Application of an electric field changes the transport and optical properties of samarium nickelate submerged in water, making it a suitable passive sensor of weak electric fields in salt water.
Mapping the three-dimensional trajectory of a Neptune-mass exoplanet across the disk of its cool star reveals that its orbit is nearly perpendicular to the stellar equator, implying the existence of a yet-undetected outer companion planet.
A weak magnetic field regulates magnetically gated accretion of gas from a companion star onto the white dwarf in the binary system MV Lyrae, previously labelled as a ‘non-magnetic’ system.
