Doppler imaging of the T Tauri star HDE 283572.

JONCOUR I., BERTOUT C. and BOUVIER J.

Abstract (from CDS):

We present Doppler images of the surface temperature distribution of the rapidly rotating weak-emission line T Tauri star HDE 283572, as computed from the FeIλ6400A, FeIλ6393A, CaIλ6439A, and LiIλ6707A photospheric lines. This analysis reveals the presence of one large polar structure 1600K colder than the surrounding photosphere. We also find a possible rotational modulation of the Hα and CaII equivalent line widths that suggests the presence of large-scale chromospheric structures above the stellar surface.
