题目:宇宙中的恒星、行星与生命物质的孕育
摘要:人类现已发现数千颗围绕太阳以外恒星运转的行星。但这些系外行星究竟在何处、以何种方式诞生?它们又为何与太阳系内的行星差异巨大?构成行星的物质组分都有哪些?借助詹姆斯・韦伯空间望远镜等新一代高性能望远镜,天文学家如今得以近距离观测行星的形成区域,并研究其物质组分。在恒星形成区附近,探测到了水以及种类超乎想象的丰富有机物质。这些物质能否输送至新生行星,成为宇宙其他地方孕育生命的基础?
报告人介绍: Ewine van Dishoeck为荷兰莱顿大学分子天体物理学教授。她的研究团队将化学、物理学与天文学研究相结合。她深度参与了詹姆斯・韦伯空间望远镜(JWST)、阿塔卡马大型毫米波 / 亚毫米波阵列(ALMA)等大型新一代望远镜的规划工作,斩获多项重要奖项,其中包括 2018 年Kavli Prize for Astrophysics,同时也是多家科学院院士。20182021 年间,Ewine担任国际天文学联合会(IAU)主席。

Title: Building stars, planets and the ingredients for life in space
Abstract: Thousands of planets have been discovered around stars other than our Sun. But how and where are these exo-planets born, and why are they so different from those in our own solar system? Which ingredients are available to build them? Thanks to powerful new telescopes, including the James Webb Space Telescope, astronomers can now zoom in to planetary construction sites and study their composition. Water and a surprisingly rich variety of organic materials are found near forming stars. Can they be delivered to new planets to form the basis for life elsewhere in the universe?
Brief CV:
Ewine van Dishoeck is professor of molecular astrophysics at Leiden University, the Netherlands. The work of her group unites the world of chemistry with that of physics and astronomy. She has been heavily involved in planning major new telescopes, including JWST and ALMA, and has been fortunate to receive many awards, including the 2018 Kavli Prize for Astrophysics, as well as membership of several academies. From 2018-2021, Ewine served as the President of the International Astronomical Union (IAU).
