利用空间引力波探测器探测致密双星周围的行星

Detecting Planets around Compact Binaries with Gravitational Wave Detectors in Space

Naoki Seto

摘要:

我提出了一种方法来探测行星周围的紧凑的双星,是强大的引力辐射源。这种方法是测量引力波相位调制的行星,并与Fisher矩阵分析的前景进行了研究。我发现,使用激光干涉仪空间天线(LISA),可以搜索到大约3000个银河系双白矮星的行星,检测限为~4 M_J(M_J~ 2 × 10 ^{30}g:木星质量)。随着后续任务的开展,即使在宇宙学距离z~1处,也可能在双中子星周围探测到质量为~1 M_J的行星。以这种方式,引力波观测有可能对太阳系外行星科学做出有趣的贡献。

英文摘要:

I propose a method to detect planets around compact binaries that are strong sources of gravitational radiation. This approach is to measure gravitational-wave phase modulations induced by the planets, and its prospect is studied with a Fisher matrix analysis. I find that, using the Laser Interferometer Space Antenna (LISA), planets can be searched for around ~3000 Galactic double white dwarfs with detection limit ~4 M_J (M_J~ 2x10^{30}g: the Jupiter mass). With its follow-on missions, planets with mass ~1 M_J might be detected around double neutron stars even at cosmological distances z~1. In this manner, gravitational wave observation has potential to make interesting contributions to extra-solar planetary science.
