Published on

Describes data science efforts at Berkeley, with a particular focus on teaching and the new Berkeley Institute for Data Science (BIDS), funded by the Moore and Sloan Foundations. BIDS will be a space for the open and interdisciplinary work that is typical of the SciPy community. In the creation of BIDS, open source scientific tools for data science, and specifically the SciPy ecosystem, played an important role.

Marcya a Astronomy Department, University of California, Berkeley, CA 94720; and b Institute for Astronomy, University of Hawaii at Manoa, Honolulu, HI 96822 Contributed by Geoffrey W. Marcy, October 22, 2013 (sent for review October 18, 2013) Determining whether Earth-like planets are common or rare looms as a touchstone in the question of life in the universe. We searched for Earth-size planets that cross in front of their host stars by examining the brightness measurements of 42,000 stars from National Aeronautics and Space Administration’s Kepler mission. We found 603 planets, including 10 that are Earth size (1 − 2 R⊕) and receive comparable levels of stellar energy to that of Earth (0:25 − 4 F⊕). We account for Kepler’s imperfect detectability of such planets by injecting synthetic planet–caused dimmings into the Kepler brightness measurements and recording the fraction detected. We find that 11 ± 4% of Sun-like stars harbor an Earth- size planet receiving between one and four times the stellar inten- sity as Earth. We also find that the occurrence of Earth-size planets is constant with increasing orbital period (P), within equal intervals of logP up to ∼200 d. Extrapolating, one finds 5:7+1:7 −2:2 % of Sun-like stars harbor an Earth-size planet with orbital periods of 200–400 d. extrasolar planets | astrobiology The National Aeronautics and Space Administration’s (NASA’s) Kepler mission was launched in 2009 to search for planets that transit (cross in front of) their host stars (1–4). The resulting dimming of the host stars is detectable by measuring their bright- ness, and Kepler monitored the brightness of 150,000 stars every 30 min for 4 y. To date, this exoplanet survey has detected more than 3,000 planet candidates (4). We searched for transiting planets in Kepler brightness mea- surements using our custom-built TERRA software package described in previous works (6, 9) and in SI Appendix. In brief, TERRA conditions Kepler photometry in the time domain, re- moving outliers, long timescale variability (>10 d), and systematic errors common to a large number of stars. TERRA then searches for transit signals by evaluating the signal-to-noise ratio (SNR) of prospective transits over a finely spaced 3D grid of orbital period, P, time of transit, t0, and transit duration, ΔT. This grid-based search extends over the orbital period range of 0.5–400 d. TERRA produced a list of “threshold crossing events” (TCEs) that meet the key criterion of a photometric dimming SNR ratio SNR > 12. Unfortunately, an unwieldy 16,227 TCEs met this cri- terion, many of which are inconsistent with the periodic dimming profile from a true transiting planet. Further vetting was performed by automatically assessing which light curves were consistent with theoretical models of transiting planets (10). We also visually inspected each TCE light curve, retaining only those exhibiting a consistent, periodic, box-shaped dimming, and rejecting those caused by single epoch outliers, correlated noise, and other data anomalies. The vetting process was applied homogeneously to all TCEs and is described in further detail in SI Appendix. To assess our vetting accuracy, we evaluated the 235 Kepler objects of interest (KOIs) among Best42k stars having P > 50 d, which had been found by the Kepler Project and identified as planet candidates in the official Exoplanet Archive (exoplanetarchive.

Standard weighted least-squares fitting is only appropriate when there is a dimension along which the data points have negligible uncertainties, and another along which all the uncertainties can be described by Gaussians of known variance; these D Fi Da Cen Ma Jo Cen Du Dep Prin tha dit line and ⇤ arXiv:1008.4686v1 [astro-ph.IM] 27 Aug 2010 Sta8s8cal+Inference Undergraduate$&$Graduate$Training$Mission Thinking$Data'Literacy$before$ Thinking$Big'Data'Proficiency
