The Crucial Role Of Surface Magnetic Fields For Stellar Dynamos: Epsilon Eridani, 61 Cygni A, and the Sun
Cool main-sequence stars, such as the Sun, have magnetic fields which are generated by an internal dynamo mechanism. In the Sun, the dynamo mechanism produces a balance between the amounts […]

An Application Of A solar-type Dynamo Model For Epsilon Eridani
During the last decade, the relation between activity cycle periods with stellar parameters has received special attention. The construction of reliable registries of activity reveals that solar type stars exhibit […]
