A Maia-type candidate was misclassified: V424 Cep is an eclipsing β Cep-type pulsator in a triple system
Schmutz, W.; Koenigsberger, G.; Richer, M. G. +2 more
Context. V424 Cephei is an eclipsing binary system that has been classified as a Maia variable candidate. These objects are pulsators that apparently lie outside the theoretical instability strips. Aims. We determine the properties of V424 Cep and identify the nature of the pulsating variable. Methods. We analyzed photometric data obtained over th…

Context. The synergy between different detection methods is a key asset in exoplanetology that allows the precise characterization of detected exoplanets and robust constraints even in the case of a non-detection. The interplay between imaging, radial velocities and astrometry has recently produced significant advancements in exoplanetary science.…
