Hosted by Tony Darnell.

From Oct 11, 2023.

Over the course of this show, we’ve talked many, many times about the Transit Method for detecting exoplanets. It is simply the measure of a star's decrease in brightness as the star passes through our line of sight. This once difficult measurement has now become commonplace and can even be done with advanced amateur astronomy equipment under a reasonably dark sky.

From this measurement, we can infer a few things about the planets passing by: we can get an indication of its size and if we measure several transits, we can get the period of the orbit around the host star. We can also get an estimate of the period and eccentricity of the orbit by the width of the dip in the light curve.

But there is another, even more difficult measurement we can make using transit telescopes that are an important tool for learning about planets around other stars: exoplanet secondary eclipses.
