Description
The discovery is reported of a new lithium super-rich carbon star, IY Hya, and the Li abundance in three other carbon stars (T Sgr, WZ Cas and WX Cyg), previously known as super Li-rich stars is derived. All these stars show abundances in the range log N(Li) = 4.5 (i.e., 10 to 100 times higher than the present cosmic value). Two of them (WX Cyg and T Sgr) present variations in the Li feature when compared with previous studies.

    Calibrating the Clock of JWST
    JWST, despite not being designed to observe astrophysical phenomena that vary on rapid timescales, can be an unparalleled tool for such studies. If timing systematics can be controlled, JWST will be able to open up the subsecond infrared timescale regime. Rapid time-domain studies, such as lag measurements in accreting compact objects and solar

    Comparing metallicity correlations in nearby non-AGN and AGN-host galaxies
    The gas-phase metallicity distribution within galaxies records critical information about galactic evolution. In this work, we investigate how active galactic nuclei (AGNs) influence this distribution by measuring the two-point correlation functions of gas-phase metallicity in 95 non-AGN and 37 AGN-host galaxies from the Calar Alto Legacy Integral

    Why do some ultra diffuse Galaxies have rich globular cluster systems?
    Some ultra diffuse galaxies (UDGs) reveal many more globular clusters (GCs) than classical dwarf galaxies of the same stellar mass. These UDGs, with a mass in their GC system ( $M_{\rm GC}$) approaching 10 per cent of their host galaxy stellar mass ( $M_{\ast }$), are also inferred to have high halo mass to stellar mass ratios ( $M_{\rm halo}/M_{
