TL;DR: A large increase in organic material occurred during and after the event, with smaller changes in carbon dioxide relative to water, and a thermal map indicates a surface in equilibrium with sunlight.

TL;DR: The OGLE-2012-BLG-0358Lb system as discussed by the authors is a relatively tightly separated binary composed of a planetary-mass object with 1.9 ± 0.2 Jupiter masses orbiting a BD with a mass 0.022 M ☉.
Journal ArticleDOI
Simultaneous Triggered Collapse of the Presolar Dense Cloud Core and Injection of Short-Lived Radioisotopes by a Supernova Shock Wave
Alan P. Boss,Sergei I. Ipatov,Sandra A. Keiser,Elizabeth A. Myhill,Elizabeth A. Myhill,Harri A. T. Vanhala,Harri A. T. Vanhala +6 more
TL;DR: In this article, the authors show that a 20 km s−1 shock wave can indeed trigger the collapse of a 1 M cloud while simultaneously injecting shock wave isotopes into the collapsing cloud, provided that cooling by molecular species such as H2O, CO2, and H2 is included.

TL;DR: In this article, the authors show that a 20 km s?1 shock front can simultaneously trigger collapse of a 1 M? core and inject shock wave material, provided that cooling by molecular species such as H2O, CO, and H2 is included.
