Secular- and merger-built bulges in barred galaxies
Context. Historically, galaxy bulges were thought to be single-component objects at the center of galaxies. However, this picture is now questioned since...
Seismic analysis of HD 43587Aa, a solar-like oscillator in a multiple system
Context. The object HD 43587Aa is a G0V star observed during the 145-day LRa03 run of the COnvection, ROtation and planetary Transits space mission (CoRoT), for...
Seismic and spectroscopic characterization of the solar-like pulsating CoRoT target HD 49385
Context. The star HD 49385 is the first G-type solar-like pulsator observed in the seismology field of the space telescope CoRoT. The satellite collected 137...
Seismic constraints on the radial dependence of the internal rotation profiles of six Kepler subgiants and young red giants
Context. We still do not understand which physical mechanisms are responsible for the transport of angular momentum inside stars. The recent detection of mixed...
Seismic probing of the first dredge-up event through the eccentric red-giant and red-giant spectroscopic binary KIC 9163796. How different are red-giant stars with a mass ratio of 1.015?
Context. Binaries in double-lined spectroscopic systems (SB2) provide a homogeneous set of stars. Differences of parameters, such as age or initial conditions...
Seismology of delta Scuti stars in the Praesepe cluster. I. Ranges of unstable modes as predicted by linear analysis versus observations
We consider here a representative set of delta Scuti stars observed in the Praesepe cluster, thanks to recent efforts of multi-site networks. We show that the...
Seismology of delta Scuti stars in the Praesepe cluster. II. Identification of radial modes and their associated stellar parameters
An analysis based on a comparison between observations and stellar models has been carried out to identify radial modes of oscillations in several multi...
Self-supervised component separation for the extragalactic submillimetre sky
We use a new approach based on self-supervised deep learning networks originally applied to transparency separation in order to simultaneously extract the...
Sensitivity of helioseismic gravity modes to the dynamics of the solar core
Context: The dynamics of the solar core cannot be properly constrained through the analysis of acoustic oscillation modes. Gravity modes (g modes) are necessary...
