We present 130 ultracool dwarf discoveries with estimated distances $ \ approx9 - 130 $ pc, including 21 that were independently discovered by other authors and 3 that were previously identified as
photometric candidates.
We have confirmed the membership to Collinder 69 of \ sim90
photometric candidate members.

Results from the
photometric follow - up of CoRoT
candidates (Deeg et al. 2009) show that most of the diluted binaries that have been identified from low - amplitude (0.1 - 0.5 %)
candidates fall into the magnitude range of 16 - 19.
Two more objects in our sample show evidence of
photometric J - band variability, and two others are
candidate unresolved binaries based on their spectra.

candidates discovered using data from the first year of the NASA K2 mission (Campaigns 0 - 4), along with the results of an intensive program of

In order to identify false positives and confirm transiting exoplanets, we have assembled a follow - up network (KELT - FUN) to conduct imaging with higher spatial resolution, cadence, and
photometric precision than the KELT telescopes, as well as spectroscopic observations of the
candidate host stars.
Statistical tests on the
photometric and pixel flux time series established the viability of the planet
candidates triggering ground - based follow - up observations.
A blend may consist of a background or foreground eclipsing binary (or star - planet pair) whose eclipses are attenuated by the light of the
candidate and possibly other stars within the
photometric aperture.
Follow - up observations of planetary
candidates identified by detection of transit - like events are needed both for identification of astrophysical phenomena that mimic planetary transits and for characterization of the... ▽ More The Kepler Mission was launched on March 6, 2009 to perform a
