False positive probabilities for all Kepler objects of interest: 1284 newly validated planets and 428 likely false posit... PDF available through Get Fulltext Research

Timothy D, Morton Stephen T, Bryson Jeffrey Coughlin Jason Rowe Ganesh, Ravichandran Erik A, Petigura Michael R, Haas Natalie M, Batalha

Published in The Astrophysical Journal

We present astrophysical false positive probability calculations for every Kepler Object of Interest (KOI)—the first large-scale demonstration of a fully automated transiting planet validation procedure. Out of 7056 KOIs, we determine that 1935 have probabilities

The role of the atmospheric electric field in the dust‐lifting process

Esposito, F Molinaro, R Popa, C I Molfese, C Cozzolino, F Marty, L Taj‐eddine, K Di Achille, G Franzese, G Silvestro, S ...

Published in Geophysical Research Letters

Mineral dust particles represent the most abundant component of atmospheric aerosol in terms of dry mass. They play a key role in climate and climate change, so the study of their emission processes is of utmost importance. Measurements of dust emission into the atmosphere are scarce, so that the dust load is generally estimated using models. It is...

The Foreign Clast Populations of Anomalous Polymict Urelite Almahata Sitta (Asteroid 2008 TC(sub3) and Typical Polymict ...

C. A., Goodrich A. H., Treiman M., Zolensky N. T., Kita C., Defouilloy A. M., Fioretti D. P., O Brien P., Jenniskens M. H., Shaddad

Almahata Sitta (AhS) is the first meteorite to originate from an asteroid (2008 TC3) that had been studied in space before it hit Earth [1,2]. It is also unique because the fallen fragments comprise a variety of types: approximately 69% ureilites (achondrites) and 31% chondrites [3]. Two models have been proposed for the origin 2008 TC3: 1) an accr...

The Frequency of Giant Impacts on Earth-like Worlds

Elisa Quintana Barclay, Thomas Borucki, William J Jason Rowe Chambers, John E

Published in The Astrophysical Journal

The late stages of terrestrial planet formation are dominated by giant impacts that collectively influence the growth, composition, and habitability of any planets that form. Hitherto, numerical models designed to explore these late stage collisions have been limited by assuming that all collisions lead to perfect accretion, and many of these studi...

Detection of Potential Transit Signals in 17 Quarters of Kepler Data: Results of the Final Kepler Mission Transiting Pla... PDF available through Get Fulltext Research

Joseph Twicken Jon M, Jenkins Shawn E, Seader Peter Tenenbaum Jeffrey Smith Lee S, Brownston Christopher Burke Joseph Catanzarite Bruce Clarke Miles T, Cote ...

Published in arXiv preprint arXiv:1604.06140

We present results of the final Kepler Data Processing Pipeline search for transiting planet signals in the full 17-quarter primary mission dataset. The search includes a total of 198,709 stellar targets of which 112,046 were observed in all 17 quarters and 86,663 in fewer than 17 quarters. We report on 17,230 targets for which at least one transit...

Orbital evidence for more widespread carbonate‐bearing rocks on Mars

Wray, James J Murchie, Scott L Janice Bishop Ehlmann, Bethany L Milliken, Ralph E Wilhelm, Mary Beth Seelos, Kimberly D

Published in Journal of Geophysical Research: Planets

Carbonates are key minerals for understanding ancient Martian environments because they are indicators of potentially habitable, neutral-to-alkaline water and may be an important reservoir for paleoatmospheric CO 2. Previous remote sensing studies have identified mostly Mg-rich carbonates, both in Martian dust and in a Late Noachian rock unit circu...

Orbital Observations of Dust Lofted by Daytime Convective Turbulence

Fenton, Lori Reiss, Dennis Lemmon, Mark Marticorena, Béatrice Lewis, Stephen Cantor, Bruce

Published in Space Science Reviews

Over the past several decades, orbital observations of lofted dust have revealed the importance of mineral aerosols as a climate forcing mechanism on both Earth and Mars. Increasingly detailed and diverse data sets have provided an ever-improving understanding of dust sources, transport pathways, and sinks on both planets, but the role of dust in m...

The Institute of Physics (IOP) is a leading scientific society promoting physics and bringing physicists together for the benefit of all. It has a worldwide membership of around 50 000 comprising physicists from all sectors, as well as those with an interest in physics. It works to advance physics research, application and education; and engages wi...

Retrieval of Precise Radial Velocities from Near-Infrared High Resolution Spectra of Low Mass Stars

Gao, Peter Plavchan, Peter Gagné, Jonathan Furlan, Elise Bottom, Michael Anglada-Escudé, Guillem White, Russel Davison, Cassy Beichman, Charles Brinkworth, Carolyn ...

Given that low-mass stars have intrinsically low luminosities at optical wavelengths and a propensity for stellar activity, it is advantageous for radial velocity (RV) surveys of these objects to use near-infrared (NIR) wavelengths. In this work we describe and test a novel RV extraction pipeline dedicated to retrieving RVs from low mass stars usin...

SECURE MASS MEASUREMENTS FROM TRANSIT TIMING: 10 KEPLER EXOPLANETS BETWEEN 3 AND 8 M? WITH DIVERSE DENSITIES AND INCIDEN...

Jontof-Hutter, Daniel Ford, Eric B Jason Rowe Lissauer, Jack J Fabrycky, Daniel C Van Laerhoven, Christa Agol, Eric Deck, Katherine M Holczer, Tomer Mazeh, Tsevi ...

Published in The Astrophysical Journal

We infer dynamical masses in eight multiplanet systems using transit times measured from Kepler s complete data? set, including short-cadence data where available. Of the 18? dynamical masses that we infer, 10? pass multiple tests for robustness. These are in systems? Kepler-26 (KOI-250), Kepler-29 (KOI-738), Kepler-60 (KOI-2086), Kepler-105 (KOI-1...
