Kepler-47: A Transiting Circumbinary Multiplanet System [PDF]

Science, 2012
A Pair of Planets Around a Pair of Stars Most of the planets we know about orbit a single star; however, most of the stars in our galaxy are not single. Based on data from the Kepler space telescope, Orosz et al. (p.

Discovery of a Third Transiting Planet in the Kepler-47 Circumbinary System [PDF]

The Astronomical Journal, 2019
Abstract Of the nine confirmed transiting circumbinary planet systems, only Kepler-47 is known to contain more than one planet. Kepler-47 b (the “inner planet”) has an orbital period of 49.5 days and a radius of about 3 R ⊕. Kepler-47 c (the “outer planet”) has an orbital period of 303.2 days and a radius of about 4.7 R

PREDICTING A THIRD PLANET IN THE KEPLER-47 CIRCUMBINARY SYSTEM [PDF]

The Astrophysical Journal, 2015
We have studied the possibility that a third circumbinary planet in the Kepler-47 planetary system be the source of the single unexplained transiting event reported during the discovery of these planets. We applied the MEGNO technique to identify regions in the phase space where a third planet can maintain quasi-periodic orbits, and assessed the long ...

The Habitable Zone of Kepler-47 Binary System

Astronomy and Astrophysics, 2016
一颗系外行星上如果存在生命，它需要位于其寄主恒星的宜居带中。本文考虑了恒星有效温度对宜居带的影响，给出了双星宜居带的内、外边界的距离满足的方程。我们用数值法求出了开普勒-47双星系统的宜居带，其内、外边界的平均半径分别为0.77761和1.55287AU。开普勒-47内行星距离双星比较近，不在宜居带中。开普勒-47外行星围绕双星公转的轨道可能是一个椭率为0.411的椭圆，它的远日点处在宜居带中，而近日点不在宜居带中。在一个公转周期内，它有237.837至239.056天的时间处在宜居带中，而有64.102至65.321天的时间不在宜居带中。 Provided that there are lives living on an exoplanet, it must be located in the ...

An Experimental Approach to Determining the Average Diffusion Coefficient of Volatile Components in Polymer Waste Materials

Recycling, 2023
One of the major challenges in recycling plastics is the removal of undesired volatile components from the polymeric phase, which may reduce process efficiency and negatively affect product quality.

Using a Novel Process-Near Mechanical-Deflection-Based Spreading Test Rig for a Systematic Experimental Analysis of Carbon Fiber Rovings Spreading Process

Fibers
Unidirectional (UD) fiber-reinforced thermoplastic tapes provide excellent specific mechanical properties; thus, they are being increasingly used for the targeted local reinforcement of plastic components in lightweight construction applications.

The Multiband Imaging Survey for High-alpha PlanetS (MISHAPS). I. Preliminary Constraints on the Occurrence Rate of Hot Jupiters in 47 Tucanae

The Astronomical Journal
The first generation of transiting planet searches in globular clusters yielded no detections, and in hindsight only placed occurrence rate limits slightly higher than the measured occurrence rate in the higher-metallicity Galactic thick disk. To improve

Terrestrial Exoplanet Internal Structure Constraints Enabled by Comprehensive Host Star Characterization Reveal That Terrestrial Planets in Mean Motion Resonances Are Water Rich

The Astrophysical Journal
Exoplanet mass and radius inferences fundamentally rely on host star mass and radius inferences. Despite the importance of host star mass, radius, and elemental abundance inferences for the derivation of exoplanet internal structure constraints ...
