Turbulent friction in convective regions stars and planets is one of the key physical mechanisms that drive dissipation kinetic energy tidal flows their interiors evolution systems. This acts both on equilibrium/non-wave like tide inertial waves these layers. It thus necessary to obtain a robust prescription for this friction. In current state-of-the-art, it modeled by turbulent eddy-viscosity coefficient, based mixing-length theory, applied velocities tides. However, none prescriptions take...

Extended MS turn-offs are features commonly found in the colour-magnitude diagrams of young and intermediate age (less than about 2 Gyr) massive star clusters, where turn-off is broader can be explained by photometric uncertainties, crowding, or binarity. Rotation suspected to cause this feature, accumulating fast rotating stars, strongly affected gravity darkening rotation-induced mixing, near turn-off. This scenario successfully reproduces tight relation between actual extent luminosity...

The early pre-main sequence phase during which they are still likely surrounded by an accretion disk represents a puzzling stage of the rotational evolution solar-mass stars. While accreting and contracting do not seem to spin-up substantially. It is usually assumed that magnetospheric star-disk interaction tends maintain stellar rotation period constant (disklocking), but this hypothesis has never been thoroughly verified. Our aim investigate impact mechanism on spin phases. We devise model...

Classical T Tauri stars (CTTS) accrete material from their discs through magnetospheres. The geometry of the accretion flow strongly depends on magnetic obliquity, i.e., angle between rotational and axes. We aim at deriving distribution obliquities in a sample 10 CTTSs. For this, we monitored radial velocity variations HeI$λ$5876 line these stars' spectra along cycle. HeI is produced shock, close to pole. When axes are not aligned, this modulated by stellar rotation. amplitude modulation...

Abstract Planets in close-in orbits interact magnetically and tidally with their host stars. These interactions lead to a net torque that makes planets migrate inward or outward depending on orbital distance. We systematically compare the strength of magnetic tidal torques for typical observed star–planet systems (T-Tauri hot Jupiter, M-dwarf Earth-like planet, K star Jupiter) based state-of-the-art scaling laws. find characteristics system, effects can dominate. For very planets, we both...

The surface angular velocity evolution of low-mass stars is now globally understood and the main physical mechanisms involved in it are observationally quite constrained. Additionally, recent observations showed anomalies rotation period distribution open clusters sequence early K-type that cannot be reproduced by current momentum model. In this work, we study parameter space star-planet system's configurations to investigate if including tidal interaction models could reproduce these...

Tidal interaction governs the redistribution of angular momentum in close binary stars and planetary systems determines evolution towards possible equilibrium state. Turbulent friction acting on tide convective envelope low-mass is known to have a strong impact this exchange binaries. Moreover, theoretical modelling recent literature as well presented paper suggests that dissipation dynamical tide, constituted tidal inertial waves propagating envelope, weak compared during red-giant phase....

Age estimation techniques such as gyrochronology and magnetochronology can't be applied to stars that exchanged angular momentum with their close environment. This is especially true for massive close-in planetary companion (with a periods of few days or less), which could have been strongly impacted the rotational evolution host star, along stellar evolution, through star-planet tidal interaction. We showed interaction planet its star can modify surface rotation rate this latter, in most...

Various studies shown that dissipation tides either body very sensitive to its structure dynamics, like differential rotation which exists outer convective enveloppe solar-like stars giant gaseous planets. In particular, waves may strongly interact with zonal flows at so-called corotation resonances, where wave's Doppler-shifted...

The presence of a massive close-in planet with an orbital period few days or less around low-mass star can possibly results in strong variation the properties central star. Indeed, star-planet tidal interactions generate exchanges angular momentum that spin-up. This effect could then lead to gyrochronological ages biased towards younger ages.
