Properties of at small opening angles in collisions with the ATLAS detector at TeV

ATLAS Collaboration

The fragmentation of high-energy gluons at small opening angles is largely unconstrained by present measurements. Gluon splitting to -quark pairs is a unique probe into the prop…

Instabilities in the Early Solar System due to a Self-gravitating Disk

Billy Quarles, Nathan Kaib

Modern studies of the early solar system routinely invoke the possibility of an orbital instability among the giant planets triggered by gravitational interactions between the plan…

The early instability scenario: terrestrial planet formation during the giant planet instability, and the effect of collisional fragmentation

Matthew S. Clement, Nathan A. Kaib, Sean N. Raymond +2

The solar system's dynamical state can be explained by an orbital instability among the giant planets. A recent model has proposed that the giant planet instability happened during…

Predicting the Extreme Ultraviolet Radiation Environment of Exoplanets Around Low-Mass Stars: the TRAPPIST-1 System

Sarah Peacock, Travis Barman, Evgenya L. Shkolnik +2

The high energy radiation environment around M dwarf stars strongly impacts the characteristics of close-in exoplanet atmospheres, but these wavelengths are difficult to observe du…

Ferromagnetic Mott State in Twisted Graphene Bilayers at the Magic Angle

Kangjun Seo, Valeri N. Kotov, Bruno Uchoa

We address the effective tight-binding Hamiltonian that describes the insulating Mott state of twisted graphene bilayers at a magic angle. In that configuration, twisted bilayers f…

Observations of SN 2017ein Reveal Shock Breakout Emission and A Massive Progenitor Star for a Type Ic Supernova

Danfeng Xiang, Xiaofeng Wang, Jun Mo +23

We present optical and ultraviolet observations of nearby type Ic supernova SN 2017ein as well as detailed analysis of its progenitor properties from both the early-time observatio…
