Surveying for Close Binaries among Lithium-rich Giants
Jesús Torres, Sebastián Vilaza-Dallago, Julio Chanamé +1
One of the possible scenarios usually considered to explain the existence of low-mass red giants with anomalously high lithium (Li) abundances requires the interaction with a close…
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…
Improved Constraints on the Initial-to-Final Mass Relation of White Dwarfs using Wide Binaries
Manuel Barrientos, Julio Chanamé
We present observational constraints for the initial-to-final mass relation (IFMR) derived from 11 white dwarfs (WDs) in wide binaries (WBs) that contain a turnoff/subgiant primary…
The S2 Stream: the shreds of a primitive dwarf galaxy
David S. Aguado, G. C. Myeong, Vasily Belokurov +12
The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called the Helmi stream. We…
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…
Detection of the nearest Jupiter analog in radial velocity and astrometry data
Fabo Feng, Guillem Anglada-Escudé, Mikko Tuomi +4
The presence of Jupiter is crucial to the architecture of the Solar System and models underline this to be a generic feature of planetary systems. We find the detection of the diff…
