Mass loss from solar-type stars
Solar Physics, 1985Winds are directly detected from solar-type stars only when they are very young. At ages ~ 106 yr, these stars have mass loss rates ~ 106 times the mass flux of the present solar wind. Although these young T Tauri stars exhibit ultraviolet transition-region and X-ray coronal emission, the large particle densities of the massive winds lead to efficient ...

Particle transport in solar type stars
AIP Conference Proceedings, 1985The potential effects of three particle transport processes on solar evolution are discussed. Even though its effect is not very large, atomic diffusion should in principle be included in the standard solar model. It increases the neutrino flux. Turbulent diffusion could significantly reduce the neutrino flux.

Dynamo of the Sun and Solar-Type Stars
EAS Publications Series, 2009The objective of this paper is to give a review of solar and stellar activity, from the observationnal constraints to dynamo models. I first review solar observations and insist on the various scales. Then I describe the photospheric magnetic structures (from spots and plages to the magnetic network and internetwork magnetic fields) and the energetic ...

The Photometric Variability of Solar-Type Stars
Proceedings of the International Astronomical Union, 2015AbstractThe joint variability of chromospheric emission with the integrated flux in the Kepler visible band for the Sun as a star is examined. No correlation between our Ca II K line parameter and the Kepler passband is seen, suggesting that visible-band variability in solar-like stars is mostly independent of solar-like chromospheric activity. However,

Effective temperatures of solar type stars
Astronomical & Astrophysical Transactions, 2002For 29 stars of G0-G5 spectral types with color indices 0.60 \leq B\ndash V \le 0.68 and parallaxes obtained by Hipparcos satellite effective temperatures, angular diameters and radii are determined by means of the method of infrared fluxes (IRFM) on the basis of JHKLM photometry. Effective temperatures obtained by iterations in the process of combined

Lithium depletion in solar-type stars
2008The theme of this conference is, essentially, stars with surface convective zones. Most of the phenomena discussed here, such as chromospheric and coronal activity, or angular momentum loss, occur because these stars representing a broad range of temperature and mass have surface convection. But despite the fundamental importance of convection for what
