Insights into Bode`s Law
... In 1687, Newton wrote in the Book of Principia that masses have gravitational fields which cause bodies to attract each other with a force proportional to the product of their masses but inversely proportional to the square of the distance between them. However, since the planets have much smaller m ...

Determining the mass loss limit for close

The thermal mass loss of atomic hydrogen is calculated by modifying the energy-limited equation with a realistic heating efficiency, a radius-scaling law and a mass loss enhancement factor of the Roche lobe. The model takes into account the temporal evolution of the stellar XUV flux, by app ...

The High Eccentricity of the Planet Around 16 Cyg B

Companions with masses smaller than about 5 Jupiter masses have circular orbits while the more massive companions have eccentric orbits. The new planet, w ...
