Journal ArticleDOI
Quantifying radial migration in the Milky Way: Inefficient over short timescales but essential to the very outer disc beyond ∼15 kpc
Jianhui Lian,Gail Zasowski,Sten Hasselquist,Jon A. Holtzman,Nicholas Fraser Boardman,Katia Cunha,J. G. Fern'andez-Trincado,Peter M. Frinchaboy,D. A. García-Hernández,Christian Nitschelm,Richard R. Lane,Daniel Thomas,Kai Zhang +12 more
TL;DR: In this article , the authors revisited reported observational evidence for radial migration and quantified its strength using the age-Fe/H distribution of stars across the Milky Way with APOGEE data.
Journal ArticleDOI
High-resolution spectroscopic observations of the peculiar planetary nebula Me 1-1
TL;DR: In this paper, the atmospheric parameters and evolutionary state of the cool stellar component of the peculiar planetary nebula Me 1-1 and analyzed its spatio-kinematic structure were determined.
Journal ArticleDOI

Rafael Guerço,Katia Cunha,Verne V. Smith,C. B. Pereira,Carlos Abia,David L. Lambert,Patrick de Laverny,Alejandra Recio-Blanco,Henrik Jönsson +8 more
TL;DR: In this paper, the chemical abundances for the elements carbon, sodium, and fluorine in 15 red giants of the globular cluster M 4, as well as six red giants (probabilistic) of the Globular Cluster $\omega$ Centauri were calculated via spectral synthesis.
Journal ArticleDOI
The Origin of Fluorine: Abundances in AGB Carbon Stars Revisited
TL;DR: In this article, the spectral properties of AGB carbon stars with respect to their fluorine abundances were determined using new spectroscopic tools and LTE spectral synthesis, using several HF lines in the K-band in a sample of Galactic and extragalactic carbon stars.
Journal Article
Is Geminga a runaway member of the Orion association
TL;DR: Using the age and distance estimates for the neutron star Geminga, as well as its measured proper motion, this article examined the possible space motions of the star in an attempt to determine the origin of its progenitor star.
