The PLATO 2.0 mission
PLATO 2.0 has recently been selected for ESA’s M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it addressesExpand

Asteroseismology of old open clusters with Kepler: direct estimate of the integrated red giant branch mass-loss in NGC 6791 and 6819
Mass-loss of red giant branch (RGB) stars is still poorly determined, despite its crucial role in the chemical enrichment of galaxies. Thanks to the recent detection of solar-like oscillations in G–KExpand

Serum and liver iron differently regulate the bone morphogenetic protein 6 (BMP6)‐SMAD signaling pathway in mice
The bone morphogenetic protein 6 (BMP6)‐SMAD signaling pathway is a central regulator of hepcidin expression and systemic iron balance. However, the molecular mechanisms by which iron is sensed toExpand

Gravity modes as a way to distinguish between hydrogen- and helium-burning red giant stars
Red giants are evolved stars that have exhausted the supply of hydrogen in their cores and instead burn hydrogen in a surrounding shell. Once a red giant is sufficiently evolved, the helium in theExpand

Predictions for Self-Pollution in Globular Cluster Stars
Fully evolutionary models have been built to follow the phases of asymptotic giant branch evolution with mass loss for metal mass fractions from Z = 2 ? 10-4 to Z = 4 ? 10-3. The hot bottom burningExpand

Bone morphogenetic protein signaling is impaired in an HFE knockout mouse model of hemochromatosis.
BACKGROUND AND AIMS Mutations in HFE are the most common cause of the iron-overload disorder hereditary hemochromatosis. Levels of the main iron regulatory hormone, hepcidin, are inappropriately lowExpand

The transition from carbon dust to silicate production in low-metallicity asymptotic giant branch and super-asymptotic giant branch stars
We compute the mass and composition of dust produced by stars with masses in the range and with a metallicity of Z= 0.001 during their asymptotic giant branch (AGB) and super-AGB phases. StellarExpand

A deep insight into the Mg–Al–Si nucleosynthesis in massive asymptotic giant branch and super-asymptotic giant branch stars
The stars in globular clusters are known to differ in their surface chemistry: spectroscopic investigations in recent decades outlined the presence of star-to-star differences in the abundances ofExpand

Dynamical masses of the low-mass stellar binary AB Doradus B
Context. AB Doradus is the main system of the AB Doradus moving group. It is a quadruple system formed by two widely separated binaries of pre-main-sequence (PMS) stars: AB Dor A/C and AB Dor Ba/Bb.Expand

The mass–metallicity relations for gas and stars in star-forming galaxies: strong outflow versus variable IMF
We investigate the mass-metallicity relations for the gaseous (MZRgas) and stellar components (MZRstar) of local star-forming galaxies based on a representative sample from SDSS DR12. TheExpand
