摘要

近年来,我们发起并参与了许多研究非径向脉动天体的运动。我们的观测设备是约翰山大学天文台1.0米望远镜,配备了高效、极其稳定的梯队光谱仪,是光谱模式识别的理想选择。我们目前的兴趣包括δ Scuti恒星运动和研究γ Dor恒星的非径向脉动的计划。我们正在研究这些目标的几种不同的线轮廓分析和光谱模式识别方法。提出了该方案的概况,并附有具体的例子。

Coordinated observational campaigns for non-radially pulsating objects
In recent years we have initiated and contributed to a number of campaigns to study nonradially pulsating objects. Our observing facility is the Mt John University Observatory 1.0 m telescope equipped with a high-efficiency and extremely stable echelle spectrograph, ideal for spectroscopic mode identification. Our current interests include δ Scuti star campaigns and a programme to study the non-radial pulsations in γ Dor stars. We are investigating several different methods of line profile analysis and spectroscopic mode identification of these targets. An overview of the programme, with specific examples, is presented.
