Atmospheric carbon depletion as a tracer of water oceans and biomass on temperate terrestrial exoplanets

Kavli Affiliate: Sara Seager | First 5 Authors: Amaury H. M. J. Triaud, Julien de Wit, Frieder Klein, Martin Turbet, Benjamin V. Rackham | Summary: The conventional observables to identify a habitable or inhabited environment in exoplanets, such as an ocean glint or abundant atmospheric O$_2$, will be challenging to detect with present or upcoming […]

Quantum Hamiltonian Algorithms for Maximum Independent Sets

Kavli Affiliate: Frank Wilczek | First 5 Authors: Xianjue Zhao, Peiyun Ge, Hongye Yu, Li You, Frank Wilczek | Summary: We compare two quantum Hamiltonian algorithms that address the maximum independent set problem: one based on emergent non-abelian gauge matrix in adiabatic evolution of an energetically isolated manifold of states; and one based on designed […]

Masses, Revised Radii, and a Third Planet Candidate in the “Inverted” Planetary System Around TOI-1266

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Ryan Cloutier, Michael Greklek-McKeon, Serena Wurmser, Collin Cherubim, Erik Gillis | Summary: Is the population of close-in planets orbiting M dwarfs sculpted by thermally driven escape or is it a direct outcome of the planet formation process? A number of recent empirical results strongly suggest the latter. […]

Searching for strong gravitational lenses

Kavli Affiliate: Paul Schechter | First 5 Authors: Cameron Lemon, Frédéric Courbin, Anupreeta More, Paul Schechter, Raoul Cañameras | Summary: Strong gravitational lenses provide unique laboratories for cosmological and astrophysical investigations, but they must first be discovered – a task that can be met with significant contamination by other astrophysical objects and asterisms. Here we […]
