标题： Formation gf Bosonic Compact Objects

摘要： 我们证明了通过我们称为引力冷却的过程，可以形成紧致的玻色子物体。 该领域中的一个核心问题是，由克莱因-戈登方程描述的经典场配置，{\it 例如，}是否能够坍缩形成类似致密星体的物体，因为克莱因-戈登方程显然没有耗散。 我们证明了一种有效的冷却机制，可以通过引力耦合纯粹地消除形成致密物体的动能，这是一种所有自引力场普遍适用的机制。 讨论了这一机制的影响，包括宇宙中玻色子星的丰富性，以及排除轴子作为暗物质候选的可能性。 显示英文摘要

摘要： We showed that compact bosonic objects can be formed through a process we called gravitational cooling. A central issue in the subject of boson star is whether a classical field configuration, {\it e.g.,} one described by the Klein-Gordon equation, can collapse to form a compact star-like object, as there is apparently no dissipation in the Klein-Gordon equation. We demonstrated that there IS an efficient cooling mechanism to get rid of the kinetic energy for the formation of a compact object purely through the gravitational coupling, a mechanism universal to all self-graviting fields. Implications of this mechanism are discussed, including the abundance of bosonic stars in the universe, and the possibility of ruling out the axion as a dark matter condidate.
