In this study, we present the investigation of nonstationary QPPs with multiple periods during the impulsive phase of a powerful flare on 2017 September 6, which were simultaneously measured by the Hard X-ray Modulation Telescope (Insight-HXMT), as well as the ground-based BLENSW. The multiple periods, detected by applying a wavelet transform and Lomb-Scargle periodogram to the detrended light curves, are found to be ~20-55 s in the Ly`and mid-ultraviolet Balmer continuum emissions during the flare impulsive phase. Similar QPPs with multiple periods are also found in the hard X-ray emission and low-frequency radio emission. Our observations suggest that the flare QPPs could be related to nonthermal electrons accelerated by the repeated energy release process, i.e., triggering of repetitive magnetic reconnection, while the multiple periods might be modulated by the sausage oscillation of hot plasma loops. For the multiperiodic pulsations, other generation mechanisms could not be completely ruled out.   G132-12: A one-mode ZZ Ceti star located at the blue edge of instability strip 期刊论文  OAI收割 NEW ASTRONOMY, 2019, 卷号: 73, 页码: 6 作者:  Chen, Jianxing;  Fu, Jianning;  Niu, Hubiao;  Li, Chun   |  收藏  |  浏览/下载：28/0  |  提交时间：2020/03/10 Photometry  White dwarfs  Oscillations (including pulsations) stars  Individual   High-precision Asteroseismology in a Slowly Pulsating B Star: HD 50230 期刊论文  OAI收割 ASTROPHYSICAL JOURNAL, 2019, 卷号: 881, 期号: 1, 页码: 15 作者:  Wu T(吴涛);  Li Y(李焱)   |  收藏  |  浏览/下载：60/0  |  提交时间：2019/09/23 asteroseismology  stars: fundamental parameters  stars: individual (HD 50230)  stars: interiors  stars: oscillations (including pulsations)   GD358: Three Decades of Observations for the In-depth Asteroseismology of a DBV Star 期刊论文  OAI收割 ASTROPHYSICAL JOURNAL, 2019, 卷号: 871, 期号: 1, 页码: 17 作者:  Bischoff-Kim, Agnes;  Provencal, J.
