We present the discovery of 2MASS J05241392 − 0336543 (hereafter J0524 − 0336), a very metal-poor ([Fe/H]= − 2 . 43 ± 0 . 16), highly r -process-enhanced ([Eu/Fe]= +1 . 34 ± 0 . 10) Milky Way halo field red giant star, with an ultra high Li abundance of A(Li)(3D,NLTE)= 5 . 62 ± 0 . 25 and [Li/Fe]= +7 . 00 ± 0 . 25, respectively. This makes J0524 − 0336 the most lithium-enhanced giant star discovered to date. We present a detailed analysis of the star’s atmospheric stellar parameters and chemical… 



The GALAH survey: Lithium-rich giant stars require multiple formation channels

We investigate the properties of 1306 red giant stars with high photospheric abundances of lithium observed by the GALAH, K2-HERMES and TESS-HERMES surveys, and discuss them in the context of

The GALAH survey: effective temperature calibration from the InfraRed Flux Method in the Gaia system

In order to accurately determine stellar properties, knowledge of the effective temperature of stars is vital. We implement Gaia and 2MASS photometry in the InfraRed Flux Method and apply it to


The war exacts its heavy toll of human life, and science is not spared. On our side we have not forgotten the loss of the physicist Mpseley, at the threshold of a great career ; now, from the enemy,
