Jb. Rice et Kg. Strassmeier, DOPPLER IMAGING OF STELLAR SURFACE-STRUCTURE .2. THE WEAK-LINED T-TAURI STAR V410-TAURI, Astronomy and astrophysics, 316(1), 1996, pp. 164-172
We present a new Doppler image of the rapidly-rotating weak-lined T Ta
uri star V410 Tauri and compare this new map with one previously publi
shed from observations taken over a year earlier. We find cool spots a
t both equatorial latitudes and at high latitudes with the high latitu
de spots being cooler and showing greater area and having greater long
evity than the equatorial spots. A comparison of the two maps shows li
ttle relative change in the positions of the equatorial spots compared
to the spots at high latitude suggesting very little differential rot
ation and what there is appears to be in the same sense as the Sun. Gl
obal spot lifetime would appear to be on the order of the time interva
l between the two maps, that is about a year. There are several hot fe
atures evident supporting the claim for the existence of such features
based on our map of Nov. 1992.
