This page intentionally left blank THE EMI SSI ON- LI NE UNI VERSE Emission lines provide a powerful tool for studying the physical properties and chemical compositions of astroph. The broad-band X-ray spectrum is fitted with a dominant emission temperature of just kT= keV along with significant wind absorption. The broad-band wind absorption and the line profiles provide two independent measurements of the wind mass-loss rate: + × M ☉ yr-1 and + × M ☉ yr-1, respectively. This is. Rotational periods increase with stellar age, as expected for a magnetic braking scenario. Without exception, all stars with H α emission originating in a CM are (1) rapid rotators, (2) strongly magnetic, and (3) young, with the latter property consistent with the observation that magnetic fields and rotation both decrease over time.
