, the frequency and intrinsic characteristics of these stars in eclipsing… read more here.
