Is a 1D perturbative method sufficient for asteroseismic modelling of Cephei pulsators? Implications for measurements of rotation and internal magnetic fields
J. S. G. Mombarg, V. Vanlaer, S. B. Das +6
Asymmetries in the observed rotational splittings of a multiplet contain information about the star's rotation profile and internal magnetic field. However, to exploit this informa…
An Educational Guide for 2D Stellar Structure Calculations of Rapidly Rotating Stars using the ESTER code
Russel White, Jane Pratt, Michel Rieutord
The Evolution STEllaire en Rotation (ESTER) code is the first 2D stellar structure code to be made open-source and freely available to the astronomy and astrophysics community. An…
An improved asteroseismic age of the rapid rotator Altair from TESS data
Michel Rieutord, Daniel R. Reese, Joey S. G. Mombarg +1
Understanding the effects of rotation in stellar evolution is key to modelling early-type stars, half of which have equatorial velocities over 100 km/s. The nearby star Altair is a…
Spectroscopic detection of Altair's non-radial pulsations
M. Rieutord, P. Petit, D. Reese +4
Context: Rapid rotation is a common feature of early-type stars but which remains a challenge for the models. The understanding of its effect on stellar evolution is however impera…
Relation between trees of fragmenting granules and supergranulation evolution
Th. Roudier, J. M. Malherbe, M. Rieutord +1
Context: The determination of the underlying mechanisms of the magnetic elements diffusion over the solar surface is still a challenge. Understanding the formation and evolution of…
Comparison of solar horizontal velocity fields from SDO/HMI and Hinode data
Th. Roudier, M. Rieutord, V. Prat +7
The measurement of the Sun's surface motions with a high spatial and temporal resolution is still a challenge. We wish to validate horizontal velocity measurements all over the vis…
Quasi full-disk maps of solar horizontal velocities using SDO/HMI data
Th. Roudier, M. Rieutord, J. M. Malherbe +6
For the first time, the motion of granules (solar plasma on the surface on scales larger than 2.5 Mm) has been followed over the entire visible surface of the Sun, using SDO/HMI wh…
On the power spectrum of solar surface flows
M. Rieutord, T. Roudier, F. Rincon +4
The aim of this work is to give new observational constraints on solar surface flows by determining the horizontal scale dependence of the velocity and intensity fields, as represe…
