Abstract: Currently available models for magnetic braking of solar type stars, predict a braking that is too weak to explain the present-day spin of the Sun. Here we investigate whether having a more complex magnetic field topology or and increased intensity of magnetic field or mass-loss could provide a more physically reliable model. In addition, we show how the model can be used to explain the scarcity of hot Jupiters and brown dwarfs around G-type stars while they are present around their F-type counterparts.
