Angular Momentum Transport via Internal Gravity Waves in Evolving Stars
Recent asteroseismic advances have allowed for direct measurements of the internal rotation rates of many sub-giant and red giant stars. Unlike the nearly rigidly rotating Sun, these evolved stars contain radiative cores that spin faster than their overlying convective envelopes, but slower than they would in the absence of internal angular momentum transport. We investigate the role of interna...
متن کاملAngular Momentum Transport by Gravity waves in the Solar Interior
We present self-consistent numerical simulations of the sun’s convection zone and radiative interior using a two-dimensional model of its equatorial plane. The background reference state is a one-dimensional solar structure model. Turbulent convection in the outer convection zone continually excites gravity waves which propagate throughout the stable radiative interior and deposit their angular...
متن کاملAngular Momentum Transport by Internal Gravity Waves I - Pop I Main Sequence Stars
We examine the generation of gravity waves by the surface convection zone of low-mass main sequence stars with solar metallicity. It is found that the total momentum luminosity in waves rises with stellar mass, up to the quasi-disappearance of the convection zone around 6500 K (corresponding to a mass of ∼1.4 M⊙ for solar metallicity) where the luminosity drastically drops. We calculate the net...
متن کاملAngular Momentum Transport by Internal Gravity Waves II - Pop II stars from the Li plateau to the horizontal branch
This paper is the second in a series where we examine the generation and filtering of internal gravity waves in stars and the consequences of wave induced transport of angular momentum at various stages of the stellar evolution. Here we concentrate on Pop II dwarf stars and we focus in particular on the differential properties of internal gravity waves as a function of the stellar mass. We show...
متن کاملEffects of Internal Gravity Waves on Energy Budgets and the Vertical Transport of Angular Momentum Over Mountainous Terrain
High-resolution pictures obtained with a h a n d h el d camera during the earth-orbiting photographic mission of the Apollo 9 spacecraft provided a unique opportunity to map the areal extent of gravity waves over the southwestern United States. The gravity waves were manifested in thin layers of middleand high-cloud patterns over the rugged terrain of Arizona, Colorado, and New Mexico. Zonal sh...
