Spin down of the core rotation in red giants
, 2012 The space mission Kepler provides us with long and uninterrupted photometric time series of red giants. We are now able to probe the rotational behaviour in their deep interiors using the observations of mixed modes.

Toward a Self-consistent Hydrodynamical Model of the Solar Tachocline
The Astrophysical JournalThe solar tachocline is a thin internal boundary layer in the Sun located between the differentially rotating convection zone and the uniformly rotating region of the radiative interior beneath. E. A. Spiegel & J. P.

Stellar evolution with rotation [PDF]
Astronomy & Astrophysics, 2002 The anisotropies of the mass loss by stellar winds, which lead to asymmetric nebulae, influence the loss of angular momentum. Polar enhanced mass loss is embarking less angular momentum than isotropic mass loss, while equatorial mass loss is removing more angular momentum.

Intrinsic Ambipolarity and Rotation in Stellarators [PDF]
Physical Review Letters, 2008 It is shown that collisional plasma transport is intrinsically ambipolar only in quasiaxisymmetric or quasihelically symmetric magnetic configurations. Only in such fields can the plasma rotate freely, and then only in the direction of quasisymmetry. In a non-quasi-symmetric magnetic field, the average radial electric field is determined by parallel ...

Basroparib inhibits YAP‐driven cancers by stabilizing angiomotin
Molecular Oncology, EarlyView.Basroparib, a selective tankyrase inhibitor, suppresses Wnt signaling and attenuates YAP‐driven oncogenic programs by stabilizing angiomotin. It promotes AMOT–YAP complex formation, enforces cytoplasmic YAP sequestration, inhibits YAP/TEAD transcription, and sensitizes YAP‐active cancers, including KRAS‐mutant colorectal cancer, to MEK inhibition.

The Astronomical JournalFor solar-type stars, spots and their associated magnetic regions induce radial velocity perturbations through the Doppler rotation signal and the suppression of convective blueshift, collectively known as rotation modulation.

Living with a Red Dwarf: X-Ray, UV, and Ca ii Activity–Age Relationships of M Dwarfs
The Astrophysical Journal, 2023 The vast majority of stars in the nearby stellar neighborhood are M dwarfs. Their low masses and luminosities result in slow rates of nuclear evolution and minimal changes to the stars’ observable properties, even along astronomical timescales.

Studies on stellar rotation [PDF]
Astronomy & Astrophysics, 2003 We have computed new values of the gravity-darkening exponents β 1 (GDE) incorporating the interior-atmosphere coupling by combining our method developed previously and the properties of modern atmosphere models. The mass range where this coupling is applied is extended in the present work from 0.08 to 40 M O ..

Stellar yields of rotating first stars [PDF]
AIP Conference Proceedings, 2014 Metal poor stars provide valuable information about nucleosynthesis of the early universe. Interestingly, three known hyper metal-poor stars showing extremely low iron abundance of [Fe/H] < −5 similarly have some peculiarity in their abundance patterns, i.e., they show enhancement of intermediate mass elements such as C, N, O, Na, and Mg.
