论文摘要
在进化的最早阶段，恒星通过从出生云中获取物质而获得质量。早期恒星进化的广泛接受的经典概念忽略了该增生阶段的细节，并假定具有重力收缩的巨大初始半径的恒星形成。在这张照片中，一个共同的想法是，一旦星星开始融合过程，他们就忘记了过去。通过分析最近出生的恒星中的恒星振荡，我们表明增生历史在恒星的内部结构上留下了可检测到的烙印。当前来自空间的可用数据将允许区分这些更现实的积聚方案和经典的早期恒星演化模型。这打开了一个窗口，以研究年轻脉动星的内部结构，这也将与相关场（例如一般的恒星振荡和系外行星研究）相关。
In the earliest phases of their evolution, stars gain mass through the acquisition of matter from their birth clouds. The widely accepted classical concept of early stellar evolution neglects the details of this accretion phase and assumes the formation of stars with large initial radii that contract gravitationally. In this picture, the common idea is that once the stars begin their fusion processes, they have forgotten their past. By analysing stellar oscillations in recently born stars, we show that the accretion history leaves a potentially detectable imprint on the stars' interior structures. Currently available data from space would allow discriminating between these more realistic accretion scenarios and the classical early stellar evolution models. This opens a window to investigate the interior structures of young pulsating stars that will also be of relevance for related fields, such as stellar oscillations in general and exoplanet studies.
