Modules for Experiments in Stellar Astrophysics (MESA): Convective Boundaries, Element Diffusion, and Massive Star Explosions
Blinnikov, Sergei; Townsend, Richard H. D.; Bildsten, Lars +10 more
We update the capabilities of the software instrument Modules for Experiments in Stellar Astrophysics (MESA) and enhance its ease of use and availability. Our new approach to locating convective boundaries is consistent with the physics of convection, and yields reliable values of the convective-core mass during both hydrogen- and helium-burning p…
The Dark Energy Survey: Data Release 1
Benoit-Lévy, A.; Bechtol, K.; Juneau, S. +201 more
We describe the first public data release of the Dark Energy Survey, DES DR1, consisting of reduced single-epoch images, co-added images, co-added source catalogs, and associated products and services assembled over the first 3 yr of DES science operations. DES DR1 is based on optical/near-infrared imaging from 345 distinct nights (2013 August to …
Planetary Candidates Observed by Kepler. VIII. A Fully Automated Catalog with Measured Completeness and Reliability Based on Data Release 25
Dupree, Andrea K.; Barclay, Thomas; Bryson, Steve +59 more
We present the Kepler Object of Interest (KOI) catalog of transiting exoplanets based on searching 4 yr of Kepler time series photometry (Data Release 25, Q1-Q17). The catalog contains 8054 KOIs, of which 4034 are planet candidates with periods between 0.25 and 632 days. Of these candidates, 219 are new, including two in multiplanet systems (KOI-8…
The Absolute Magnitude of the Sun in Several Filters
Willmer, Christopher N. A.
This paper presents a table with estimates of the absolute magnitude of the Sun and the conversions from vegamag to the AB and ST systems for several wide-band filters used in ground-based and space-based observatories. These estimates use the dustless spectral energy distribution (SED) of Vega, calibrated absolutely using the SED of Sirius, to se…
The 105-Month Swift-BAT All-sky Hard X-Ray Survey
Cenko, S. Bradley; Schawinski, Kevin; Koss, Michael +10 more
We present a catalog of hard X-ray sources detected in the first 105 months of observations with the Burst Alert Telescope (BAT) coded-mask imager on board the Swift observatory. The 105-month Swift-BAT survey is a uniform hard X-ray all-sky survey with a sensitivity of 8.40× {10}-12 {erg} {{{s}}}-1 {cm}}-2 over 90…
The Second APOKASC Catalog: The Empirical Approach
Chaplin, William J.; Cunha, Katia; Smith, Verne V. +33 more
We present a catalog of stellar properties for a large sample of 6676 evolved stars with Apache Point Observatory Galactic Evolution Experiment spectroscopic parameters and Kepler asteroseismic data analyzed using five independent techniques. Our data include evolutionary state, surface gravity, mean density, mass, radius, age, and the spectroscop…
Dark Energy Survey Year 1 Results: The Photometric Data Set for Cosmology
Benoit-Lévy, A.; Bechtol, K.; Smith, M. +87 more
We describe the creation, content, and validation of the Dark Energy Survey (DES) internal year-one cosmology data set, Y1A1 GOLD, in support of upcoming cosmological analyses. The Y1A1 GOLD data set is assembled from multiple epochs of DES imaging and consists of calibrated photometric zero-points, object catalogs, and ancillary data products—e.g…
Asteroseismology of 16,000 Kepler Red Giants: Global Oscillation Parameters, Masses, and Radii
Huber, Daniel; Bedding, Timothy R.; Stello, Dennis +4 more
The Kepler mission has provided exquisite data to perform an ensemble asteroseismic analysis on evolved stars. In this work we systematically characterize solar-like oscillations and granulation for 16,094 oscillating red giants, using end-of-mission long-cadence data. We produced a homogeneous catalog of the frequency of maximum power (typical un…
The SINS/zC-SINF Survey of z ∼ 2 Galaxy Kinematics: SINFONI Adaptive Optics-assisted Data and Kiloparsec-scale Emission-line Properties
Lutz, D.; Wuyts, S.; Cimatti, A. +29 more
We present the “SINS/zC-SINF AO survey” of 35 star-forming galaxies, the largest sample with deep adaptive optics (AO)-assisted near-infrared integral field spectroscopy at z ∼ 2. The observations, taken with SINFONI at the Very Large Telescope, resolve the Hα and [N II] emission and kinematics on scales of ∼1.5 kpc. The sample probes the massive …
The Hipparcos-Gaia Catalog of Accelerations
Brandt, Timothy D.
This paper presents a cross-calibrated catalog of Hipparcos and Gaia astrometry to enable their use in measuring changes in proper motion, i.e., accelerations in the plane of the sky. The final catalog adopts the reference frame of the second Gaia data release (DR2) and locally cross-calibrates both the scaled Hipparcos-Gaia DR2 positional differe…
