We show that collisions with stellar–mass black holes can partially explain the absence of bright giant stars in the Galactic Centre, first noted by Genzel et al. (1996). We show that the missing objects are low–mass giants and AGB stars in the range 1 − 3M⊙. Using detailed stellar evolution calculations, we find that to prevent these objects from evolving to become visible in the depleted K ba...

If I have seen further than others, it is by standing upon the shoulders of giants. If I have seen further than others, it is by standing upon the shoulders of giants.

Stars destroy lithium (Li) in their normal evolution. The convective envelopes of evolved red giants reach temperatures of millions of K, hot enough for the Li(p, α)He reaction to burn Li efficiently. Only about 1% of first-ascent red giants more luminous than the luminosity function bump in the red giant branch exhibit A(Li) > 1.5. Nonetheless, Li-rich red giants do exist. We present 15 Li-ric...

The properties of 322 intermediate-mass late-G giants (comprising 10 planet-host stars) selected as the targets of Okayama Planet Search Program, many of which are red-clump giants, were comprehensively investigated by establishing their various stellar parameters (atmospheric parameters including turbulent velocity fields, metallicity, luminosity, mass, age, projected rotational velocity, etc....

We consider BPS motion of dual giant gravitons on AdS5 × Y 5 where Y 5 represents a five-dimensional Sasaki-Einstein manifold. We find that the phase space for the BPS dual giant gravitons is symplectically isomorphic to the Calabi-Yau cone over Y 5, with the Kähler form identified with the symplectic form. The quantization of the dual giants therefore coincides with the Kähler quantization of ...

Context. This paper is a follow-up on the vast effort to collect radial velocity data for stars belonging to the Hipparcos survey. Aims. We aim at extending the orbital data available for binaries with M giant primaries. The data presented in this paper will be used in the companion papers of this series to (i) derive the binary frequency among M giants and compare it to that of K giants (Paper...

To date, the production of T-even bacteriophage with giant heads has been achieved in two ways: (i) by use of canavanine-arginine treatment of Escherichia coli B cultures infected by wild-type bacteriophage (Cummings and Bolin, Bacteriol. Rev. 40:314-359, 1976; Cummings et al., Virology 54:245-261, 1973), which give a size distribution of giants that is phage specific (Cummings et al., Virology...
