The consistency of chemical clocks among coeval stars
Francisca Espinoza-Rojas, Julio Chanamé, Paula Jofré +1
The abundance ratios of some chemical species have been found to correlate with stellar age, leading to the possibility of using stellar atmospheric abundances as stellar age indic…
On Lithium-6 as diagnostic of the lithium-enrichment mechanism in red giants
Claudia Aguilera-Gómez, Julio Chanamé, Marc H. Pinsonneault
High lithium-7 () abundances in giants are indicative of non-standard physical processes affecting the star. Mechanisms that could produce this signature include con…
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…
