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 …

We review the origin and evolution of the atmospheres of Earth, Venus and Mars from the
time when their accreting bodies were released from the protoplanetary disk a few million …

This paper presents a reformulation of the submarine alkaline hydrothermal theory for the
emergence of life in response to recent experimental findings. The theory views life, like …

The detection of molecules on the coldest and outermost objects in our Solar System has
long been limited by the terrestrial atmosphere and sensitivity of the available …

In the past few years, several major space missions have been completed (eg, Deep Impact,
LCROSS, Chandrayaan-1, Stardust, Hayabusa), and a number of spacecraft are currently …

Meteorites, which are remnants of solar system formation, provide a direct glimpse into the
dynamics and evolution of a young stellar object (YSO), namely our Sun. Much of our …

We investigate the origin and loss of captured hydrogen envelopes from protoplanets having
masses in a range between 'sub-Earth'-like bodies of 0.1 M⊕ and 'super-Earths' with 5 M⊕ …

The Sun provides a critical benchmark for the general study of stellar structure and
evolution. Also, knowledge about the internal properties of the Sun is important for the …

The origin and evolution of planetary protoatmospheres in relation to the protoplanetary disk
is discussed. The initial atmospheres of planets can mainly be related via two formation …

The atmospheric noble gas isotope and elemental bulk ratios on Venus and Earth provide
important information on their origin and evolution. If the protoplanets grew to a certain mass …
