The 2MIG isolated AGNs -- 4. Linking hot-dust reverberation to spectroscopically predicted BLR scales in IC~5287 and Mrk~845
I. O. Izviekova, I. B. Vavilova, O. V. Kompaniiets +2
We investigate the relation between directly measured hot-dust reverberation scales and spectroscopically predicted broad-line region (BLR) scales in the isolated Seyfert galaxies…
The 2MIG isolated AGNs. 3. Optical--IR variability and dust reverberation in the NLSy1 galaxies Mrk~42 and Mrk~493
I. O. Izviekova, I. B. Vavilova, O. V. Kompaniiets +2
This work presents the first dedicated optical--mid-infrared time-domain variability and dust-reverberation analysis of the isolated NLSy1 galaxies Mrk 42 and Mrk 493. We combine Z…
Heavy element abundances in P-rich stars: A new site for the s-process?
T. Masseron, D. A. García-Hernández, O. Zamora +1
The recently discovered phosphorus-rich stars pose a challenge to stellar evolution and nucleosynthesis theory, as none of the existing models can explain their extremely peculiar…
Cool stars in the Galactic Center as seen by APOGEE: M giants, AGB stars and supergiant stars/candidates
M. Schultheis, A. Rojas-Arriagada, K. Cunha +11
The Galactic Center region, including the nuclear disk, has until recently been largely avoided in chemical census studies because of extreme extinction and stellar crowding. Makin…
Physical characterization of 2020 AV2, the first known asteroid orbiting inside Venus orbit
M. Popescu, J. de León, C. de la Fuente Marcos +8
The first known asteroid with the orbit inside that of Venus is 2020~AV. This may be the largest member of a new population of small bodies with the aphelion smaller than 0.7…
Chemical Abundances of Main-Sequence, Turnoff, Subgiant and red giant Stars from APOGEE spectra II: Atomic Diffusion in M67 Stars
Diogo Souto, C. Allende Prieto, Katia Cunha +14
Chemical abundances for 15 elements (C, N, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, and Ni) are presented for 83 stellar members of the 4 Gyr old solar-metallicity open cluster…
Chemical and kinematic analysis of CN-strong Metal-poor Field Stars in LAMOST DR3
Baitian Tang, Chao Liu, J. G. Fernandez-Trincado +5
The large amount of chemical and kinematic information available in large spectroscopic surveys have inspired the search for chemically peculiar stars in the field. Though these me…
APOGEE Data Releases 13 and 14: Stellar Parameter and Abundance Comparisons With Independent Analyses
Henrik Jönsson, Carlos Allende Prieto, Jon A. Holtzman +18
Data from the SDSS-IV / Apache Point Observatory Galactic Evolution Experiment (APOGEE-2) have been released as part of SDSS Data Releases 13 (DR13) and 14 (DR14). These include hi…
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…
Stellar and Planetary Characterization of the Ross 128 Exoplanetary System from APOGEE Spectra
Diogo Souto, Cayman T. Unterborn, Verne V. Smith +14
The first detailed chemical abundance analysis of the M dwarf (M4.0) exoplanet-hosting star Ross 128 is presented here, based upon near-infrared (1.5--1.7 \micron) high-resolution…
Chemical Abundances of Main-Sequence, Turn-off, Subgiant and red giant Stars from APOGEE spectra I: Signatures of Diffusion in the Open Cluster M67
Diogo Souto, Katia Cunha, Verne V. Smith +21
Detailed chemical abundance distributions for fourteen elements are derived for eight high-probability stellar members of the solar metallicity old open cluster M67 with an age of…
Abundance anomalies in red giants with possible extragalactic origins unveiled by APOGEE-2
J. G. Fernández-Trincado, D. Geisler, E. Moreno +3
By performing an orbital analysis within a Galactic model including a bar, we found that it is plausible that the newly discovered stars that show enhanced Al and N accompanied by…
Rubidium and zirconium abundances in massive Galactic asymptotic giant branch stars revisited
V. Perez-Mesa, O. Zamora, D. A. Garcia-Hernandez +4
Luminous Galactic OH/IR stars have been identified as massive (>4-5 M_s) AGB stars experiencing HBB and Li production. Their Rb abundances and [Rb/Zr] ratios derived from hydrostat…
