3 MHz 太空天文台

3 MHz Space Observatory

J. I. Katz, J. Krassner

AI总结:

针对10 MHz以下射电观测空白,提出立方星低轨天文台,利用地球屏蔽太阳辐射,观测系外瞬变与稳态源,并研究电离层。

摘要:

由于低于10 MHz的射电辐射无法穿透电离层,人们对这一频段的射电天文宇宙知之甚少。基于立方星的天文台可在低地球轨道上快速且经济地部署,用于观测1–10 MHz频段。当地球屏蔽太阳辐射时,它能够观测到微弱的太阳系外源。我们考虑了可能的瞬变源和稳态源,并将其应用于电离层本身的研究。

英文摘要:

Little is known about the radio astronomical universe at frequencies below 10 MHz because such radiation does not penetrate the ionosphere. A cubesat-based observatory for the 1--10 MHz band could be rapidly and economically deployed in low earth orbit. When shielded by the Earth from Solar emission, it could observe weak extra-Solar System sources. We consider possible transient and steady sources, and application to study of the ionosphere itself.
