The period-luminosity relation for delta Scuti stars using Gaia DR2 parallaxes

Elham Ziaali, Timothy R. Bedding, Simon J. Murphy +2

We have examined the period-luminosity (P-L) relation for delta Scuti stars using Gaia DR2 parallaxes. We included 228 stars from the catalogue of Rodriguez et al. (2000), as well…

Period spacings of Doradus pulsators in the \textit{Kepler} field: Rossby and gravity modes in 82 stars

Gang Li, Timothy Van Reeth, Timothy R. Bedding +2

Rossby modes are the oscillations in a rotating fluid, whose restoring force is the Coriolis force. They provide an additional diagnostic to understand the rotation of stars, which…
