In the search for habitable exoplanets, the authors of today’s paper turn their gaze to our own planet, and what we can learn from NASA’s DSCOVR:EPIC observations of Earth.
With the launch of TESS, we will soon have many more exoplanet candidates. But how do we determine which are the most valuable for follow-up observations?
Astronomers are using a once-secret technology to scrutinize Kepler stars. Are rocky planets headed for a takedown?
Using new Gaia data, the authors update the stellar radii for the majority of Kepler’s stars. While they find that most stars have similar radii to previous reported values, there are some large discrepancies.
Using MC simulations, these authors seek to find how many Earth-like exoplanets will be detectable with future direct imaging missions.
Statistical confirmation of long-period, low SNR candidates should be taken with a grain of salt. The reliability is too low to confirm individual systems without followup observations and the 99% confidence validation of Kepler-452b is likely closer to 90%.
