Stellar properties available for EPIC targets from Campaigns 1-8

The K2 Ecliptic Plane Input Catalog (EPIC), which is hosted at MAST, has been updated to include stellar classifications for 138,600 targets (~88% of all targets) in Campaigns 1-8. The stellar properties were derived using colors, proper motions, spectroscopy, parallaxes, and galactic population synthesis models. This update supports target ...

Raw data for K2 Campaign 9a now available at MAST

The currently on-going K2 Campaign 9 is dedicated to a microlensing experiment, aimed at simultaneously observing gravitional microlensing events with K2 and from Earth in order to see a parallax effect in the shape and time of the lensing events. To allow such events to be identified and characterized rapidly ...

K2 Campaigns 11, 12 and 13 Director's Discretionary Targets Program

As in Cycle 3, the Guest Observer (GO) Office is providing a faster mechanism for headline astrophysics in K2 GO Cycle 4, via the Director's Discretionary Target (DDT) program. The purpose of the DDT program for K2 is to:

  • respond to targets of opportunity, e.g. newly discovered exoplanets ...
