dc.description.abstract | In this paper, the latitude distribution of star-spots is analysed for the rapidly rotating G dwarf He 699, An image has been reconstructed from data taken with the William Herschel Telescope on La Palma on 2000 October 8. The predominant magnetic field structure is a decentred polar spot at high latitude, with smaller low-latitude features also present. This result is verified by independent reconstructions using even- and odd-numbered spectra. This work confirms and extends that of Barnes et al.. and provides further evidence that there is a correlation between the presence of low-latitude features and the amplitude of the photometric light curve. It is also a further step in the search for activity cycles on young G dwarfs. | en |
