The relatively warm temperatures required on early Earth and Mars have been difficult to account for via warming from greenhouse gases. We tested whether this problem can be resolved for both Earth and Mars by a young Sun that is brighter than predicted by the standard solar model (SSM). We computed high-precision solar evolutionary models with slightly increased initial masses of Mi = 1.01-1.07 M☉; for each mass, we considered three different mass-loss scenarios. We then tested whether these… 

Assessing the Massive Young Sun Hypothesis to Solve the Warm Young Earth Puzzle

A moderately massive young Sun has been proposed to resolve the so-called faint young Sun paradox. We calculate the time evolution of the solar mass that would be required by this hypothesis using a

The Faint Young Sun Problem Revisited

Earth and Mars should have been frozen worlds in their early history because of lower solar luminosity but were not, which challenges our understanding of early atmospheres and surface conditions

THE SOLAR ENERGETIC BALANCE REVISITED BY YOUNG SOLAR ANALOGS, HELIOSEISMOLOGY, AND NEUTRINOS

The energetic balance of the standard solar model (SSM) results from equilibrium between nuclear energy production, energy transfer, and photospheric emission. In this Letter, we give an order of

Planetary influence on the young Sun's evolution: the solar neutrino probe

Recent observations of solar twin stars with planetary syst ems like the Sun, have uncovered that these present a peculiar surface chemical composition . This is believed to be related to the

Faint Young Sun, Planetary Paleoclimates and Varying Fundamental Constants

The effect of a cosmic time variation of the gravitational constant on the solar luminosity evolution is studied. It is demonstrated that a varying gravitational constant can substantially affect the

Helioseismology provides a powerful tool to explore the deep interior of the Sun. Measurements of solar interior quantities are provided with unprecedented accuracy: for example, the adiabatic sound

Helioseismological Implications of Recent Solar Abundance Determinations

We show that standard solar models are in good agreement with the helioseismologically determined sound speed and density as a function of solar radius, the depth of the convective zone, and the

The Faint Young Sun Paradox: An observational test of an alternative solar model

The authors' observations of pi 01 UMa, a 300 million year-old solar-mass star, place an upper limit on the mass loss rate of 4-5 x 10(-11) M(solar) yr-1, which casts doubt on the alternative model as a solution to the faint young Sun paradox, particularly for Mars.
