Can Life develop in the expanded habitable zones around Red Giant Stars?

, 2005
We present some new ideas about the possibility of life developing around sub-giant and red giant stars. Our study concerns the temporal evolution of the habitable zone.

Variations in the Na-O anticorrelation in globular clusters: Evidence for a deep mixing episode in red giant branch stars

, 2010
The Na-O anticorrelation seen in almost all globular clusters ever studied using high-resolution spectroscopy is now generally explained by the primordial pollution from the first generation of the intermediate-mass asymptotic giant branch stars to the ...

Comparative transcriptome and methylome of polar bears, giant and red pandas reveal diet‐driven adaptive evolution

Evolutionary Applications
Epigenetic regulation plays an important role in the evolution of species adaptations, yet little information is available on the epigenetic mechanisms underlying the adaptive evolution of bamboo‐eating in both giant pandas (Ailuropoda melanoleuca) and ...

Gene expressions between obligate bamboo-eating pandas and non-herbivorous mammals reveal converged specialized bamboo diet adaptation

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 ...

Prevalence of the giant liver fluke (fascioloides magna, bassi, 1875) in red deer (cervus elaphus) in the region of floodplain forests of northern Serbia

Archives of Veterinary Medicine, 2018
This is the first study offering insights into the prevalence of giant liver fluke in the population of red deer in the territory of Serbia. Giang liver fluke (Fascioloides magna, Bassi, 1875) is the most important liver parasite among wild ruminants in ...

Multiple stellar populations in the Galactic globular cluster NGC 6752

, 2009
We have carried out high-precision photometry on a large number of archival HST images of the Galactic globular cluster NGC 6752, to search for signs of multiple stellar populations. We find a broadened main sequence, and demonstrate that this broadening

The red giant branch phase transition: Implications for the RGB luminosity function bump and detections of Li-rich red clump stars [PDF]

, 2015
We performed a detailed study of the evolution of the luminosity of He-ignition stage and of the red giant branch bump luminosity during the red giant branch phase transition for various metallicities.

Symbiotic Stars (Including T Corona Borealis) Are Not Immediate Progenitors of Normal Type Ia Supernovae

The Astrophysical Journal
A popular solution to the Type Ia supernova (SN Ia) progenitor problem is that the immediate progenitors are symbiotic star systems. This solution requires that the companion star of the exploding white dwarf must be a red giant star with a heavy stellar
