Using APOGEE Wide Binaries to Test Chemical Tagging with Dwarf Stars
Jeff J. Andrews, Borja Anguiano, Julio Chanamé +4
Stars of a common origin are thought to have similar, if not nearly identical, chemistry. Chemical tagging seeks to exploit this fact to identify Milky Way subpopulations through t…
On Collision Course: The Nature of the Binary Star Cluster NGC 2006 / SL 538
Marcelo D. Mora, Thomas H. Puzia, Julio Chanamé
The LMC hosts a rich variety of star clusters seen in close projected proximity. Ages have been derived for few of them showing differences up to few million years, hinting at bein…
On the Identification of Wide Binaries in the Kepler Field
Diego Godoy-Rivera, Julio Chanamé
We perform a search for wide binaries in the Kepler field with the prospect of providing new constraints for gyrochronology. First, we construct our base catalog by compiling astro…
Validating TGAS wide binaries with Gaia DR2 Radial Velocities and Parallaxes
Jeff J. Andrews, Julio Chanamé, Marcel A. Agüeros
Featuring greatly improved astrometry and precise radial velocities (RVs), the second data release (DR2) from Gaia affords us a unique opportunity to test the validity of samples o…
A Distant Sample of Halo Wide Binaries from SDSS
Johanna Coronado, María Paz Sepúlveda, Andrew Gould +1
Samples of reliably identified halo wide binaries are scarce. If reasonably free from selection effects and with a small degree of contamination by chance alignments, these wide bi…
Lithium abundance patterns of late-F stars: an in-depth analysis of the lithium desert
Claudia Aguilera-Gómez, Iván Ramírez, Julio Chanamé
We address the existence and origin of the lithium (Li) desert, a region in the Li - T_eff plane sparsely populated by stars. Here we analyze some of the explanations that have bee…
