TL;DR: In this article, the rotational splittings in red giants and scaling relations for rotation related to seismic and fundamental stellar parameters are derived using a dedicated method for automated measurements of rotational splitting in a large number of red giants, which leads to the conclusion that the mean core rotation significantly slows down during the red giant phase.

TL;DR: In this paper, the authors detect mixed modes (i.e., modes that behave both as g modes in the core and as p modes in an envelope) in the spectrum of the early red giant KIC 7341231, which was observed during one year with the Kepler spacecraft.

TL;DR: In this article, the rotational splittings and frequencies of the modes for six young Kepler red giants were extracted and a seismic modeling of these stars using the evolutionary codes Cesam2k and astec was performed.

TL;DR: In this article, a parametric fit to the pattern of the � = 1 mixed modes in red giants is reported, which is a powerful tool to identify gravity-dominated mixed modes, which are able to probe directly the helium core and the surrounding shell where hydrogen is burning.

TL;DR: In this article, the authors provided a theoretical basis for the scaling between the frequency of the maximum in the power spectrum (νmax) of solar-like oscillations and the cut-off frequency (νc).
