Patchy nightside clouds on ultra-hot Jupiters: General Circulation Model simulations with radiatively active cloud tracers

no code yet • 16 May 2022

In this work, we add to previous efforts by also considering the localized condensation of clouds in the atmospheres of ultra-hot Jupiters, their resulting transport by the atmospheric circulation, and the radiative feedback of clouds on the atmospheric dynamics.

Wide twin binaries are extremely eccentric: evidence of twin binary formation in circumbinary disks

no code yet • 11 May 2022

For the excess-twin population at 400-1000 AU, we infer a near-delta function excess of high-eccentricity system, with eccentricity $0. 95 \lesssim e \leq 1$.

Disruption of Saturn's ring particles by thermal stress

no code yet • 11 May 2022

We found that thermal stress can grind porous ring particles larger than 10-20 m, which explains the lack of particles larger than 10 m in Saturn's ring.
