摘要

在这篇文章中，我们展示了我们在上普罗旺斯天文台使用AURELIE光谱仪获得的HIP 113790的高分辨率观测结果。通过对其基本参数的测定，我们确认该恒星位于δ Scuti不稳定带中。我们进一步报告了在约1.43小时的周期内检测到的快速线廓线变化。

Spectroscopy of HIP 113790 at the 5th OHP NEON summer school

In this contribution, we present the high–resolution observations we obtained for HIP 113790 at the Haute-Provence Observatory using the AURELIE spectrograph. By determing its fundamental parameters, we confirm that the star is located in the δ Scuti instability strip. We further report the detection of rapid line profile variations with a period of about 1.43 hours.
