We present a simple diagnostic that can be used to constrain the location of the differential rotation in red giants with measured mixed mode rotational splittings. Specifically, in red giants with radii $\sim 4R_\odot$, the splittings of p-dominated modes (sound wave dominated) relative to those of g-dominated modes (internal gravity wave dominated) are sensitive to how much of the differential rotation resides in the outer convection zone versus the radiative interior of the red giant.

Asteroseismic sensitivity to internal rotation along the red-giant branch

Transport of angular momentum in stellar interiors is currently not well understood. Asteroseismology can provide us with estimates of internal rotation of stars and thereby advances our

Convective differential rotation in stars and planets – II. Observational and numerical tests

Differential rotation is central to a great many mysteries in stars and planets. In Part I we predicted the order of magnitude and scaling of the differential rotation in both hydrodynamic and

The Rotational Shear Layer inside the Early Red-giant Star KIC 4448777

We present the asteroseismic study of the early red-giant star KIC 4448777, complementing and integrating a previous work, aimed at characterizing the dynamics of its interior by analyzing the

Slowing the spins of stellar cores

The angular momentum (AM) evolution of stellar interiors, along with the resulting rotation rates of stellar remnants, remains poorly understood. Asteroseismic measurements of red giant stars

Mode Mixing and Rotational Splittings. I. Near-degeneracy Effects Revisited

Rotation is typically assumed to induce strictly symmetric rotational splitting into the rotational multiplets of pure p- and g-modes. However, for evolved stars exhibiting mixed modes, avoided

Convective differential rotation in stars and planets – I. Theory

We derive the scaling of differential rotation in both slowly and rapidly rotating convection zones using order of magnitude methods. Our calculations apply across stars and fluid planets and all

Testing Angular Momentum Transport and Wind Loss in Intermediate-mass Core-helium Burning Stars

Stars between 2 and 3 M☉ rotate rapidly on the main sequence, and their rotation rates in the core-helium burning (secondary-clump) phase can therefore be used to test models of angular momentum loss

Asteroseismology of evolved stars to constrain the internal transport of angular momentum

Context. The internal characteristics of stars, such as their core rotation rates, are obtained via asteroseismic observations. A comparison of core rotation rates found in this way with core

Rotation and Magnetism of Massive Stellar Cores

The internal rotation and magnetism of massive stars are considered in response to (i) the inward pumping of angular momentum through deep and slowly rotating convective layers, and (ii) the winding

Differential rotation in convective envelopes: constraints from eclipsing binaries

Over time, tides synchronize the rotation periods of stars in a binary system to the orbital period. However, if the star exhibits differential rotation, then only a portion of it can rotate at the



Spin down of the core rotation in red giants

Fast core rotation in red-giant stars as revealed by gravity-dominated mixed modes

An increasing rotation rate from the surface of the star to the stellar core in the interiors of red giants is reported using the rotational frequency splitting of recently detected ‘mixed modes’, which confirms the theoretical prediction of a steep gradient in the rotation profile towards the deep stellar interior.
