Igneous processes in the small bodies of the Solar System I. Asteroids and comets [PDF]
Summary: Igneous processes were quite widespread in the small bodies of the Solar System (SBSS) and were initially fueled by short-lived radioisotopes, the proto-Sun, impact heating, and differentiation heating.

Igneous meteorites suggest Aluminium-26 heterogeneity in the early Solar Nebula [PDF]
The short-lived radionuclide aluminium-26 (26Al) isotope is a major heat source for early planetary melting. The aluminium-26 – magnesium-26 (26Al-26Mg) decay system also serves as a high-resolution relative chronometer.

Igneous processes in the small bodies of the Solar System II: Small satellites and dwarf planets [PDF]
Summary: Evidence of hot and cold igneous processes has been reported in small satellites and dwarf planets of the Solar System. Olivine and pyroxenes were detected in the spectral bands of both small satellites and dwarf planets.

UV Monochromatic Imaging of the Protoplanetary Nebula Hen 3-1475 Using HST STIS [PDF]
Collimated outflows and jets play a critical role in shaping planetary nebulae (PNe), especially in the brief transition from a spherical AGB envelope to an aspherical PN, which is called the protoplanetary nebula (pPN) phase.

Converging lines of evidence show that protoplanetary disks are complex environments hosting spatial and temporal variability at multiple scales.

Using self-consistent models of turbulent particle growth in an evolving protoplanetary nebula of solar composition, we find that recently proposed local metallicity and Stokes number criteria necessary for the streaming instability to generate ...

The composition of the protosolar disk and the formation conditions for comets [PDF]
Conditions in the protosolar nebula have left their mark in the composition of cometary volatiles, thought to be some of the most pristine material in the solar system.

Accretion of dust by chondrules in a MHD-turbulent solar nebula [PDF]
(Abridged) Numerical magnetohydrodynamic (MHD) simulations of a turbulent solar nebula are used to study the growth of dust mantles swept up by chondrules. A small neighborhood of the solar nebula is represented by an orbiting patch of gas at a radius of

Dust photophoretic transport around a T Tauri star: Implications for comets composition [PDF]
There is a growing body of evidences for the presence of crystalline material in comets. These crystals are believed to have been annealed in the inner part of the proto-solar nebula, while comets should have been formed in the outer regions.
