Influence of surface stressing on stellar coronae and winds [PDF]

, 2013
STFC funding has supported this research.The large-scale field of the Sun is well represented by its lowest energy (or potential) state. Recent observations, by comparison, reveal that many solar-type stars show large-scale surface magnetic fields that ...

M-dwarf stellar winds : the effects of realistic magnetic geometry on rotational evolution and planets [PDF]

, 2014
AAV acknowledges support from a Royal Astronomical Society Fellowship. JM acknowledges support from a fellowship of the Alexander von Humboldt foundation.We perform three-dimensional numerical simulations of stellar winds of early-M-dwarf stars.

Stellar Winds in A-Type Supergiants [PDF]

Symposium - International Astronomical Union, 1994
A-type supergiants are just at the boundary between the early type supergiants, with strong stellar winds driven by radiation pressure and the cool supergiants in which the origin of mass loss is the dissipation of mechanical energy. The mechanisms involved in the mass loss processes in A supergiants as a whole, are still uncertain.

Interactions between exoplanets and the winds of young stars

EPJ Web of Conferences, 2014
The topology of the magnetic field of young stars is important not only for the investigation of magnetospheric accretion, but also responsible in shaping the large-scale structure of stellar winds, which are crucial for regulating the rotation evolution

Dust Coagulation in Oxygen-rich Circumstellar Outflows

The Astrophysical Journal, 2023
We show that the inefficient growth of SiO molecules on (SiO) _x dust grains prolongs the period of maximum dust nucleation in circumstellar outflows resulting in a several orders-of-magnitude increase in the dust density near the star.

AGB Winds with Gas-Dust Drift in Stellar Evolution Codes

Universe, 2021
A significant fraction of new metals produced in stars enter the interstellar medium in the form of dust grains. Including dust and wind formation in stellar evolution models of late-stage low- and intermediate-mass stars provides a way to quantify their

Relativistic stellar jets: dynamics and non-thermal radiation

EPJ Web of Conferences, 2013
Relativistic stellar jets, produced in binary systems called microquasars, propagate through media with different spatial scales releasing their energy in the form of work and radiation from radio to gamma rays.

Observational evidences of stellar wind [PDF]

International Astronomical Union Colloquium, 1981
AbstractObservations mainly from the IUE Spectra of HD 152236 (Blla) have been used to provide support to the various aspects of the theory of stellar wind (SW) and its interaction with the interstellar medium (ISM). Lines arising from excited levels connected radiatively to the ground level tend to be more frequent and/or strong compared to those ...
