New white paper: Scientific Opportunities with Kepler & K2 Archive Data

The Kepler and K2 missions have provided an unprecedented data set with a precision and duration that will not be rivaled for decades. Even though the data has already contributed to nearly 2,500 scientific publications so far, the scientific community continues to extract new discoveries from the archive data …

New in Lightkurve: the Periodogram class

This month in Lightkurve, we have added a Periodogram class, which provides a quick and easy way to create Lomb-Scargle periodograms from LightCurve objects.

Periodograms can be used to find stellar rotation rates, or the oscillation and pulsation frequencies of stars. They are commonly used in asteroseismology to identify oscillation …

K2 Campaigns 2, 3, and 13 reprocessed

A few months ago we announced that we were undertaking an effort to reprocess campaigns 0–14 using the same version of the Kepler/K2 pipeline used for C15 and subsequent campaigns. This version introduced several new features and improvements, such as more sophisticated pixel calibration, better identification of spacecraft …
