Mercury’s surprising density: What about magnets?
A new model explains Mercury’s major density with magnetism.
A new model explains Mercury’s major density with magnetism.
Strongly magnetized rocks on Mars are primarily concentrated in the southern hemisphere. This paper raises a serious objection to the hypothesis that localized dynamo action in the ancient martian core explains this puzzling observation.
The existence of a conducting layer near the core/mantle boundary has profound implications for the operation of a dynamo in rocky exoplanets and for our ability to detect exoplanetary magnetic fields.
