The boundaries of Doppler imaging: Starspot patterns on M dwarfs
With the advent of 8-m class telescopes and model atmospheres incorporating molecular opacities a great deal of interest has been directed towards the previously unexplored cool, low mass stars. M dwarfs are obviously a ...
Further images of α Persei G dwarfs
We present two images of intermediate and low axial inclination G dwarfs (AP 149 and AP 193) in the young open cluster a Persei, and compare these with previous images of intermediate and high axial inclination objects in ...
Doppler images from dual-site observations of southern rapidly rotating stars - II. Starspot patterns and differential rotation on Speedy Mic
We have secured high spatial and temporal resolution spectra of the rapidly rotating K dwarf Speedy Mic (HD 197890) at two sites and a common epoch of observations. The 0.38-d axial rotation period and the V-band magnitude ...
