By performing MHD simulations, we investigate the mass loss of intermediate- and low-mass stars from MS to RGB phases. Alfvén waves, which are excited by the surface convections, travel outwardly and dissipate by nonlinear processes to accelerate and heat the stellar winds. We dynamically treat these processes in open magnetic field regions from the photospheres to ≃25 stellar radii. When the stars evolve to slightly blueward positions of the dividing line (Linsky & Haisch), the steady hot…

Abstract By performing global 1D MHD simulations, we investigate the heating and acceleration of solar and stellar winds in open magnetic field regions. Our simulation covers from photosphere to

Evolution of solar-type stellar wind

By extending our self-consistent MHD simulations for the solar wind, we study the evolution of stellar winds of solar-type stars from early main sequence stage to red giant phase. Young solar-type

Turbulence-driven Polar Winds from T Tauri Stars Energized by Magnetospheric Accretion

Pre-main-sequence stars are observed to be surrounded by both accretion flows and some kind of wind or jetlike outflow. Recent work by Matt and Pudritz has suggested that if classical T Tauri stars

Accretion-powered Stellar Winds. II. Numerical Solutions for Stellar Wind Torques

In order to explain the slow rotation observed in a large fraction of accreting pre-main-sequence stars (CTTSs), we explore the role of stellar winds in torquing down the stars. For this mechanism to

Abstract In this talk we introduce our recent results of global 1D MHD simulations for the acceleration of solar and stellar winds. We impose transverse photospheric motions corresponding to the

Saturation of Stellar Winds from Young Suns

We investigate mass losses via stellar winds from sun-like main sequence stars with a wide range of activity levels. We perform forward-type magnetohydrodynamical numerical experiments for Alfven

Disk Winds Driven by Magnetorotational Instability and Dispersal of Protoplanetary Disks

By performing local three-dimensional MHD simulations of stratified accretion disks, we investigate disk winds driven by MHD turbulence. Initially weak vertical magnetic fields are effectively

Atmospheric Heating and Wind Acceleration in Cool Evolved Stars

A chromosphere is a universal property of stars of spectral type later than ∼ F5. Evolved K and M giants and supergiants, including the ζ Aur binaries, show extended and highly turbulent

TESTING A PREDICTIVE THEORETICAL MODEL FOR THE MASS LOSS RATES OF COOL STARS

The basic mechanisms responsible for producing winds from cool, late-type stars are still largely unknown. We take inspiration from recent progress in understanding solar wind acceleration to develop

Alfvén Wave-driven Wind from RGB and AGB Stars

We develop a magnetohydrodynamical model of Alfvén wave-driven wind in open magnetic flux tubes piercing the stellar surface of red giant branch (RGB) and asymptotic giant branch (AGB) stars, and

Supersonic stellar winds and rapid mass loss in cool stars

Chromospheric pressures have recently been determined among a sample of cool stars by Kelch et al. Combining these with a minimum flux coronal model, we derive a supersonic transition locus (STL) in
