Kepler-62: A five-planet system with planets of 1.4 and 1.6 Earth radii in the Habitable Zone
W. J. Borucki, E. Agol, F. Fressin +62
We present the detection of five planets -- Kepler-62b, c, d, e, and f -- of size 1.31, 0.54, 1.95, 1.61 and 1.41 Earth radii, orbiting a K2V star at periods of 5.7, 12.4, 18.2, 12…
Star Formation Rates in Resolved Galaxies: Calibrations with Near and Far Infrared Data for NGC5055 and NGC6946
Yiming Li, Alison F. Crocker, Daniela Calzetti +21
We use the near--infrared Brγhydrogen recombination line as a reference star formation rate (SFR) indicator to test the validity and establish the calibration of the {\it Herschel}…
The WiggleZ Dark Energy Survey: measuring the cosmic growth rate with the two-point galaxy correlation function
Carlos Contreras, Chris Blake, Gregory B. Poole +24
The growth history of large-scale structure in the Universe is a powerful probe of the cosmological model, including the nature of dark energy. We study the growth rate of cosmic s…
Bringing the Visible Universe into Focus with Robo-AO
Christoph Baranec, Reed Riddle, Nicholas M. Law +13
Light from astronomical objects must travel through the earth's turbulent atmosphere before it can be imaged by ground-based telescopes. To enable direct imaging at maximum theoret…
A proper motion study of the globular clusters M4, M12, M22, NGC 3201, NGC 6362 and NGC 6752
K. Zloczewski, J. Kaluzny, M. Rozyczka +3
We derive relative proper motions of stars in the fields of globular clusters M4, M12, M22, NGC 3201, NGC 6362 and NGC 6752 based on a uniform data set collected between 1997 and 2…
