Known sources of lithium (Li) in the universe include the Big Bang, novae, asymptotic giant branch stars, and cosmic-ray spallation. During their longer-lived evolutionary phases, stars are not expected to add to the Li budget of the Galaxy, but to largely deplete it. In this context, recent analyses of Li data from GALAH and LAMOST for field red clump (RC) stars have concluded that there is the need for a new production channel of Li, ubiquitous among low-mass stars, and that would be…

Discovery of ubiquitous lithium production in low-mass stars

The vast majority of stars with mass similar to that of the Sun are expected to destroy lithium (Li) gradually over the course of their lives, via low-temperature nuclear burning. This has now been

Tidal Interactions between Binary Stars Can Drive Lithium Production in Low-mass Red Giants

Theoretical models of stellar evolution predict that most of the lithium inside a star is destroyed as the star becomes a red giant. However, observations reveal that about 1% of red giants are

The GALAH survey: A census of lithium-rich giant stars

We investigate the properties of 1262 red giant stars with high photospheric abundances of lithium observed by the GALAH and K2-HERMES surveys, and discuss them in the context of proposed

Lithium in M 67: From the main sequence to the red giant branch

Lithium abundances in open clusters are a very effective probe of mixing processes, and their study can help to understand the large depletion of lithium in the Sun. Due to its age and metallicity,

Lithium abundance patterns of late-F stars: an in-depth analysis of the lithium desert

Aims. We address the existence and origin of the lithium (Li) desert, a region in the Li–Teff plane sparsely populated by stars. Here we analyze some of the explanations that have been suggested for

Lithium-rich Giants in LAMOST Survey. I. The Catalog

Standard stellar evolution model predicts a severe depletion of lithium (Li) abundance during the first dredge up process (FDU). Yet a small fraction of giant stars are still found to preserve a

Ultra-Lithium-deficient Halo Stars and Blue Stragglers: A Common Origin?

We present data for four ultra-Li-deficient, warm, halo stars. The Li deficiency of two of these is a new discovery. Three of the four stars have effective temperatures Teff ~ 6300 K, in contrast to

Gaia-ESO survey: Lithium abundances in open cluster Red Clump stars

Context. It has recently been suggested that all giant stars with masses below 2 M (cid:12) su ff er an episode of surface lithium enrichment between the tip of the red giant branch (RGB) and the red

Explosive lithium production in the classical nova V339 Del (Nova Delphini 2013)

The detection of highly blue-shifted resonance lines of the singly ionized radioactive isotope of beryllium, 7Be, in the near-ultraviolet spectra of the classical nova V339 Del (Nova Delphini 2013) 38 to 48 days after the explosion supports the theoretical prediction that a significant amount of 7Li is produced in classicalNova explosions.

The GALAH survey: a new constraint on cosmological lithium and Galactic lithium evolution from warm dwarf stars

Lithium depletion and enrichment in the cosmos is not yet well understood. To help tighten constraints on stellar and Galactic evolution models, we present the largest high-resolution analysis of
