具有对流过冲、太阳风质量损失和PMS盘吸积的太阳模型：日震量、Li耗尽和中微子通量
Solar models with convective overshoot, the solar-wind mass loss, and a PMS disk accretion: helioseismic quantities, Li depletion and neutrino fluxes
摘要：
日震观测揭示了太阳的许多性质：对流区的深度和氦丰度，太阳内部的声速和密度分布。这些约束条件已被用来判断恒星演化理论。与旧的太阳组成（例如，GS 98），太阳标准模型是在合理的协议与日震约束。然而，一个具有修正成分的太阳模型（例如，AGSS 09）与低丰度的重元素$Z$不符合这些限制。这就是所谓的“太阳丰度问题”，即使最近向上修正了Ne丰度，也存在了十多年。已经提出了许多机制来缓解这个问题。然而，仍然没有一个低的$Z$太阳模型满足所有日震约束。在本文中，我们报告了一个可能的解决方案的太阳丰度问题。通过添加一些标准模型中未包含的额外物理过程，可以显著改进太阳能模型。我们的新的太阳模型与对流过冲，太阳风，和早期的质量吸积与日震约束，太阳锂丰度，太阳中微子通量的观测结果一致。
英文摘要：
Helioseismic observations have revealed many properties of the Sun: the depth and the helium abundance of the convection zone, the sound-speed and the density profiles in the solar interior. Those constraints have been used to judge the stellar evolution theory. With the old solar composition (e.g., GS98), the solar standard model is in reasonable agreement with the helioseismic constraints. However, a solar model with revised composition (e.g., AGSS09) with low abundance $Z$ of heavy elements cannot be consistent with those constraints. This is the so-called "solar abundance problem", standing for more than ten years even with the recent upward revised Ne abundance. Many mechanisms have been proposed to mitigate the problem. However, there is still not a low-$Z$ solar model satisfying all helioseismic constraints. In this paper, we report a possible solution to the solar abundance problem. With some extra physical processes that are not included in the standard model, solar models can be significantly improved. Our new solar models with convective overshoot, the solar wind, and an early mass accretion show consistency with helioseismic constraints, the solar Li abundance, and observations of solar neutrino fluxes.
