Kepler Input Catalog

The Kepler Input Catalog (or KIC) is a publicly searchable database of roughly 13.2 million targets used for the Kepler Spectral Classification Program (SCP) and Kepler.[1][2]

Overview

The Kepler SCP targets were observed by the 2MASS project as well as Sloan filters, such as the griz filters.[3] The catalog alone is not used for finding Kepler targets, because only a portion (about 1/3 of the catalog) can be observed by the spacecraft.[1] The full catalog includes up to 21 magnitude, giving 13.2 million targets, but of these only about 6.5 to 4.5 million fall on Kepler's sensors.[1]

KIC is one of the few comprehensive star catalogs for a spacecraft's field of view.[4] The KIC was created because no catalog of sufficient depth and information existed for target selection at that time.[5] The catalog includes "mass, radius, effective temperature, log (g), metallicity, and reddening extinction".[5]

An example of a KIC catalog entry is KIC #10227020. Having had transit signals detected for this star, it has become a Kepler Object of Interest, with the designation KOI-730.[6]

Not all star Kepler Input Catalog stars with confirmed planets get a Kepler Object of Interest designation. The reason is that sometimes transit signals are detected by observations not made by Kepler team. An example of one of these objects is Kepler-78b.[7]

The unusual light curve of KIC 8462852 (also designated TYC 3162-665-1 and 2MASS J20061546+4427248), which was flagged by Planet Hunters,[8] has engendered speculation that an alien civilization's Dyson sphere[9][10] is responsible.[11]

gollark: I don't want to *have* to arbitrarily trust people. This is why I do things like "TLS" and "not giving everyone my SSH keys".
gollark: ????
gollark: It would be possible, although stupid, to make a cryptocurrency where new blocks can only be issued by GTech™ bee cuboids using a private signing key, although this may break some of the security incentives.
gollark: This is just a feature of proof of work, not all cryptocurrency. Not that there are good alternatives right now.
gollark: Well, Nim is basically compiled statically typed compile-time-instead-of-runtime-metaprogramming-capable somewhat immature mildly more expression-oriented Python.
