Investigating Gaia EDR3 parallax systematics using asteroseismology of Cool Giant Stars observed by Kepler, K2, and TESS II. Deciphering Gaia parallax systematics using red clump stars

Saniya Khan, Richard I. Anderson, Andrea Miglio +2

We analyse Gaia EDR3 parallax systematics as a function of magnitude and sky location using a recently published catalogue of 12,500 asteroseismic red-giant star distances. We sele…

The combined effects of vertical and horizontal shear instabilities

Pascale Garaud, Saniya Khan, Justin M. Brown

Shear instabilities can be the source of significant amounts of turbulent mixing in stellar radiative zones. Past attempts at modeling their effects (either theoretically or using…

The evolution of the Milky Way's thin disc radial metallicity gradient with K2 asteroseismic ages

Emma Willett, Andrea Miglio, J. Ted Mackereth +8

The radial metallicity distribution of the Milky Way's disc is an important observational constraint for models of the formation and evolution of our Galaxy. It informs our underst…

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…

Investigating Gaia EDR3 parallax systematics using asteroseismology of Cool Giant Stars observed by Kepler, K2, and TESS I. Asteroseismic distances to 12,500 red-giant stars

Saniya Khan, Andrea Miglio, Emma Willett +10

Gaia EDR3 has provided unprecedented data that generate a lot of interest in the astrophysical community, despite the fact that systematics affect the reported parallaxes at the le…
