The Exoplanet Archive has integrated Jason Eastman's EXOFAST code into its suite of web services, which provides the tool with a more robust and stable home with several enhancements.

EXOFAST has been an important fitting tool for astronomers who want to use transit light curves or radial velocity data and various inputs to create models of planet systems. For more details, refer to Eastman et al. (2013) (

The Exoplanet Archive's version of EXOFAST offers the same IDL-based calculations as the original code, and also provides sufficient back-end computing resources to enable Markov Chain Monte Carlo (MCMC) analysis. In addition, the new EXOFAST draws on the archive's database of stellar and planetary parameters, which are updated weekly based on the current literature.

Interface enhancements include:

* Interactive tables to view, sort and filter your uploaded data before running EXOFAST.

* A preview pane to review the first 100 rows of your uploaded time series data, providing an opportunity to do a quick quality check before running EXOFAST.

* Full-color, interactive plots of input files, including color, line and point control.

* A temporary history of your results from recent EXOFAST sessions, saving
you the time and effort of re-running analyses.

To access EXOFAST, click the EXOFAST: Transit and RV Fitting button on the archive home page under Tools and Services, or mouse over Tools in the menu bar to select it from the drop-down menu.

One new microlensing planet, MOA 2012-BLG-505L b, has been added to the archive (

The Kepler project has released an updated version of the Certified False Positive Table, which added 918 newly examined KOIs and includes evaluation of all confirmed planets that were dispositioned as false positives in the DR 25 catalog. The data and log file are available on the Kepler Completeness and Reliability page. (

This week we've added HD 3167 d and HD 20794 e, both of which are new planets in existing systems. See the Confirmed Planets interactive table or their individual Confirmed Planet Overview pages.…/Tb…/nph-tblView…

Fun fact: HD 3167 d was discovered by our own archive scientist Jessie Christiansen! Here's her paper:

The hottest hot Jupiter that was announced today at the #AAS230 summer meeting is in the archive. See the data for KELT-9 b on its Confirmed Planet Overview page (, as well as the star's data on the Planet Host Overview page (

Also, read the Gaudi et al. 2017 discovery paper in Nature ( and the Ohio State University press release (

KOI DR 25 Data!

The Markov Chain Monte Carlo (MCMC) posterior chains and light curves for Kepler DR 25 KOIs are now available. To download, see the links on the Kepler Objects of Interest page ( A description of the files is also available in the documentation (

There are two new confirmed planets in the archive this week, K2-110 b ( and MOA 2016-BLG-227L b ( We also changed the default names for the following six K2 planets that were previously known by their EPIC IDs: K2-97 b, K2-98 b, K2-100 b, K2-101 b, K2-102 b, and K2-104 b. The new default names match their references in the literature.
