APOGEE [C/N] Abundances Across the Galaxy: Migration and Infall from Red Giant Ages
Sten Hasselquist, Jon A. Holtzman, Matthew Shetrone +14
We present [C/N]-[Fe/H] abundance trends from the SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey, Data Release 14 (DR14), for red giant branch stars…
Predicting Granulation "Flicker" and Radial Velocity "Jitter" from Spectroscopic Observables
Jamie Tayar, Keivan G. Stassun, Enrico Corsaro
Surface granulation can be predicted with the mass, metallicity, and frequency of maximum power of a star. Using the orders-of-magnitude larger APOGEE-Kepler sample, we recalibrate…
The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
Velocity-resolved reverberation mapping of five bright Seyfert 1 galaxies
G. De Rosa, M. M. Fausnaugh, C. J. Grier +99
We present the first results from a reverberation-mapping campaign undertaken during the first half of 2012, with additional data on one AGN (NGC 3227) from a 2014 campaign. Our ma…
APOGEE Data Releases 13 and 14: Data and Analysis
Jon A. Holtzman, Sten Hasselquist, Matthew Shetrone +23
Data and analysis methodology used for the SDSS/APOGEE Data Releases 13 and 14 are described, highlighting differences from the DR12 analysis presented in Holtzman (2015). Some imp…
Testing Angular Momentum Transport and Wind Loss in Intermediate Mass Core Helium Burning Stars
Jamie Tayar, Marc H. Pinsonneault
Stars between two and three solar masses rotate rapidly on the main sequence, and their rotation rates in the core helium burning (secondary clump) phase can therefore be used to t…
Discovery of a Candidate Black Hole - Giant Star Binary System in the Galactic Field
Todd A. Thompson, Christopher S. Kochanek, Krzysztof Z. Stanek +14
We report the discovery of the first likely black hole in a non-interacting binary system with a field red giant. By combining radial velocity measurements from the Apache Point Ob…
The Second APOKASC Catalog: The Empirical Approach
Marc H. Pinsonneault, Yvonne P. Elsworth, Jamie Tayar +33
We present a catalog of stellar properties for a large sample of 6676 evolved stars with APOGEE spectroscopic parameters and \textit{Kepler} asteroseismic data analyzed using five…
The K2 M67 Study: A Curiously Young Star in an Eclipsing Binary in an Old Open Cluster
Eric L. Sandquist, Robert D. Mathieu, Samuel N. Quinn +16
We present an analysis of a slightly eccentric (), partially eclipsing long-period ( d) main sequence binary system (WOCS 12009, Sanders 1247) in the benchmark o…
Continuum Reverberation Mapping of the Accretion Disks in Two Seyfert 1 Galaxies
M. M. Fausnaugh, D. A. Starkey, Keith Horne +69
We present optical continuum lags for two Seyfert 1 galaxies, MCG+08-11-011 and NGC 2617, using monitoring data from a reverberation mapping campaign carried out in 2014. Our light…
KELT-21b: A Hot Jupiter Transiting the Rapidly-Rotating Metal-Poor Late-A Primary of a Likely Hierarchical Triple System
Marshall C. Johnson, Joseph E. Rodriguez, George Zhou +65
We present the discovery of KELT-21b, a hot Jupiter transiting the A8V star HD 332124. The planet has an orbital period of days and a radius of $…
