The birth environment of the solar system
FC Adams - Annual Review of Astronomy and Astrophysics, 2010 - annualreviews.org
This review examines our current understanding of the possible birth environments of our
Solar System. Because most stars form within groups and clusters, the question becomes …

The Sun in time: activity and environment
M Güdel - Living Reviews in Solar Physics, 2007 - Springer
The Sun's magnetic activity has steadily declined during its main-sequence life. While the
solar photospheric luminosity was about 30% lower 4.6 Gyr ago when the Sun arrived on …

Planetesimal formation by gravitational instability
AN Youdin, FH Shu - The Astrophysical Journal, 2002 - iopscience.iop.org
We investigate the formation of planetesimals via the gravitational instability of solids that
have settled to the midplane of a circumstellar disk. Vertical shear between the gas and a …

Potassium isotope anomalies in meteorites inherited from the protosolar molecular cloud
Y Ku, SB Jacobsen - Science Advances, 2020 - science.org
Potassium (K) and other moderately volatile elements are depleted in many solar system
bodies relative to CI chondrites, which closely match the composition of the Sun. These …
