On the origin of sinusoidal brightness variations in F to O-type stars through radial velocities
E. Šipková, M. Skarka, M. Vaňko +3
Stellar variability may originate from various phenomena such as binarity, pulsations, or rotation. These mechanisms can induce flux variations of similar magnitudes, shapes, and p…
