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.   Determining the size of the helium core of KIC 9970396 using asteroseismology: a red giant approaching the red giant bump 期刊论文  OAI收割 MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2020, 卷号: 494, 期号: 1, 页码: 511-528 作者:  Zhang XY(张昕旖);  Li Y(李焱);  Wu T(吴涛);  Su J(苏杰)   |  收藏  |  浏览/下载：25/0  |  提交时间：2020/06/22 stars: individual: KIC 9970396  stars: oscillations  stars: solar-type   Observations of a Quasi-periodic Pulsation in the Coronal Loop and Microwave Flux during a Solar Preflare Phase 期刊论文  OAI收割 ASTROPHYSICAL JOURNAL LETTERS, 2020, 卷号: 893, 期号: 1, 页码: 6 作者:  Li Dong;  Li Ying;  Lu Lei;  Zhang Qingmin;  Ning Zongjun   |  收藏  |  浏览/下载：13/0  |  提交时间：2021/12/06 Solar flares  Solar oscillations  Solar ultraviolet emission  Solar radio emission   Observations of a Quasi-periodic Pulsation in the Coronal Loop and Microwave Flux during a Solar Preflare Phase 期刊论文  OAI收割 ASTROPHYSICAL JOURNAL LETTERS, 2020, 卷号: 893, 期号: 1, 页码: 6 作者:  Li Dong;  Li Ying;  Lu Lei;  Zhang Qingmin;  Ning Zongjun   |  收藏  |  浏览/下载：10/0  |  提交时间：2021/12/06 Solar flares  Solar oscillations  Solar ultraviolet emission  Solar radio emission   Quasi-periodic Pulsation Detected in Ly alpha Emission During Solar Flares 期刊论文  OAI收割 ASTROPHYSICAL JOURNAL, 2020, 卷号: 893, 期号: 1, 页码: 11 作者:  Li, Dong;  Lu, Lei;  Ning, Zongjun;  Feng, Li;  Gan, Weiqun   |  收藏  |  浏览/下载：18/0  |  提交时间：2021/12/06 Solar flares  Solar oscillations  Solar chromosphere  Solar ultraviolet emission  Solar x-ray emission   Quasi-periodic Pulsations of Gamma-Ray Emissions from a Solar Flare on 2017 September 6 期刊论文  OAI收割 The Astrophysical Journal, 2020, 卷号: 888, 期号: 2 作者:  Li,D.;  Kolotkov,D.
