CoRoT-7c is an extrasolar planet which orbits the G-type main sequence star CoRoT-7, located approximately 489 light years away in the constellation Monoceros. It is either a super-Earth or a Neptune -like planet, orbiting at 0.046 AU from the star, taking 3.7 days or 89 hours to make one round trip around the star.

2024年10月25日 · CoRoT-7 c is a Neptune-like exoplanet that orbits a K-type star. Its mass is 8.4 Earths, it takes 3.7 days to complete one orbit of its star, and is 0.046 AU from its star. Its discovery was announced in 2009.

柯洛7c是一颗环绕corot-7运行的太阳系外行星，位于麒麟座，距离地球约497光年。 它在2009年由 法国 主持的 柯洛计划 所发现。 它的质量是地球的8.4B倍，和COROT-7的平均距离为0.046个 天文单位 ，围绕COROT-7公转一周的时间为3.698个地球日(88.8小时) [ 1 ] 。

CoRoT-7 (TYC 4799-1733-1) is a binary star system made up of a late G-type star [1] and a M-dwarf star that was discovered in 2021. [3] The primary star has three exoplanets , [ 5 ] including CoRoT-7b , a super-Earth exoplanet that is remarkable due to its extremely high temperature (around 2000 °C) and very short orbital period , around 20 hours.

2022年6月28日 · Here we present an analysis of the HARPS archival RV data of CoRoT-7 using a new wavelength-domain technique, scalpels, to correct for the stellar activity-induced spectral line-shape changes.

COROT-7 (柯洛7)，是一颗位于 麒麟座 的G9V型恒星，比太阳稍小，距离地球约489光年，视星等为11.7，裸眼无法直接看到它。 研究发现COROT-7的表面温度为5275K，质量是太阳的0.93，半径为太阳的0.87，显示这是一颗G9V型恒星。 但有一些数据却显示它是一颗KV型恒星。 这颗恒星有和太阳几乎一样多的金属量，达到0.03 ± 0.06 [M/H]。 年龄约12－23亿年。 2009年2月3日，法国柯洛计划利用凌星观测法发现COROT-7有一颗行星— COROT-7b，这颗行星是迄今为止所 …

Our model was incorporated into a Monte Carlo Markov Chain in order to make a precise determination of the orbits of CoRoT-7b and CoRoT-7c. We measure the masses of planets b and c to be 4.73 ± 0.95 and 13.56 ± 1.08 M ⊕, respectively.

We attribute the second signal to a second, more remote planet CoRoT-7c . The orbital solution of both planets is compatible with circular orbits. The mass of CoRoT-7b is ( ) and that of CoRoT-7c is ( ), assuming both planets are on coplanar orbits.
