| dc.description.abstract | 我們使用X-ray與光學觀測找尋薔薇星雲中的恆星X射線源。從ROSAT的網路資料庫中，我們找出了47個X射線源。利用光學影像、光譜、與光度資料，我們定出這些源的光學特性，並決定它們是否為薔薇星雲的成員星。最後，我們一共發現5個金牛座T型星與兩個赫比格AeBe星。並發現一個O型星可能有鋰吸收線，這暗示可能有低質量的年輕伴星。 | zh_TW |
| dc.description.abstract | We have used X-ray and optical observations to find the stellar X-ray sources in the
Rosette Nebula star-forming region. From $ROSAT$ archival data, we totally found 47 point
X-ray sources. We invetigate the optical properties of the X-ray sources by optical images,
photometry, and sprctroscopy, which allow us to distinguish among member stars in the region
from field stars. Five T Tauri stars and 2 Herbig Ae/Be stars have been identified by this
study. One O type star has been detected to have a weak 6707A Li absorption line,
indicating a possible young low-mass compaion. | en_US |
