We investigate the effect of the magnetic fields of M dwarf (dM) stars on potentially habitable Earth-like planets. These fields can reduce the size of planetary magnetospheres to such an extent that a significant fraction of the planet's atmosphere may be exposed to erosion by the stellar ...

Magnetic fields on other planets Additional resources Earth's magnetic field — also known as the geomagnetic field — is generated in our planet's interior and extends out into space, creating a region known as the magnetosphere. Without the magnetic field, life on Earth as we know it ...
An artist’s concept of a super-Earth in the habitable zone of a star smaller and cooler than the sun. Such large planets could have long-lasting magma oceans that generate magnetic fields capable of protecting incipient life. The graphic was created to model Kepler-62f, one of many exoplane...
“If there was a magnetic field on this moon that we’ve considered geologically torpid for so long, it might mean something for global magnetic fields on other planets,” saysGeorgiana Kramerat the Lunar and Planetary Institute in Texas. ...

Understanding properties of stellar magnetic fields in these stars finds a broad application in astrophysics, including theory of stellar dynamos and environment conditions around planets that may be orbiting these stars. Most stars with convective envelopes follow a rotation–activity relationship where ...

But magnetic fields that span the galaxy are almost too large to comprehend, and yet they likely have a role in the formation of stars and planets. "Until now, all observations of magnetic fields within the Milky Way led to a very limited model that...
