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.   Asteroseismic Analyses of Slowly Pulsating B Star KIC 8324482: Ultraweak Element Mixing beyond the Central Convective Core 期刊论文  OAI收割 ASTROPHYSICAL JOURNAL, 2020, 卷号: 899, 期号: 1, 页码: 17 作者:  Wu T(吴涛);  Li Y(李焱);  Deng, Zhen-min;  Lin GF(林桂芳);  Song, Han-feng   |  收藏  |  浏览/下载：31/0  |  提交时间：2020/09/28 Asteroseismology  Stellar interiors  Stellar oscillations  Stellar structures  Fundamental parameters of stars  Stellar rotation  Stellar properties  B stars   A Pre-main-sequence gamma Dor-delta Sct Hybrid with Extremely Slow Internal Rotation in a Short-period Eclipsing Binary KIC 9850387 Revealed by Asteroseismology 期刊论文  OAI收割 The Astrophysical Journal, 2020, 卷号: 895, 期号: 2, 页码: 12 作者:  Zhang, Xiaobin;  Chen XH(陈兴浩);  Zhang, Haotong;  Fu, Jianning;  Li Y(李焱)   |  收藏  |  浏览/下载：39/0  |  提交时间：2020/07/20 Eclipsing binary stars  Pre-main sequence stars  Stellar oscillations  Stellar rotation  Stellar interiors   KIC 10736223: An Algol-type Eclipsing Binary That Has Just Undergone the Rapid Mass-transfer Stage 期刊论文  OAI收割 The Astrophysical Journal, 2020, 卷号: 895, 期号: 2, 页码: 13 作者:  Chen XH(陈兴浩);  Zhang, Xiaobin;  Li Y(李焱);  Chen HL(陈海亮);  Luo, Changqing   |  收藏  |  浏览/下载：41/0  |  提交时间：2020/07/20 Asteroseismology  Stellar oscillations  Delta Scuti variable stars  Eclipsing binary stars   KIC 10736223: An Algol-type Eclipsing Binary That Has Just Undergone the Rapid Mass-transfer Stage 期刊论文  OAI收割 The Astrophysical Journal, 2020, 卷号: 895, 期号: 2 作者:  Chen,Xinghao;  Zhang,Xiaobin;  Li,Yan;  Chen,Hailiang;  Luo,Changqing   |  收藏  |  浏览/下载：22/0  |  提交时间：2021/12/06 Asteroseismology  Stellar oscillations  Delta Scuti variable stars  Eclipsing binary stars   A Pre-main-sequence γ Dor-δ Sct Hybrid with Extremely Slow Internal Rotation in a Short-period Eclipsing Binary KIC 9850387 Revealed by Asteroseismology 期刊论文  OAI收割 The Astrophysical Journal, 2020, 卷号: 895, 期号: 2 作者:  Zhang,Xiaobin;  Chen,Xinghao;  Zhang,Haotong;  Fu,Jianning;  Li,Yan   |  收藏  |  浏览/下载：28/0  |  提交时间：2021/12/06 Eclipsing binary stars  Pre-main sequence stars  Stellar oscillations  Stellar rotation  Stellar interiors   Orbital evolution of a planet with tidal dissipation in a restricted three-body system 期刊论文  OAI收割 RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2019, 卷号: 19, 期号: 9 作者:  Wang WenLei;  Xu XueQing;  Liao XinHao   |  收藏  |  浏览/下载：15/0  |  提交时间：2021/12/06 HOT JUPITERS  GIANT PLANETS  STELLAR SPIN  ECCENTRICITY  SATELLITES  FRICTION  EXOPLANETS  TIDES  PERTURBATIONS  OSCILLATIONS  astrometry and celestial mechanics: celestial mechanics  planet-star interactions  planets and satellites: dynamical evolution and stability   The YNEV stellar evolution and oscillation code 期刊论文  OAI收割 RESEARCH IN ASTRONOMY AND ASTROPHYSICS, 2015, 卷号: 15, 期号: 4, 页码: 549-568 作者:  Zhang QS(张钱生) 收藏  |  浏览/下载：36/0  |  提交时间：2016/04/07 stars  stellar structure  stellar evolution  stellar oscillations   Integration and commissioning of the China SONG Telescope Tracking System 会议论文  OAI收割 Montréal, Quebec, Canada, 2014-6-22 作者:   收藏  |  浏览/下载：35/0  |  提交时间：2015/03/12 China SONG telescope  direct drive  full automatic control  Telescope pointing system  SONG (Stellar Oscillations Network Group)
