Space-based multi-mode extrasolar terrestrial planet comprehensive detection method and system

Abstract

The invention provides a space-based multi-mode extrasolar terrestrial planet comprehensive detection method. The method comprises steps that the orbital period, the near-star-point angular distance, the ascending node position angular longitude, the near-star-point moment, the orbital dip angle and the planet radius of a planet are obtained through a star masking light curve fitting model JKTEBOP; through on-orbit long-time exposure and a large-aperture telescope, a planet is detected by adopting a radial velocity method, and planet parameters are obtained; on the basis of confirming existence of a terrestrial planet by a radial velocity method, precision spectrum and polarization detection on extrasolar planet atmosphere are carried out to obtain a structure sample, main characteristic spectral lines are covered, and inversion of planet physical and chemical characteristics is carried out according to the structure sample; near ultraviolet and far ultraviolet signals of a sky area are acquired through the ultraviolet sky patrol detector, ultraviolet background radiation is obtained, and inversion and research are carried out on the ground. The space-based multi-mode extrasolar terrestrial planet comprehensive detection method is powerful in function and novel, and is a new method and a new thought in the extrasolar terrestrial planet detection field.

Description

technical field [0001] The invention relates to the technical field of space science, in particular to a space-based multi-mode comprehensive detection method for extrasolar terrestrial planets. Background technique [0002] The search for extraterrestrial life has always been a hot spot in human space exploration, especially the terrestrial planets that are located in the habitable zone of the host star and have a mass similar to that of the earth. A breakthrough will fundamentally change human beings’ understanding of themselves and the entire universe. The carriers of extrasolar life are planets. To search for extrasolar life, we first need to search for planets that may have life. Limited by the current observation level, human beings have no understanding of extrasolar Earth-like planets. The research and understanding of planets is still not comprehensive, and it is impossible to establish a complete detection sample of terrestrial planets, which directly leads to many...

[0002] The search for extraterrestrial life has always been a hot spot in human space exploration, especially the terrestrial planets that are located in the habitable zone of the host star and have a mass similar to that of the earth. A breakthrough will fundamentally change human beings’ understanding of themselves and the entire universe. The carriers of extrasolar life are planets. To search for extrasolar life, we first need to search for planets that may have life. Limited by the current observation level, human beings have no understanding of extrasolar Earth-like planets. The research and understanding of planets is not yet comprehensive, and it is impossible to establish a complete detection sample of terrestrial planets, which directly leads to many unresolved scientific problems in scientific research related to exoplanets.
