Lithium in red giants: the roles of the He-core flash and the luminosity bump [PDF]
, 2021 Lithium abundances for red giants in the GALAH DR3 survey are studied. The rare examples of Li-enriched stars with abundances A(Li) $\geq 1.5$ are confirmed to be He-core burning stars belonging to or evolved from the red clump with similar masses and metallicity: $M\simeq 1.1\pm0.2{\rm M_\odot}$ and [Fe/H] $\simeq-0.3\pm0.3$. Li enrichment over the Li

BMC Genomics, 2023 Background It is inevitable to change the function or expression of genes during the environmental adaption of species. Both the giant panda (Ailuropoda melanoleuca) and red panda (Ailurus fulgens) belong to Carnivora and have developed similar ...

Red giants rotational splittings [PDF]
EPJ Web of Conferences, 2013 The space missions CoRoT and Kepler provide high quality data that allow to test the transport of angular momentum in stars by the seismic determination of the internal rotation profile. Our aim is to test the validity of the seismic diagnostics for red giant rotation that are based on a perturbative method and to investigate the oscillation spectra ...

Red Giant Branch stars: the theoretical framework [PDF]
Publ.Astron.Soc.Pac. 114 (2002) 375, 2002 Theoretical predictions of Red Giant Branch stars' effective temperatures, colors, luminosities and surface chemical abundances are a necessary tool for the astrophysical interpretation of the visible--near infrared integrated light from unresolved stellar populations, the Color-Magnitude-Diagrams of resolved stellar clusters and galaxies, and ...

Drivers of the Abundance of Tridacna spp. Giant Clams in the Red Sea
Frontiers in Marine Science, 2021 Giant clams (Subfamily Tridacninae), are important members of Indo-Pacific coral reefs, playing multiple roles in the framework of these communities. Although they are prominent species in Red Sea reefs, data on their distribution and densities in the ...

Dynamical Substructures of Galactic Globular Clusters I. M5 [PDF]
Journal of Astronomy and Space Sciences, 2004 CCD images to study the dynamical substructure of the globular cluster M5. We investigate the radial variation of ellipticities and position angles using the stellar photometry and the IRAF ellipse task.

Measuring the core rotation of red giant stars [PDF]
EAS Publications Series, Volume 82, 2019, pp.225-232, 2016 Red giant stars present mixed modes, which behave as pressure modes in the convective envelope and as gravity modes in the radiative interior. This mixed character allows to probe the physical conditions in their core. With the advent of long-duration time series from space-borne missions such as CoRoT and Kepler, it becomes possible to study the red ...
