Asteroseismology and interferometry of the F7V spectroscopic binary Draconis A in the TESS CVZ

Jonatan Rudrasingam, Mikkel N. Lund, Frank Grundahl +26

We present a detailed analysis of the asteroseismic main-sequence benchmark star Dra A in the TESS northern CVZ. We aim to derive stellar mass and radius from asteroseismic mod…
