Terrestrial planet formation. [PDF]
Proc Natl Acad Sci U S A, 2011 Advances in our understanding of terrestrial planet formation have come from a multidisciplinary approach. Studies of the ages and compositions of primitive meteorites with compositions similar to the Sun have helped to constrain the nature of the building blocks of planets.

Challenges in planet formation [PDF]
Journal of Geophysical Research E: Planets, 2016 AbstractOver the past two decades, large strides have been made in the field of planet formation. Yet fundamental questions remain. Here we review our state of understanding of five fundamental bottlenecks in planet formation. These are the following: (1) the structure and evolution of protoplanetary disks; (2) the growth of the first planetesimals; (3)

Impact Induced Oxidation and Its Implications for Early Mars Climate
Geophysical Research Letters, 2023 H2 in a CO2 atmosphere may serve as a potential solution to the early Mars climate paradox, but its unknown sources cast doubts on the proposed mechanism. Impact cratering is an energetic process that may modify the surface redox budget.

A tale of planet formation: from dust to planets [PDF]
Research in Astronomy and Astrophysics, 2020 Abstract The characterization of exoplanets and their birth protoplanetary disks has enormously advanced in the last decade. Benefitting from that, our global understanding of the planet formation processes has been substantially improved.

The Astrophysical Journal Letters, 2023 We present a U-corrected Pb–Pb age of 4566.19 ± 0.20 Ma (1.11 ± 0.26 Myr after t _0 ) for the moderately volatile element rich, andesitic meteorite Erg Chech 002 (EC002). Our Al–Mg isochron defines a ^26 Al/ ^27 Al initial ratio of (8.65 ± 0.09) × 10 ^−6

The Astrophysical Journal, 2023 In protostellar cores, sulfur species are effective probes for the energetic environments, such as shocked regions. With the majority of sulfur depleted on dust grains, sulfur-bearing molecules could be liberated back to gas phase by shocks associated ...

Simulations for Terrestrial Planets Formation [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractWe investigate the formation of terrestrial planets in the late stage of planetary formation using two-planet model. At that time, the protostar has formed for about 3 Myr and the gas disk has dissipated. In the model, the perturbations from Jupiter and Saturn are considered.
