Abstract (from CDS):

Mixed modes seen in evolved stars carry information on their deeper layers that can place stringent constraints on their physics and on their global properties (mass, age, etc.). In this study, we present a method to identify and measure all oscillatory mode characteristics (frequency, height, width). Analyzing four subgiant stars, we present the first measure of the effect of the degree of mixture on the ℓ = 1 mixed mode characteristics. We also show that some stars have measurable ℓ = 2 mixed modes and discuss the interest of their measure to constrain the deeper layers of stars.
