The TESS Objects of Interest Catalog from the TESS Prime Mission
Jayaraman, Rahul; Pál, András; Torres, Guillermo +102 more
We present 2241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its 2 yr Prime Mission. We list these candidates in the TESS Objects of Interest (TOI) Catalog, which includes both new planet candidates found by TESS and previously known planets recovered by TESS observations. We describe the p…
CHIANTI—An Atomic Database for Emission Lines. XVI. Version 10, Further Extensions
Young, P. R.; Del Zanna, G.; Dere, K. P. +1 more
We present version 10 of the CHIANTI package. In this release, we provide updated atomic models for several helium-like ions and for all the ions of the beryllium, carbon, and magnesium isoelectronic sequences that are abundant in astrophysical plasmas. We include rates from large-scale atomic structure and scattering calculations that are in many…
The JPL Planetary and Lunar Ephemerides DE440 and DE441
Park, Ryan S.; Folkner, William M.; Williams, James G. +1 more
The planetary and lunar ephemerides called DE440 and DE441 have been generated by fitting numerically integrated orbits to ground-based and space-based observations. Compared to the previous general-purpose ephemerides DE430, seven years of new data have been added to compute DE440 and DE441, with improved dynamical models and data calibration. Th…
Accurate distances to Galactic globular clusters through a combination of Gaia EDR3, HST, and literature data
Baumgardt, H.; Vasiliev, E.
We have derived accurate distances to Galactic globular clusters by combining data from the Gaia Early Data Release 3 (EDR3) with distances based on Hubble Space Telescope (HST) data and literature-based distances. We determine distances either directly from the Gaia EDR3 parallaxes, or kinematically by combining line-of-sight velocity dispersion …
Gaia Early Data Release 3. The Gaia Catalogue of Nearby Stars
Prusti, T.; Mazeh, T.; Zucker, S. +420 more
Aims: We produce a clean and well-characterised catalogue of objects within 100 pc of the Sun from the Gaia Early Data Release 3. We characterise the catalogue through comparisons to the full data release, external catalogues, and simulations. We carry out a first analysis of the science that is possible with this sample to demonstrate its po…
The Dark Energy Survey Data Release 2
Bacon, D.; Bechtol, K.; Juneau, S. +135 more
We present the second public data release of the Dark Energy Survey, DES DR2, based on optical/near-infrared imaging by the Dark Energy Camera mounted on the 4 m Blanco telescope at Cerro Tololo Inter-American Observatory in Chile. DES DR2 consists of reduced single-epoch and coadded images, a source catalog derived from coadded images, and associ…
Refining the Transit-timing and Photometric Analysis of TRAPPIST-1: Masses, Radii, Densities, Dynamics, and Ephemerides
Triaud, Amaury H. M. J.; Foreman-Mackey, Daniel; Meadows, Victoria S. +32 more
We have collected transit times for the TRAPPIST-1 system with the Spitzer Space Telescope over four years. We add to these ground-based, HST, and K2 transit-time measurements, and revisit an N-body dynamical analysis of the seven-planet system using our complete set of times from which we refine the mass ratios of the planets to the star. We next…
A catalogue of white dwarfs in Gaia EDR3
Gänsicke, B. T.; Jordan, S.; Tremblay, P. -E. +7 more
We present a catalogue of white dwarf candidates selected from Gaia Early Data Release 3 (EDR3). We applied several selection criteria in absolute magnitude, colour, and Gaia quality flags to remove objects with unreliable measurements while preserving most stars compatible with the white dwarf locus in the Hertzsprung-Russell diagram. We then use…
A tidal disruption event coincident with a high-energy neutrino
Kilpatrick, Charles D.; Foley, Ryan J.; Cenko, S. Bradley +55 more
Cosmic neutrinos provide a unique window into the otherwise hidden mechanism of particle acceleration in astrophysical objects. The IceCube Collaboration recently reported the likely association of one high-energy neutrino with a flare from the relativistic jet of an active galaxy pointed towards the Earth. However a combined analysis of many simi…
The MOSDEF Survey: The Evolution of the Mass-Metallicity Relation from z = 0 to z 3.3
Barro, Guillermo; Siana, Brian; Shapley, Alice E. +15 more
We investigate the evolution of galaxy gas-phase metallicity (O/H) over the range z = 0-3.3 using samples of ~300 galaxies at z ~ 2.3 and ~150 galaxies at z ~ 3.3 from the MOSDEF survey. This analysis crucially utilizes different metallicity calibrations at z ~ 0 and z > 1 to account for evolving interstellar medium (ISM) conditions. We find si…
