Figure 1: A pre-main sequence Hertzsprung-Russell diagram showing the positions of W601 ( red square) and OI 201 ( green diamond). The CESAM PMS evolutionary tracks ( black full line), the zero-age main sequence (ZAMS) ( dot-dashed line), and the birthline ( blue dashed line) are also shown. |

Figure 2:
Upper frame: LSD I ( bottom), V ( upper) and N ( middle) profiles of W601. Full black line: 10/08, red-dashed line: 6/03 14:28, green dot-dot-dot-dashed line: 9/03. The mean error bars are plotted next to each profile. Lower frame: the broad, variable He I
of W601, observed on 6/03 ( full-black line) and 9/03 ( red-dashed line). The green long-dashed-line is a TLUSTY/SYNSPEC synthetic profile computed for a solar He abundance. |

Figure 3:
Upper frame: LSD I ( bottom), V ( upper) and N ( middle) profiles of OI 201. Full black line: 4/03, red-dashed line: 5/03 , blue dot-dashed line: 6/03, and green dot-dot-dot-dashed line: 9/03. The mean error bars are plotted next to each profile. Lower frame: the sharp, nonvariable He I
of OI 201, observed on 4/03 ( full-black line) and 9/03 ( red-dashed line). The green long-dashed-line is a TLUSTY/SYNSPEC synthetic profile computed for a solar He abundance. |
