On the serendipitous discovery of a Li-rich giant in the globular cluster NGC 362 [PDF]
, 2015 We have serendipitously identified the first lithium-rich giant star located close to the red giant branch bump in a globular cluster. Through intermediate-resolution FLAMES spectra we derived a lithium abundance of A(Li)=2.55 (assuming local ...

Oscillations in g-mode period spacings in red giants as a way to determine their state of evolution
EPJ Web of Conferences, 2015 In this work we consider the sensitivity of gravity-mode period spacings to sharp changes in the inner structure of red giant stars, more specifically in the buoyancy frequency inside the g-mode propagation cavity.

Infrared Spectroscopy of Symbiotic Stars. IV. V2116 Ophiuchi/GX 1+4, The Neutron Star Symbiotic [PDF]
, 2005 We have computed, based on 17 infrared radial velocities, the first set of orbital elements for the M giant in the symbiotic binary V2116 Ophiuchi. The giant's companion is a neutron star, the bright X-ray source GX 1+4. We find an orbital period of 1161

The brightness of the Red Giant Branch tip: Theoretical framework, a set of reference models, and predicted observables [PDF]
, 2017 The brightness of the tip of the Red Giant Branch is a useful reference quantity for several fields of astrophysics. An accurate theoretical prediction is needed for such purposes. Aims.

On the Correlation Between Metallicity and the X-Shaped Morphology of the Milky Way Bulge
, 2014 We demonstrate that failure to properly account for stellar evolution can bias results in determinations of the spatial morphology of Galactic bulge stars, focusing on the question of whether or not the X-shape is more pronounced among the more metal ...
