Kelt 9 M DL : raide à la toile ou pas - Hisse Et Oh
j'ai noté que le kelt 9 m était beaucoup plus léger que ses concurants un peu plus long : Attalia, Feeling 920, First 305 et Etap 30. Plus étroit à la flottaison, il est beaucoup moins raide à la toile que les autres, malgré un rapport de lest très important.
发现一颗超高温行星比恒星温度还要高，但为什没有燃起来呢？
kelt-9b的凌日是由kelt首次观测到，该项目两台机器人望远镜观测数据。 作为任务长达一年的北方天空观测活动的一部分，苔丝号观测了27次KELT-9b凌日 ...
For Hottest Planet, a Major Meltdown, Study Shows
2020年1月24日 · Called KELT-9b, the planet is an ultra-hot Jupiter, one of several varieties of exoplanets - planets around other stars - found in our galaxy. It weighs in at nearly three times the mass of our own Jupiter and orbits a star some 670 light-years away.
行星KELT-9b到底有多热？为何它是宇宙中最热的，有何独特之处？
KELT-9B已知的最热的气体气体巨型系外行星，其日侧温度在4050到4600 开尔文之间（表面温度高达3780摄氏度），这使得它比M型星和K型恒星更热。 它围绕着HD195689（或KELT-9）运行，HD 195689是一颗晚期的B型主序星，距地球约620 光年（190秒）。 主星的温度为10170开尔文，这是很值得注意的，因为在热星的轨道上通常不会探测到行星；作为参考，在发现凯尔特-9B之前，只有六颗A型星已知有行星（Wasp-33，一颗温度为7430K的A型星，在KELT-9b被发现之 …

2018年7月2日 · Astronomers have found that the atmosphere of the hottest known exoplanet, the hot Jupiter-like planet KELT-9b, is "boiling off," with the escaping gas being captured by the host star. Using the CARMENES instrument at Calar Alto Observatory, Fei Yan and Thomas Henning of the Max Planck Institute for Astronomy in Heidelberg were able to detect ...
Geometry of the KELT-9 system a, Schematic of the
With an equilibrium temperature of about 4,050 kelvin4, the exoplanet KELT-9b (also known as HD 195689b) is an archetype of the class of ultrahot Jupiters that straddle the transition between...
[2301.10406] Multi-epoch detections of the extended atmosphere …
2023年1月25日 · Of the Jovian planets that have been catalogued to date, KELT-9b is the hottest Gas Giant known, with an equilibrium temperature of 4050 K. We probe the temporal variability of transmission spectroscopic signatures from KELT-9b via a set of archival multi-year ground-based transit observations, performed with the TRES facility on the 1.5 m ...
