    Title: Mars as a Nearby Exoplanetary Laboratory: Solar Wind Interaction, Atmospheric Loss, and Prebiotic Chemistry

    Abstract:
    Mars has always represented a vital target from the standpoint of planetary science, especially on account of its past, and perhaps even its current, biological potential. In particular, ancient Mars (∼ 4 Ga) has attracted a great deal of attention because it may have possessed aqueous environments with water-rock interactions, minerals, biogenic elements, suitable energy sources for prebiotic chemistry, and possibly oceans; all of these factors could have...

    Chaotic Dynamical Tides in Eccentric Gas Giants

    High-eccentricity migration is an important channel for the formation of hot Jupiters (HJs). In particular, Lidov–Kozai (LK) oscillations of orbital eccentricity/inclination induced by a distant planetary or stellar companion, combined with tidal friction, have been shown to produce HJs on Gyr time-scales. We re-examine this scenario with the inclusion of chaotic dynamical tides. When the planet’s orbit is in a high-eccentricity phase, the tidal force from the star excites oscillatory f-modes and i-modes in the planet. For sufficiently...

    Panning for gold with things that go bang in the night

    Abstract: Electromagnetic follow-up observations of the gravitational wave-detected binary neutron star merger (NSM) GW1701817 suggested that material ejected from the accretion disk formed in the merger underwent a robust r-process nucleosynthesis, producing heavy elements like Au, Pt, and Eu. These observations seemed to answer a long-standing question about the origin of the heaviest elements in the Universe. However, the conditions that characterize the disks formed in NSMs are also found in other systems,...
