Earth Like Exoplanets(像地球一樣的系外行星)到底是什麼?
Earth Like Exoplanets 像地球一樣的系外行星 - The extent of core formation has profound consequences for the subsequent planetary surface environment and may provide additional constraints in the hunt for habitable, Earth-like exoplanets. [1] The interaction between Earth-like exoplanets and the magnetic field of low-mass host stars are considered to produce weak emission signals at radio frequencies. [2] A starshade suppresses starlight by a factor of 1011 in the image plane of a telescope, which is crucial for directly imaging Earth-like exoplanets. [3] The long-term carbonate silicate cycle plays an important role in the evolution of Earth’s climate and, therefore, may also be an important mechanism in the evolution of the climates of Earth-like exoplanets. [4] As a technology demonstrator, the instrument’s main purpose is to mature the various technologies needed by future flagship mission concepts that aim to image and characterize Earth-like exoplanets. [5] These problems must be solved to enable novel missions such as the Earth-Orbiting Starshade, which uses a 100m starshade with extremely large ground telescopes to image earth-like exoplanets with an effective inner working angle of only 50 milliarcseconds. [6] The driving objective of the concept is to determine whether Earth-like exoplanets exist in the HZs of the nearest sunlike stars and have biosignature gases in their atmospheres. [7] The dynamic pressures exerted by CIRs are 1300 times larger than those observed from the Sun and can contribute to the atmospheric erosion of early Venus, Earth, Mars, and young Earth-like exoplanets. [8] The exploration of circumstellar environments by means of direct imaging to search for Earth-like exoplanets is one of the challenges of modern astronomy. [9] The detection and characterization of Earth-like exoplanets is one of the major science drivers for the next generation of telescopes. [10] Detection of similar extended exospheres around Earth-like exoplanets could reveal crucial facts in terms of habitability. [11] Starshades are a leading technology to enable the direct detection and spectroscopic characterization of Earth-like exoplanets. [12] One of the primary science goals of the Large UV/Optical/Infrared Surveyor (LUVOIR) mission concept is to detect and characterize Earth-like exoplanets around nearby stars with direct imaging. [13] To achieve the ambitious science goal of performing direct imaging of earth-like exoplanets with a high contrast coronagraph, future space-based astronomical telescopes will require wavefront stability several orders of magnitude beyond state-of-the-art. [14] The in-plane deployment accuracy must be on the order of hundreds of micrometers for sufficient starlight suppression to enable the detection and study of Earth-like exoplanets around nearby Sun-like stars. [15] A key aspect of the search for earth-like exoplanets with direct imaging, is determining if the exoplanet is in the habitable zone. [16] Aside from its direct imaging of Earth-like exoplanets, it will have a general-observatory complement of instrumentation. [17]核心形成的程度對隨後的行星表面環境具有深遠的影響,並可能為尋找可居住的類地系外行星提供額外的限制。 [1] 類地系外行星與低質量宿主恆星的磁場之間的相互作用被認為會在無線電頻率上產生微弱的發射信號。 [2] 星影在望遠鏡的像平面中將星光抑制了 1011 倍,這對於直接成像類地系外行星至關重要。 [3] 長期的碳酸鹽矽酸鹽循環在地球氣候演化中發揮著重要作用,因此也可能是類地系外行星氣候演化的重要機制。 [4] 作為技術演示器,該儀器的主要目的是使未來旗艦任務概念所需的各種技術成熟,這些概念旨在成像和表徵類地系外行星。 [5] 必須解決這些問題才能實現新的任務,例如地球軌道星影,它使用 100m 的星影和超大的地面望遠鏡對類地系外行星進行成像,有效內部工作角僅為 50 毫秒。 [6] 該概念的驅動目標是確定類地系外行星是否存在於最近的類太陽恆星的 HZ 中,並在其大氣中具有生物特徵氣體。 [7] CIR 施加的動態壓力是從太陽觀測到的壓力的 1300 倍,並可能導致早期金星、地球、火星和年輕的類地系外行星的大氣侵蝕。 [8] 通過直接成像探索星際環境以尋找類地系外行星是現代天文學的挑戰之一。 [9] 類地系外行星的探測和表徵是下一代望遠鏡的主要科學驅動因素之一。 [10] 在類地系外行星周圍探測到類似的擴展外逸層可以揭示宜居性方面的關鍵事實。 [11] 星影是一項領先的技術,可以直接檢測和光譜表徵類地系外行星。 [12] 大型紫外/光學/紅外測量員 (LUVOIR) 任務概念的主要科學目標之一是通過直接成像檢測和表徵附近恆星周圍的類地系外行星。 [13] 為了實現雄心勃勃的科學目標,即使用高對比度日冕儀對類地系外行星進行直接成像,未來的天基天文望遠鏡將需要比最先進技術高出幾個數量級的波前穩定性。 [14] 平面內部署精度必須達到數百微米,才能充分抑制星光,從而能夠探測和研究附近類太陽恆星周圍的類地系外行星。 [15] 通過直接成像尋找類地系外行星的一個關鍵方面是確定係外行星是否在宜居帶內。 [16] 除了對類地系外行星的直接成像外,它還將配備通用天文台的儀器補充。 [17]
exoplanet direct imaging 系外行星直接成像
Future exoplanet direct imaging missions, such as HabEx and LUVOIR, will select target stars to maximize the number of Earth-like exoplanets that can have their atmospheric compositions characterized. [1] Future, large-scale, exoplanet direct-imaging missions will be capable of discovering and characterizing Earth-like exoplanets and star systems like our solar system. [2] Future, large-scale, exoplanet direct-imaging missions will be capable of discovering and characterizing Earth-like exoplanets. [3]未來的系外行星直接成像任務,如 HabEx 和 LUVOIR,將選擇目標恆星,以最大限度地增加可以表徵其大氣成分的類地系外行星的數量。 [1] 未來,大規模的系外行星直接成像任務將能夠發現和表徵類地系外行星和太陽係等恆星系統。 [2] 未來的大規模系外行星直接成像任務將能夠發現和表徵類地系外行星。 [3]
