	研究興趣與成果
Updated on September 3, 2006 目前正進行的研究領域有： (1) 星震學(Asteroseismology) 星震學為天文物理中新興的領域。許多種類的恆星被發現會震盪，利用觀測恆星表面的震波，可研究其恆星內部的結構與演化。間斷的觀測數據會在頻譜上產生假訊號，造成振盪模式的頻率及其它參數的測量誤差。為了準確地測量震波模式的頻率及其它參數，我們必須長時間且連續地觀測恆星的震盪。 (2) 地暉(Earthshine) 此一研究係利用天文觀測，間接來研究地球平均溫度的變化。地暉為月球暗面的亮度，其來源為照射到地球的太陽光，部份被反射至月球的暗面。因此地暉的強度與地球的平均反射率(global albedo)成正比。而地球的平均反射率影響地球的平均溫度。長期觀測地暉的變化可瞭解地球平均溫度的變化。
