Crystallinity versus mass-loss rate in asymptotic giant branch stars [PDF]

, 2001
Infrared Space Observatory (ISO) observations have shown that O-rich Asymptotic Giant Branch (AGB) stars exhibit crystalline silicate features in their spectra only if their mass-loss rate is higher than a certain threshold value.

Red Supergiant Mass Loss and Mass-Loss Rates

Galaxies
This review discusses the causes, nature, importance and observational evidence of mass loss by red supergiants. It arrives at the perception that mass loss finds its origin in the gravity which makes the star a star in the first place, and is a ...

Mass Loss [PDF]

Observational evidence for mass loss from cool stars is reviewed. Spectra line profiles are used for the derivation of mass-loss rates with the aid of the equation of continuity. This equation implies steady mass loss with spherical symmetry.

MBD analysis of flexible multibody system with mass loss

Nihon Kikai Gakkai ronbunshu, 2016
In this paper, we propose a formulation method for flexible multi-body systems with mass loss. The method derives the equation of motion using the velocity transformation method, in consideration of the shift of center-of-mass.

Orbital Migration Through Atmospheric Mass Loss

The Astronomical Journal
Atmospheric mass loss is thought to have strongly shaped the sample of close-in exoplanets. These atmospheres should be lost isotropically, leading to no net migration on the planetary orbit.

Phenotypic plasticity in mass loss during chick rearing in the European starling (Sturnus vulgaris) [PDF]

Ecology and Evolution
It has long been recognized that mass loss during breeding could be adaptive (e.g., by ameliorating the costs of increased parental activity). However, many studies still commonly interpret mass loss as evidence of “stress” or a cost of reproduction (i.e.

Modeling of the Wind/Disk Outflow from Be Stars II: Formation of the Keplerian Disk

Universe, 2022
Computer modeling of the outflow from Be stars is performed. In our approach, processes of turbulence excitation and turbulent viscosity are added to the conventional model of the radiation driven winds.

Modeling of the Wind/Disk Outflow from Be Stars

Universe, 2021
The objective of this work is to reproduce the formation of the fast polar wind and viscous disk outflow from Be stars in a unified physical picture. Numerical modeling of the plasma outflow from fast rotating stars was performed taking into account the ...
