Nucleosynthesis in Red Giant Stars [PDF]
The production of elements from helium-3 to fluorine in low- and intermediate-mass stars is reviewed and compared to chemical abundances observed at the surface of both red giant branch and asymptotic giant branch stars. It is highlighted that, while the trends predicted by standard models are generally well confirmed, many chemical abundances observed

Red giant seismology: Observations
The CoRoT and Kepler missions provide us with thousands of red-giant light curves that allow a very precise asteroseismic study of these objects. Before CoRoT and Kepler, the red-giant oscillation patterns remained obscure.

Ensemble asteroseismology of red-giant stars
The successful launches of the CoRoT and Kepler space missions have led to the detections of solar-like oscillations in large samples of red-giant stars. The large numbers of red giants with observed oscillations make it possible to investigate the properties of the sample as a whole: ensemble asteroseismology.

Oscillations in g-mode period spacings in red giants as a way to determine their state of evolution
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.

IV.2 Pulsating red giant stars [PDF]
This book is dedicated to all the people interested in the CoRoT mission and the beautiful data that were delivered during its six year duration. Either amateurs, professional, young or senior researchers, they will find treasures not only at the time of this publication but also in the future twenty or thirty years. It presents the data in their final

Dynamical Substructures of Galactic Globular Clusters III. NGC 7006 [PDF]
To study the effects of giant population on dynamical substructures of the central region of NGC 7006, we examine the radial variations of ellipticity and position angle on BV stellar photometry using ellipse fitting technique.

Asteroseismology of Red Giant stars
Sun-like oscillations, that is p-modes excited stochastically by convective noise, have now been observed in a number of Red Giant stars. Compared to those seen in the Sun, these modes are of large amplitude and long period, making the oscillations attractive prospects for observation.

As the Kepler time series grew, so did the interest in the asteroseismology of very low-frequency solar-like oscillators. It is possible to accurately resolve modes for stars near the tip of the red giant branch.
