Asteroseismic modelling strategies in the PLATO era I. Mean density inversions and direct treatment of the seismic information
Jérôme Bétrisey, Gaël Buldgen, Daniel R. Reese +6
Asteroseismic modelling will be part of the pipeline of the PLATO mission and will play a key role in the mission precision requirements on stellar mass, radius and age. It is ther…
RUBIS: a simple tool for calculating the centrifugal deformation of stars and planets
Pierre S. Houdayer, Daniel R. Reese
We present RUBIS (Rotation code Using Barotropy conservation over Isopotential Surfaces), a fully Python-based centrifugal deformation program available at \url{https://github.com/…
Inversions of stellar structure from asteroseismic data
Gaël Buldgen, Jérôme Bétrisey, Ian W. Roxburgh +2
The advent of space-based photometry missions in the early 21st century enabled the application to asteroseismic data of advanced inference techniques until then restricted to the…
Properties of the ionisation glitch II. Seismic signature of the structural perturbation
Pierre S. Houdayer, Daniel R. Reese, Marie-Jo Goupil
In the present paper, we aim to constrain the properties of the ionisation region in a star from the oscillation frequency variation (a so-called glitch) caused by rapid structural…
The SAPP pipeline for the determination of stellar abundances and atmospheric parameters of stars in the core program of the PLATO mission
Matthew Raymond Gent, Maria Bergemann, Aldo Serenelli +25
We introduce the SAPP (Stellar Abundances and atmospheric Parameters Pipeline), the prototype of the code that will be used to determine parameters of stars observed within the cor…
Five young Scuti stars in the Pleiades seen with Kepler/K2
Simon J. Murphy, Timothy R. Bedding, Timothy R. White +4
We perform mode identification for five Scuti stars in the Pleiades star cluster, using custom light curves from K2 photometry. By creating échelle diagrams, we identify radial…
