Are the spin axes of stars randomly aligned within a cluster?
R. J. Jackson, R. D. Jeffries
We investigate to what extent the spin axes of stars in young open clusters are aligned. Assuming that the spin vectors lie uniformly within a conical section, with an opening half…
The radii of M-dwarfs in the young open cluster NGC 2516
R. J. Jackson, R. D. Jeffries, P. F. L. Maxted
Using a novel technique, which combines previously determined rotation periods with new spectroscopic determinations of projected rotation velocity, we have determined radii for fa…
Low-mass members of the young cluster IC 4665 and pre-main-sequence lithium depletion
R. D. Jeffries, R. J. Jackson, D. J. James +1
We have used fibre spectroscopy to establish cluster membership and examine pre-main-sequence (PMS) lithium depletion for low-mass stars (spectral types F to M) in the sparse young…
