X-rays and hard UV radiation From the First Galaxies: Ionization Bubbles and 21 cm Observations
stars: Population III. galaxies: high-redshift. (galaxies:) quasars: general. galaxies: star formation. cosmology: theory. (cosmology:) dark ages, reionization, rst stars
2011/10/9
The first stars and quasars are known sources of hard ionizing radiation in the first billion years of the Universe. We examine the joint effects of X-rays and hard UV radiation from such first-light ...
Helicity and dynamo action in magnetized stellar radiation zones
magnetohydrodynamics (MHD) – instabilities – stars: magnetic fi elds – stars: interiors
2011/10/8
Helicity and \alpha effect driven by the nonaxisymmetric Tayler instability of toroidal magnetic fields in stellar radiation zones are computed. In the linear approximation a purely toroidal field alw...
Radiation-driven winds of hot luminous stars. XVI. Expanding atmospheres of massive and very massive stars and the evolution of dense stellar clusters
Radiation mechanisms: general – Methods: numerical – Radiative transfer – early Universe – Stars: early-type – mass- loss – stellar winds – very massive stars – stellar evolution
2011/9/27
Context: Starbursts, and particularly their high-mass stars, play an essential role in the evolution of galaxies. The winds of massive stars not only significantly influence their surroundings, but th...

INTERACTION BETWEEN VARIABLE SOLAR UV RADIATION AND TROPOSPHERIC CIRCULATIONS AS A POSSIBLE CAUSE OF FIVE YEAR OSCILLATION IN EARTH ROTATION
VARIABLE SOLAR UV RADIATION TROPOSPHERIC CIRCULATIONS EARTH ROTATION
2009/3/16
It is shown that Five Year Oscillation in Earth rotation is possibly
caused by variable solar UV radiation and a corresponding perturbation mechanism
is suggested.
Reviving a calculation made by Eddington in the 1920s, and using the most recent and comprehensive databases available on stars and galaxies, including more than 2,500,000 stars and around 20,000 gala...
