Young et al. — «With high equilibrium temperatures and tidally locked rotation, ultra-hot Jupiters (UHJs) are unique laboratories within which to probe extreme atmospheric physics and chemistry. In this paper, we present high-resolution dayside…»

19:08 <raptop> okay, that's a good title: https://arxiv.org/abs/2407.11187

19:08 <galois> [arXiv] “The future looks dark: improving high contrast imaging with hyper-parameter optimization for data-driven predictive wavefront control” J. Fowler, Rebecca Jensen-Clem, Maaike A. M. van Kooten et al. — «The direct imaging and characterization of exoplanets requires extreme adaptive optics (XAO), achieving exquisite wavefront correction (upwards of 90$\%$ Strehl) over a narrow field of view (a few arcseconds). For these…»

19:22 <galois> [arXiv] “Epsilon Sagittarii: An Extreme Rapid Rotator with a Decretion Disk” Jeremy Bailey, Fiona Lewis, Ian D. Howarth et al. — «We report high-precision multi-wavelength linear-polarization observations of the bright B9 (or A0) star $\epsilon$ Sagittarii. The polarization shows the distinctive wavelength dependence expected for a rapidly rotating star. Analysis of the polarization data reveals an angular rotation rate $\omega$…»
