研究目的
To describe how the observables from secondary eclipses can be used to deduce physical characteristics of exoplanets such as averaged dayside emission, departures from uniform disk illumination, or precise measurement of orbital eccentricity.
研究成果
Secondary eclipse measurements have become a powerful tool for characterizing exoplanets, providing insights into their physical and atmospheric properties. Despite challenges, the technique has yielded significant results over the past 12 years and holds promise for future discoveries with upcoming missions.
研究不足
The observations are challenging due to the need for precise control of instrumental systematic effects. The interpretation of results is complicated by the need to separate contributions from reflected light and thermal emission, and by nonuniform temperatures across the planet's disk.
1：Experimental Design and Method Selection:
The methodology involves measuring the time of occultation, its depth, and its color during secondary eclipses to deduce physical characteristics of exoplanets.
2：Sample Selection and Data Sources:
The study includes observations of over 80 exoplanets with reported secondary eclipse detections, primarily from space telescopes Spitzer, Hubble, or Kepler, and ground-based observations.
3：List of Experimental Equipment and Materials:
Utilizes space telescopes (Spitzer, Hubble, Kepler) and ground-based instrumentation for observations.
4：Experimental Procedures and Operational Workflow:
Involves scheduling observations at half a period after a transit event for planets assumed to have circular orbits, and measuring the flux of the system before, during, and after the secondary eclipse.
5：Data Analysis Methods:
Analysis includes measuring the timing offset due to finite light speed, eclipse depth for thermal emission and reflected light, and wavelength dependence for low-resolution spectra of the dayside emission.
