标题： A Possible Origin of Gamma Ray Bursts and Axionic Boson Stars

摘要： 我们指出了一种可能产生伽马射线暴的机制。 它们是由轴子玻色子星与中子星碰撞产生的。 轴子玻色子星可以在中子星的磁化导电介质中耗散其全部能量$10^{50}$尔格。 这种耗散仅发生在中子星的外壳附近，因此预计会产生一个具有少量重子污染的火球。 在合理的假设下，我们粗略地评估了每年每银河系的碰撞率，这与观测结果一致。 我们还指出，具有极高能量的宇宙射线， $10^{21}$电子伏特，可以在类似与强磁场中子星碰撞时产生，磁场强度为$\sim 10^{14}$高斯。 显示英文摘要

摘要： We indicate a possible mechanism of generating gamma ray bursts. They are generated by a collision between an axionic boson star and a neutron star. The axionic boson star can dissipates its whole energy $10^{50}$ erg in the magnetized conducting medium of the neutron star. This dissipation arises only around envelope of the neutron star so that a fire ball with small baryon contamination is expected. We have evaluated roughly a rate of the collision per year and per galaxy which is consistent with observations, under plausible assumptions. We also point out that cosmic rays with extremely high energy, $10^{21}$eV, can be produced in the similar collisions with the neutron stars with strong magnetic fields $\sim 10^{14}$G.
