The other factor that arises from this is that CMEs, of all the various dangerous stellar eminations, appear to be most responsible for planetary atmospheric erosion so anything that mitigates their effect has got to be good in terms of planetary habitability and most of all in M dwarf systems where the «habitable zone» is close to the star and well within the region
of synchronous rotation.
Not exact matches
Since the moon spins on its axis at the same speed it revolves around Earth, what scientists call
synchronous rotation, you'll always have a good view
of home.
Most inner moons
of planets have
synchronous rotation, so their
synchronous orbits are, in practice, limited to their leading and trailing Lagrange points.
Planets in the habitable zone
of low - mass, cool stars are expected to be in
synchronous rotation, where one side
of the planet always faces the host star (the substellar point) and the other side experiences perpetual night (the anti-stellar point).
Furthermore, they are locked in a mutual
synchronous rotation while having an almost circular, no - eccentric orbit, which disfavor the formation
of any currently active geological processes on their surfaces or interiors.
The problem with planets orbiting M - dwarfs is that they are prone to fall into «
synchronous rotation» so that one side
of the planet always faces the star, while the other side remains in perpetual darkness.
Planets with such orbits are also more likely to have greater orbital eccentricity which if not too large can in turn can contribute to non
synchronous rotation such as 3:2 or even 2; 1 resonances, as seen in Mercury with an orbital eccentricity
of 0.2.
Synchronous rotation can occur as a result of tidal forces from gravitational interactions between two orbiting bodies (Earth's moon is an example of an object in synchronous rotation, so that we only ever see one side from t
Synchronous rotation can occur as a result
of tidal forces from gravitational interactions between two orbiting bodies (Earth's moon is an example
of an object in
synchronous rotation, so that we only ever see one side from t
synchronous rotation, so that we only ever see one side from the ground).
These observations also confirm that Titan's
rotation is in fact
synchronous like most
of Saturn's other moons.
Moreover, the star seems to be depleted in lithium because it has maintained comparably dynamo - induced, chromospheric activity resulting from a relatively fast,
synchronous (tidally - locked)
rotation with its companion and so it may have lost about 10 percent more
of its matter than would a single star
of its mass and age (Strobel et al, 1994).
