First detection of an ultra-fast outflow (v≈0.07c) in a quiescent galaxy quenched ~9 Gyr ago, suggesting AGN winds can maintain quiescence independent of global star formation.
XRISM observations show the core of Abell 2199 is kinematically coherent with low turbulence, where turbulent heating may offset ~20% of radiative cooling losses.
A quench-pressure parameterisation with two free parameters recovers unbiased C/O and [M/H] from synthetic JWST spectra with vertical mixing, and tentatively detects quenching and photochemical H2S depletion in HD 189733b NIRCam data.
XRISM kinematics measurements in A3571 find low uniform velocity dispersion whose implied turbulent heating offsets cooling, with sloshing as a major contributor.
Barnard's Star planets have masses 0.19-0.84 M_earth, are tidally locked, unlikely to retain primary atmospheres, and possess mantles rich in ferropericlase with less than half Earth's water capacity and radiogenic heating.
Overview of methods and recent developments for deriving s- and r-process components of the proto-solar composition.
