Astronomical observations of elemental and isotopic abundances provide the means to determine the source of elements and to reveal their evolutionary pathways since the formation of the Galaxy some 15 billion years ago. The abundance of lithium is particularly interesting because, although some of it is thought to be primordial, most results from spallation reactions (in which Galactic cosmic rays break apart larger nuclei in the interstellar medium). Spallation reactions are crucial for the… 
Observation of interstellar lithium in the low-metallicity Small Magellanic Cloud
TLDR
Observations of interstellar 7Li in the low-metallicity gas of the Small Magellanic Cloud, a nearby galaxy with a quarter the Sun’s metallicity, are reported, showing an alternative constraint on the primordial abundance and cosmic evolution of lithium that is not susceptible to the in situ modifications that may affect stellar atmospheres.
An Ultra-High-Resolution Survey of the Interstellar 7Li/6Li Isotope Ratio in the Solar Neighborhood
In an effort to probe the extent of variations in the interstellar 7Li/6Li ratio seen previously, ultra-high-resolution (R ~ 360,000), high signal-to-noise spectra of stars in the Perseus OB2 and
Boron abundances in diffuse interstellar clouds
Abstract We present a comprehensive survey of B abundances in diffuse interstellar clouds from HST/STIS observations along 56 Galactic sight lines. Our sample is the result of a complete search of
THE NEW DETECTIONS OF 7Li/6Li ISOTOPIC RATIO IN THE INTERSTELLAR MEDIA
We have determined the isotopic abundance ratio of 7Li/6Li in the interstellar media (ISMs) along lines of sight to HD169454 and HD250290 using the High-Dispersion Spectrograph on the Subaru
Galactic Chemical Evolution of Lithium: Interplay between Stellar Sources
In this paper we study the evolution of 7Li in the Galaxy considering the contributions of various stellar sources: Type II supernovae, novae, red giant stars, and asymptotic giant branch (AGB)
Evidence for planet engulfment by the star HD82943
TLDR
The discovery of 6Li in the atmosphere of the metal-rich solar-type star HD82943, which is known to have an orbiting giant planet, can probably be interpreted as evidence for a planet (or planets) having been engulfed by the parent star.
THE ABUNDANCE OF BORON IN DIFFUSE INTERSTELLAR CLOUDS
We present a comprehensive survey of boron abundances in diffuse interstellar clouds from observations made with the Space Telescope Imaging Spectrograph (STIS) of the Hubble Space Telescope. Our
Parsec-scale Variations in the 7 Li I/ 6 Li I Isotope Ratio Toward IC 348 and the Perseus OB 2 Association
Measurements of the lithium isotopic ratio in the diffuse interstellar medium from high-resolution spectra of the Li i λ6708 resonance doublet have now been reported for a number of lines of sight.
THE 7Li/6Li ISOTOPE RATIO NEAR THE SUPERNOVA REMNANT IC 443
We present an analysis of 7Li/6Li isotope ratios along four sight lines that probe diffuse molecular gas near the supernova remnant IC 443. Recent gamma-ray observations have revealed the presence of
RUBIDIUM IN THE INTERSTELLAR MEDIUM
We present observations of interstellar rubidium toward o Per, ζ Per, AE Aur, HD 147889, χ Oph, ζ Oph, and 20 Aql. Theory suggests that stable 85Rb and long-lived 87Rb are produced predominantly by

We reevaluate the contribution of Galactic cosmic ray (GCR) spallation to the abundances of the Li, Be, and B elements at various metallicities. We calculate absolute yields, as was formerly done by
