Exoplanet Radio Ep. 41: Exoplanet Secondary Eclipses: Catching a Planet in the Shadows

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.
