Post-merger rotational evolution of magnetised single hot subdwarfs results in slow rotation due to magnetic braking
Facundo D. Moyano, Zhengwei Liu, Zhanwen Han +3
Single hot subdwarfs are believed to form through mergers of helium-core white dwarfs, which can lead to large-scale magnetic fields generated during the merger, and may be observa…
On the origin of the rotation of massive stars
André Oliva, Facundo D. Moyano, Luca Sciarini +3
We explore the origin of the rotation rates of massive stars. Contrary to their low-mass siblings, most massive stars do not have detectable magnetic fields, so that star-disk inte…
Asteroseismic rotation rates of hot subdwarf B stars hint at transient accretion from leftover common envelope matter
Facundo D. Moyano, Hongwei Ge, Zhanwen Han +6
Asteroseismology enabled measuring the rotation rate in the deep stellar interiors of stars across several evolutionary phases, advancing the theory of angular momentum transport i…
The intermediate neutron capture process. VI. Proton ingestion and i-process in rotating magnetic asymptotic giant branch stars
A. Choplin, L. Siess, S. Goriely +2
The intermediate neutron-capture process (i-process) can occur during proton ingestion events (PIEs), which may take place in the early evolutionary phases of asymptotic giant bran…
Impact of the Tayler magnetic instability on the surface abundance of boron in massive stars
L. Asatiani, P. Eggenberger, M. Marchand +3
Context: The surface abundances of massive stars show evidence of internal mixing, while asteroseismic data suggest that efficient angular momentum (AM) transport occurs in stellar…
Grids of stellar models with rotation VIII: Models from 1.7 to 500 at metallicity
Yves Sibony, Kendall G. Shepherd, Norhasliza Yusof +12
Grids of stellar evolution models with rotation using the Geneva stellar evolution code (Genec) have been published for a wide range of metallicities. We introduce the last remaini…
Angular momentum transport near convective-core boundaries of Gamma Doradus stars
Facundo Moyano, Patrick Eggenberger, Sébastien Salmon
Recent asteroseismic studies have revealed that the convective core of Doradus stars rotates faster than their radiative interior. We study the development of differential rota…
Impact of different approaches for computing rotating stellar models I. The solar metallicity case
Devesh Nandal, Georges Meynet, Sylvia Ekström +6
The physics of stellar rotation plays a crucial role in the evolution of stars, their final fate and the properties of compact remnants. Diverse approaches have been adopted to inc…
Rotation in stellar interiors: General formulation and an asteroseismic-calibrated transport by the Tayler instability
P. Eggenberger, F. D. Moyano, J. W. den Hartogh
Context: Asteroseismic measurements of the internal rotation of evolved stars indicate that at least one unknown efficient angular momentum (AM) transport mechanism is needed in st…
Angular momentum transport by magnetic fields in main sequence stars with Gamma Doradus pulsators
F. D. Moyano, P. Eggenberger, S. J. A. J. Salmon +2
Context. Asteroseismic studies showed that cores of post main-sequence stars rotate slower than theoretically predicted by stellar models with purely hydrodynamical transport proce…
Asteroseismology of evolved stars to constrain the internal transport of angular momentum. VI. Testing a parametric formulation for the azimuthal magneto-rotational instability
F. D. Moyano, P. Eggenberger, B. Mosser +1
Asteroseismic measurements of the internal rotation rate in evolved stars pointed out to a lack of angular momentum (AM) transport in stellar evolution models. Several physical pro…
Spinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?
Jamie Tayar, Facundo D. Moyano, Melinda Soares-Furtado +15
In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and intermediate-mass stars, the…
Backtracing the internal rotation history of the Cep star HD 129929
Sébastien Salmon, Facundo Moyano, Patrick Eggenberger +2
HD 129929 is a slowly-rotating Cephei pulsator with a rich spectrum of detected oscillations, including two rotational multiplets. The asteroseismic interpretation revealed the…

F. D. Moyano, P. Eggenberger, G. Meynet +4
Thanks to asteroseismology, constraints on the core rotation rate are available for hundreds of low- and intermediate-mass stars in evolved phases. Current physical processes teste…
The magneto-rotational instability in massive stars
A. Griffiths, G. Meynet, P. Eggenberger +2
The interaction between weak magnetic fields and rotation can lead to instabilities that transport angular momentum (AM) and chemical elements affecting the evolution of massive st…
Asteroseismology of Cephei stars: The stellar inferences tested in hare and hound exercises
Sébastien Salmon, Patrick Eggenberger, Josefina Montalbán +5
The Cephei pulsators are massive main-sequence stars, presenting low radial-order modes. These modes probe in particular the chemical gradient at the edge of the convective cor…

Simón Díaz-García, Facundo D. Moyano, Sébastien Comerón +3
We investigate the spatial distribution of star formation (SF) within bars of nearby disk galaxies (inclination ) from the SG survey. We use archival GALEX far- a…
