In the spring of 2009, the Kepler Mission commenced high-precision photometry on nearly 156,000 stars to determine the frequency and characteristics of small exoplanets, conduct a guest observer program, and obtain asteroseismic data on a wide variety of stars. On 2010 June 15, the Kepler Mission released most of the data from the first quarter of observations. At the time of this data release, 705 stars from this first data set have exoplanet candidates with sizes from as small as that of Earth to larger than that of Jupiter. Here we give the identity and characteristics of 305 released stars with planetary candidates. Data for the remaining 400 stars with planetary candidates will be released in 2011 February. More than half the candidates on the released list have radii less than half that of Jupiter. Five candidates are present in and near the habitable zone; two near super-Earth size, and three bracketing the size of Jupiter. The released stars also include five possible multi-planet systems. One of these has two Neptune-size (2.3 and 2.5 Earth radius) candidates with near-resonant periods.

ARCHITECTURE AND DYNAMICS OF KEPLER'S CANDIDATE MULTIPLE TRANSITING PLANET SYSTEMS (2011, background): “Borucki et al. (2011a) presented 5 Kepler targets with multiple transiting planet candidates, and these candidate planetary systems were analyzed by Steffen et al. (2010).”

(2011b), who detected three large, long-period transiting planet candidates, which eventually would be known as Kepler-90 e, g, and h.”
AN ALL-SKY CATALOG OF BRIGHT M DWARFS (2011, background): “…planet search team reports that>30% of low-mass stars harbor planets with masses<30M⊕ on orbits shorter than 50 d (Mayor et al. 2009) and preliminaryKepler results suggest that M dwarfs host just as many, if not more, super-Earths and Neptunes as solar-mass stars (Borucki et al. 2011b).”
A STELLAR-MASS-DEPENDENT DROP IN PLANET OCCURRENCE RATES (2014, methodology): “…characterize the occurrence rate of terrestrial planets in the habitable zone, while the largest yield of Kepler planets and planetary candidates (KOIs) is super-Earths and subNeptunes with orbital periods shorter than any planet in our solar system (e.g., Borucki et al. 2011; Batalha et al. 2013).”
The Derivation, Properties, and Value of Kepler’s Combined Differential Photometric Precision (2012, background): “…changes in the stellar signal, which increases the scatter in the observations, and therefore the measured CDPP.
