Abstract: We calculated the populations of core-helium-burning (CHeB) stars and found that secondary red-clump (SRC) stars can form a SRC peak in the distributions of the frequency of maximum seismic amplitude (ν max ) and mean large-frequency separation (Δν) of CHeB stars when metallicity Z≥ 0.02.

We present multi-band results for GRB071010B based on Swift, Suzaku, and ground-based optical observations. This burst is an ideal target to evaluate the robustness of the E src peak − E iso and E src peak − E γ relations, whose studies have been in

2009年10月30日 · We present multi-band results for GRB071010B based on \Swift, \Suzaku, and ground-based optical observations. This burst is an ideal target to evaluate the robustness of the and relations, whose studies have been in stagnation due to the lack of the combined estimation of and long term optical monitoring.

截断后得到的信号通常是非周期信号，所以FFT结果就变成了连续的谱线，周期信号的频率-幅值不再是一条垂直的直线，而是一条曲线，同时幅值下降，泄露到曲线其他频率点，即我们常说的频谱泄露。 而窗函数一个周期函数，窗函数与截断信号相乘后，会变成比较接近周期函数的波形 (实际上就是利用窗函数进行调制)。 加窗后的信号进行FFT后，得到的频谱曲线会更窄，趋向于垂直直线。 因此对频谱泄露有一定改善。 2.知道为什么要加窗后，我们再来根据实际情况来选择我们 …

Our multi-wavelength analysis reveals that GRB071010B follows E src peak - E iso but violates the E src peak - E γ and E iso - E src peak - t src jet at more than the 3σ level. We present multi-band results for GRB071010B based on Swift, Suzaku, and ground-based optical observations.

This study presents multi-wavelength observational results for energetic GRB 100414A with GeV photons. The prompt spectral fitting using Suzaku/WAM data yielded spectral peak energies of E src peak of 1458.7 +132.6 - 106.6 keV and E iso of 34.5 +2.0 - 1.8 × 10 52 erg with z = 1.368.
