. We show that the inclusion of special relativistic corrections in the revised OPAL and MHD equations of state has a significant impact on the helioseismic determination of the solar age. Models with relativistic corrections included lead to a reduction of about 0 . 05 − 0 . 08 Gyr with respect to those obtained with the old OPAL or MHD EOS. Our best-fit value is t seis = (4 . 57 ± 0 . 11) Gyr which is in remarkably good agreement with the meteoritic value for the solar age. We argue that the…

Continuous Habitable Zones: Using Bayesian Methods to Prioritize Characterization of Potentially Habitable Worlds

The number of potentially habitable planets continues to increase, but we lack the time and resources to characterize all of them. With ∼30 known potentially habitable planets and an ever-growing

Keeping It Cool: Much Orbit Migration, yet Little Heating, in the Galactic Disk

A star in the Milky Way’s disk can now be at a Galactocentric radius quite distant from its birth radius for two reasons: either its orbit has become eccentric through radial heating, which increases

Space expansion or dark energy are usually used to explain the fact that our universe is expanding at accelerating speeds. However, calculations show that the sun’s total gravitational forces towards

A calibration of the Rossby number from asteroseismology

Stellar activity and rotation are tightly related in a dynamo process. Our understanding of this mechanism is mainly limited by our capability of inferring the properties of stellar turbulent

A New Helioseismic Constraint on a Cosmic-time Variation of G

The best available estimate of 8640 days of low-ℓ BiSON data is used to constrain the evolution of Newton’s constant over cosmic time. The effect of different chemical compositions and the impact of

Dust trajectory simulations around the Sun, Vega, and Fomalhaut

Context. Vega and Fomalhaut display a thermal emission brightness that could possibly arise from hot dust near the stars, an inner extension of their planetary debris disks. An idea has been

Work from Light

After some background information on our star, the sun, the theory of radiation is explained briefly. One alternative derivation of the Stefan–Boltzmann law is presented here and obtained by means of
