Asymmetrically Distributed Kelvin‐Helmholtz Instability at Venusian Magnetosphere

Maodong Yan, Jiuhou Lei, N. Terada, Binzheng Zhang et autres

Abstract The asymmetric distribution of Kelvin‐Helmholtz (KH) instability at Venusian ionopause is investigated using a multifluid model. Results show that KH instability distributes asymmetrically, preferentially developing in the −E (anti‐parallel to the interplanetary electric field) hemisphere. In the magnetosheath, solar wind H …

Effects of stellar XUV spectra on atmospheric escape from a Mars-like planet orbiting inactive low-mass stars

Shotaro Sakai, Akifumi Nakayama, K. Seki, N. Terada et autres

ABSTRACT The influence of stellar extreme ultraviolet (XUV) spectral shape on ion escape from Mars-like planets is investigated using a multispecies single-fluid magnetohydrodynamic model coupled with thermospheric profiles derived from a one-dimensional model under various XUV conditions. Target stars include the Sun, …

Unusually strong electronic correlation and field-induced ordered phase in YbCo$_2$

J. Valenta, N. Tsujii, F. Honda, H. Sakurai et autres

We report the first study of electrical resistivity, magnetization, and specific heat on YbCo$_2$. The measurements on a single-phased sample of YbCo$_2$ bring no evidence of magnetic ordering down to 0.3 K in a zero magnetic field. The manifestations of low Kondo …
