Asymptotic power spectra and visibilities of damped mixed modes
Jonas Müller, Quentin Coppée, Jordan Van Beeck +2
Recent observational studies of red giant stars have estimated the visibility of their mixed oscillation modes, which is a proxy of the average energy of these modes. Among other t…
The efficiency of mixed modes for angular momentum transport
Beatriz Bordadágua, Felix Ahlborn, Quentin Coppée +3
Core rotation rates of red-giant stars inferred from asteroseismic observations are substantially lower than predicted by current stellar models. This indicates the lack of an effi…
Power density spectra morphologies of seismically unresolved red-giant asteroseismic binaries
Jeong Yun Choi, Francisca Espinoza-Rojas, Quentin Coppée +1
Asteroseismic binaries are two oscillating stars detected in a single light curve. These systems provide robust constraints on stellar models from the combination of dynamical and…
Oscillations of red giant stars with magnetic damping in the core. I. Dissipation of mode energy in dipole-like magnetic fields
Jonas Müller, Quentin Coppée, Saskia Hekker
Strong magnetic fields in the core of red-giant branch stars are expected to suppress the amplitudes of the multipole modes. This occurs when the strength of the internal magnetic…
The radial modes of stars with suppressed dipole modes
Quentin Coppée, Jonas Müller, Michaël Bazot +1
The Kepler space mission provided high-quality light curves for more than 16 000 red giants. The global stellar oscillations extracted from these light curves carry information abo…
