31st Oct 2018: Goodbye Kepler

Goodbye Kepler. You will be missed!
We can all take solace in the fact that the amazing data you have provided us will keep up busy, making new discoveries, for years to come.
Now, take a well-deserved rest - you have earned it!

21st Aug 2018: TASC4/KASC11 Conference Material

The slides, posters and photos from the TASC4/KASC11 conference in Aarhus, Denmark has now been made available on KASOC and TASOC. If you have any other material, like good photos you took during the conference, feel free to e-mail them to us and we can include it on the page.

30th Oct 2018: 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 …
