长基线干涉测量:大质量恒星多重性研究的一个有前途的工具

Long baseline interferometry: a promising tool for multiplicity investigations of massive stars

M. De Becker

摘要:

大质量双星是至关重要的实验室,使我们能够研究在相当极端的条件下发生的过程,例如粒子加速,高能发射,甚至尘埃形成。所有这些过程都密切依赖于二元性。我们对基本物理的理解强烈需要初步的多重性研究,可能会发现尚未发现的双星,并确定它们的轨道参数。然而,经典的光谱方法有时无法提供解决这个问题的方案。长基线干涉测量术被证明是解决大质量恒星多样性问题的一种有前途的补充技术。已经与VLTI发起了一场运动,以利用这一技术。

英文摘要:

Massive binaries are crucial laboratories that allow us to investigate processes occurring in quite extreme conditions, such as particle acceleration, high-energy emission, or even dust formation. All these processes are intimately dependent on binarity. Our understanding of the underlying physics strongly requires preliminary multiplicity studies likely to uncover still undetected binaries, and determine their orbital parameters. However, classical spectroscopic approaches sometimes fail to provide a solution to this issue. Long baseline interferometry turns out to be a promising complementary technique to address the question of the multiplicity of massive stars. A campaign has been initiated with the VLTI to take benefit of this technique.
