Differential abundances of open clusters and their tidal tails: chemical tagging and chemical homogeneity
L. Casamiquela, Y. Tarricq, C. Soubiran +4
Well studied Open Clusters (OCs) in the Solar neighbourhood are used as reference objects to test galactic and stellar theories. For that purpose their chemical composition needs t…
OCCASO III. Iron peak and elements of 18 open clusters. Comparison with chemical evolution models and field stars
L. Casamiquela, S. Blanco-Cuaresma, R. Carrera +10
The study of open-cluster chemical abundances provides insights on stellar nucleosynthesis processes and on Galactic chemo-dynamical evolution. In this paper we present an extended…
High-resolution spectroscopic analysis of a large sample of Li-rich giants found by LAMOST
Yutao Zhou, Hongliang Yan, Jianrong Shi +6
The discovery of Li-rich giant has cast a new challenge for the standard stellar evolution models, and to resolve this issue, the number of this type object has been rapidly increa…
Modern stellar spectroscopy caveats
Sergi Blanco-Cuaresma
Multiple codes are available to derive atmospheric parameters and individual chemical abundances from high-resolution spectra of AFGKM stars. Almost all spectroscopists have their…
Fundamentals of effective cloud management for the new NASA Astrophysics Data System
Sergi Blanco-Cuaresma, Alberto Accomazzi, Michael J. Kurtz +11
The new NASA Astrophysics Data System (ADS) is designed with a serviceoriented architecture (SOA) that consists of multiple customized Apache Solr search engine instances plus a co…
Full orbital solution for the binary system in the northern Galactic disc microlensing event Gaia16aye
Łukasz Wyrzykowski, P. Mróz, K. A. Rybicki +182
Gaia16aye was a binary microlensing event discovered in the direction towards the northern Galactic disc and was one of the first microlensing events detected and alerted to by the…
