Abstract

The VISTA Magellanic Clouds Survey (VMC) is a near-infrared survey of the Magellanic system. The VMC data has been exploited to detect and study statistically correlated young groups of stars - also known as "young stellar structures" - in the Large and Small Magellanic Clouds (LMC and SMC). We showcase the ~ 3000 recently detected young stellar structures in the LMC and their similarity to the fractal interstellar medium. We discuss how their properties indicate their formation mechanisms and that there are no preferred scales of star formation in the LMC.

摘要

VISTA麦哲伦星系巡天（VMC）是一项对麦哲伦星系系统进行的近红外巡天。VMC数据已被用于探测和统计研究大麦哲伦星系（LMC）和小麦哲伦星系（SMC）中统计上相关的年轻恒星群——也被称为“年轻恒星结构”。我们展示了在LMC中最近探测到的约3000个年轻恒星结构及其与分形星际介质的相似性。我们讨论了它们的性质如何表明其形成机制，以及在LMC中不存在恒星形成的优先尺度。
