Radial distribution of distant trans-Neptunian objects points to Sun's formation in a stellar cluster
Abstract The Scattered Disk Objects (SDOs) are a population of trans-Neptunian bodies with
semimajor axes 50< a≲ 1000 au and perihelion distances q≳ 30 au. The detached SDOs …

Survivability of amorphous ice in comets depends on the latent heat of crystallization of impure water ice
Comets are believed to have amorphous rather than crystalline ice at the epoch of their
accretion. Cometary ice contains some impurities that govern the latent heat of ice …

Self-consistent Conditions for 26Al Injection into a Protosolar Disk from a Nearby Supernova
The early solar system contained a short-lived radionuclide, 26 Al (its half-life time t 1/2= 0.7
Myr). The decay energy of 26 Al is thought to have controlled the thermal evolution of …
