Chromospheric and coronal heating in an active region plage by dissipation of currents from braiding
Nature Astronomy, Published online: 15 April 2024; doi:10.1038/s41550-024-02241-8 Analysis of high-resolution observations of solar ‘plage’ regions (areas of high magnetic field) shows a correlation between coronal emission and the thermodynamic properties of the chromosphere below. Simulations suggest the same heating
Sputnik Planitia as an impactor remnant indicative of an ancient rocky mascon in an oceanless Pluto
Nature Astronomy, Published online: 15 April 2024; doi:10.1038/s41550-024-02248-1 Foreign material delivered as a giant impact can dominate large portions of icy dwarf planets, according to impact simulations. This scenario may explain the peculiar shape and location of the Sputnik Planitia
Innovative measurements of stellar mass loss
Nature Astronomy, Published online: 12 April 2024; doi:10.1038/s41550-024-02227-6 Analysis of archival XMM-Newton data yields measurements of stellar wind emission from three star systems, illustrating a direct method to determine the mass-loss rates of late-type main-sequence stars. ————— Free Secure Email

Identification of the weak-to-strong transition in Alfvénic turbulence from space plasma
Nature Astronomy, Published online: 12 April 2024; doi:10.1038/s41550-024-02249-0 Turbulence plays a key role in space and astrophysical plasmas. The study reports evidence of the weak-to-strong transition when Alfvénic turbulence cascades from large to small scales revealed from the Cluster observation
