2024年10月24日 · KELT-7 b is a gas giant exoplanet that orbits a F-type star. Its mass is 1.39 Jupiters, it takes 2.7 days to complete one orbit of its star, and is 0.04415 AU from its star. Its discovery was announced in 2015.

2015年1月22日 · Thus, KELT-7b is an ideal target for detailed characterization given its relatively low surface gravity, high equilibrium temperature, and bright host star. The rapid rotation of the star (73 ± 0.5 km/s) results in a Rossiter-McLaughlin effect with an unusually large amplitude of several hundred m/s.

It is also the brightest star around which Kilodegree Extremely Little Telescope (KELT) has discovered a transiting planet. Thus, KELT-7b is an ideal target for detailed characterization given its relatively low surface gravity, high equilibrium temperature, and bright host star.

2015年6月18日 · In this paper, we describe the discovery and confirmation of a hot Jupiter transiting the bright V = 8.54 star HD 33643, which we designate as KELT-7b. In Section 2, we summarize the discovery photometric transit signal and the follow-up photometric and spectroscopic observations.

2015年1月22日 · We report the discovery of KELT-7b, a transiting hot Jupiter with a mass of $1.28 \pm 0.18$ MJ, radius of $1.53_{-0.047}^{+0.046}$ RJ, and an orbital period of $2.7347749 \pm 0.0000039$ days.

We present the analysis of the hot-Jupiter KELT-7 b using transmission and emission spectroscopy from the Hubble Space Telescope, both taken with the Wide Field Camera 3. Our study uncovers a rich transmission spectrum that is consistent with a cloud-free atmosphere and suggests the presence of H2O and H−.

We report the discovery of KELT-7b, a transiting hot Jupiter with a mass of 1.28 Mj, radius of 1.53 R j, and an orbital period of 2.73 days. The bright host star, V=8.57, is an F star (HD33643) with Teff=6789, [Fe/H]=0.139, and log g=4.149. It has a mass of …

2020年6月25日 · We present the analysis of the hot-Jupiter KELT-7b using transmission and emission spectroscopy from the Hubble Space Telescope (HST), both taken with the Wide Field Camera 3 (WFC3). Our study uncovers a rich transmission spectrum which is consistent with a cloud-free atmosphere and suggests the presence of H2O and H-.
