The KESPRINT Consortium
The KESPRINT Consortium is a multi-national collaboration for the discovery, confirmation and characterization of planet candidates from the K2 and TESS space missions. Given the limited amount of telescope time, our natural focus is the detection of the most exciting objects, rather than attempting to provide complete catalogues.
We have three main scientific goals.
1) Measure the masses of rocky planets. This requires discovering planets with ultra-short orbits orbiting bright stars, so that these measurements are achievable with current instruments.
2) Discovery of low-density planets suitable for atmospheric characterization. While low-density Earth-size planets will be out of reach, our goal to search for low-density gaseous planets of any size.
3) To conduct a search for hot and habitable zone rocky planets around all the M-dwarfs in the K2 fields, which are brighter than I=13 mag.
Our team has several pipelines for the detection of planet candidates from the K2 and TESS raw light curves, and has been awarded competitive open time at international telescopes.

KESPRINT does not have any guaranteed time for the follow up efforts of planet candidates, and relies on open time applications. Nevertheless, our team has an excellent track record in this respect, and we regularly obtain time for:
AO, Speckle, and Lucky Imaging: AO188@Subaru Telescope, NESSI@WIYN, and FC@TCS
Seeing limited photometry: MUSCAT@Okayima, MUSCAT2@TCS, and CAMELOT@IAC80
Reconnaissance spectroscopy and moderate-precision radial velocity (3-10 m/s): FIES@NOT, and Tull@2.7m-McDonald Observatory
- Highly stable spectrographs (~1 m/s): HARPS@3.6m-ESO, HARPS-N@TNG, HDS@SUBARU, CARMENES@CaHa, and HIRES@Keck
