Abstract The surface rotation rates of young solar-type stars decrease rapidly with age from the end of the pre-main sequence though the early main sequence. This suggests that there is also an important change in the dynamos operating in these stars, which should be observable in their surface magnetic fields. Here we present early results in a study aimed at observing the evolution of these magnetic fields through this critical time period. We are observing stars in open clusters and stellar… 

The Effect of Magnetic Variability on Stellar Angular Momentum Loss. I. The Solar Wind Torque during Sunspot Cycles 23 and 24

The rotational evolution of cool stars is governed by magnetized stellar winds that slow the stellar rotation during their main sequence lifetimes. Magnetic variability is commonly observed in

Constraining the Angular Momentum-loss Rates of the Sun and Other Sun-like Stars

1st Supervisor: Prof. Sean P. Matt 2nd Supervisor: Prof. Matthew Browning Stellar rotation, convection, and magnetism are intricately linked in low-mass stars like the Sun. In their outer convective

Magnetism, dynamo action and the solar-stellar connection

Observations and theory of magnetism in the Sun and other stars are reviewed, with a partial focus on the “Solar-stellar connection”: ways in which studies of other stars have influenced the authors' understanding of theSun and vice versa.

Stellar Coronal and Wind Models: Impact on Exoplanets

Surface magnetism is believed to be the main driver of coronal heating and stellar wind acceleration. Coronae are believed to be formed by plasma confined in closed magnetic coronal loops of the

Ages for exoplanet host stars

Age is an important characteristic of a planetary system, but also one that is difficult to determine. Assuming that the host star and the planets are formed at the same time, the challenge is to

The rotation axis of the Sun is misaligned from the mean angular momentum plane of the solar system by about 6°. This obliquity significantly exceeds the ∼1°–2° distribution of inclinations among the

It is argued that studying exoplanetary systems could open up new avenues for progress to be made in the authors' understanding of the evolution of the solar wind, as well as implications of the evolved solar wind on the evolving Earth and other solar system planets.
