To the Editors: I am surprised to read that Dr. Strojnik ("Direct Detection of Exoplanets," September-October2023) states that we have not yet and cannot directly image exoplanets (外部行星). This is incorrect. NASA/IPAC has a list at exoplanetarchive.ipac.caltech.edu/does/imaging.html. One example is an image of 51 Eridani b. The planet is 2.6 times as massive as Jupiter and has the same radius (半径). Gerard Kriss Space Telescope Science Institute |
Dr. Gerard: I am pleased that my article brought a response. The phrase "planet detection" arouses in people's imaginations beautiful images of planets that are creative artistic representations of novel worlds. But a blur of brightness is not an image. Exoplanet researchers routinely call videos such as the one below of 51 Eridani b "direct images" because the planet's light has been separated from that of its star. "Directly imaged" is the standard language of exoplanet astronomy. But to an optical (光学的) scientist such as myself, there is a strong distinction between direct detection (the planet's light separated from the light of its star) and direct imaging (a proven picture of the exoplanet). From an optical researcher's perspective, a single bright spot simply is not an image. Indeed, even the word "direct" in direct detection is debatable from an optical researcher's point of view. The detection of the light of the exoplanet requires significant processing, adding multiple images and removing starlight based on theoretical models of the source signal. But the interpretation of a bright spot as a planet is only possible upon visual inspection and optimistic thinking. As an optical scientist, I cannot look at a single spot and call it an image of exoplanets. A trajectory (轨迹), or a series of bright points, is not an image of a planet, although it very likely represents something that nowadays is described as an exoplanet. Marija Strojnik |
