Impact of a new H/He equation of state on the evolution of massive brown dwarfs
(EDP Sciences, 14 March 2023)We explored the impact of the latest equation of state (EOS) for dense hydrogen helium mixtures, which takes into account the interactions between hydrogen and helium species during the evolution of very low-mass stars and ... -
Evidence of radius inflation in radiative GCM models of WASP-76b due to the advection of potential temperature
(Oxford University Press / Royal Astronomical Society, 23 June 2023)Understanding the discrepancy between the radii of observed hot Jupiters and standard 'radiative-convective' models remains a hotly debated topic in the exoplanet community. One mechanism which has been proposed to bridge ... -
A Dual-Band Spaceplate: Contracting the Volume of Quasi-Optical Systems
(Institute of Electrical and Electronics Engineers (IEEE), 7 November 2023)A ‘spaceplate’ approximates the angular response of free space with a much thinner non-local metamaterial. They have the potential to significantly shrink the volume of optical and quasi-optical systems, by allowing ... -
Quantum quantile mechanics: Solving stochastic differential equations for generating time‐series
(Wiley, 7 August 2023)A quantum algorithm is proposed for sampling from a solution of stochastic differential equations (SDEs). Using differentiable quantum circuits (DQCs) with a feature map encoding of latent variables, the quantile function ... -
Refining the Stellar Parameters of τ Ceti: a Pole-on Solar Analog
(American Astronomical Society / IOP Publishing, 22 August 2023)To accurately characterize the planets a star may be hosting, stellar parameters must first be well determined. τ Ceti is a nearby solar analog and often a target for exoplanet searches. Uncertainties in the observed ...
