Investigation of thermonuclear Ne(,)Na rate via resonant elastic scattering of Na+
L. Y. Zhang, J. J. He, A. Parikh +22
The Ne(,)Na reaction is thought to be one of the key breakout reactions from the hot CNO cycles to the rp-process in type I x-ray bursts. In this work, the reso…
Chromospheric variabilities of M active stars based on Guoshoujing Telescope
Q. F. Pi, L. Y. Zhang, J. R. Shi +7
For the M active catalogue of Guoshoujing Telescope (LAMOST), 933 sources are presented in at least two exposures. We found that many M active stars show chromospheric variabilitie…
Tracers of chromospheric structure. I. CaII HK emission distribution of 13000 F, G and K stars in SDSS DR7 spectroscopic sample
J. K. Zhao, T. D. Oswalt, G. Zhao +3
We present chromospheric activity index measurements for over 13,000 F, G and K disk stars with high signal-to-noise ratio ( 60) spectra in the Sloan Digital Sky Sur…
The 18Ne(a,p)21Na breakout reaction in x-ray bursts: experimental determination of spin-parities for alpha resonances in 22Mg via resonant elastic scattering of 21Na+p
J. J. He, L. Y. Zhang, A. Parikh +20
The Ne(,)Na reaction provides a pathway for breakout from the hot CNO cycles to the -process in type I x-ray bursts. To better determine this astrophysical…
Reexamination of reaction rates for a key stellar reaction of O(,p)F
J. J. He, H. W. Wang, J. Hu +5
The reaction rates of the key stellar reaction of O(,p)F have been reexamined. The previous conclusion, the 6.15-MeV state (=1) dominating this reaction r…
Reexamination of Astrophysical Resonance Reaction Rate Equations for An Isolated, Narrow Resonance
J. J. He
The well-known astrophysical resonant reaction rate equations for an isolated narrow resonance have been reexamined. The validity of those `look reliable' assumptions used in deriv…
