There are still a lot of unknowns when it comes to extrasolar planet formation. Today’s authors take a look at a group of known terrestrial exoplanets to see if they can find a correlation between the planets’ compositions and the chemical abundances of their host stars.
The field of ecology already has standardized models for determining a region’s habitability. How can astrobiologists use these models to determine habitability beyond Earth?
Lightcurve folding is frequently used to make signals in the data clearer. Today’s author describes a novel way to use the folding method to pick out exomoon signals from exoplanet transit lightcurves.
When the rotation of a star is misaligned from the orbits of its planets, astronomers often attribute the misalignment to planetary dynamics. In the case of K2-290 A, today’s authors instead attribute its misalignment to its stellar companion.
There is a low occurrence rate of exoplanets between 1.5 and 2.0 Earth radii. Today’s authors explore the density of the stellar field the planet resides in as a potential contributor to this gap.
