With the availability of large-scale surveys like Kepler and TESS, there is a pressing need for automated methods to classify light curves according to known classes of variable stars. We introduce a new algorithm for classifying light curves that co

Publikováno v: Monthly Notices of the Royal Astronomical Society

We study the $\delta$ Scuti -- red giant binary KIC9773821, the first double-pulsator binary of its kind. It was observed by \textit{Kepler} during its four-year mission. Our aims are to ascertain whether the system is bound, rather than a chance ali

Gaia-derived luminosities of Kepler A/F stars and the pulsator fraction across the delta Scuti instability strip

Autor: Daniel R. Hey, Timothy Van Reeth, Timothy R. Bedding, Simon J. Murphy

Publikováno v: Murphy, S J, Hey, D, Van Reeth, T & Bedding, T R 2019, ' Gaia-derived luminosities of Kepler A/F stars and the pulsator fraction across the δ Scuti instability strip ', Monthly Notices of the Royal Astronomical Society, vol. 485, no. 2, pp. 2380-2400 . https://doi.org/10.1093/mnras/stz590

We study the fraction of stars in and around the {\delta} Scuti instability strip that are pulsating, using {\em Gaia} DR2 parallaxes to derive precise luminosities. We classify a sample of over 15,000 {\em Kepler} A and F stars into {\delta} Sct and

We present the first data release of the Kepler Smear Campaign, using collateral 'smear' data obtained in the Kepler four-year mission to reconstruct light curves of 102 stars too bright to have been otherwise targeted. We describe the pipeline devel
