A sub-percent distance scale from binaries and Cepheids (CepBin)
Date du début: 1 nov. 2016, Date de fin: 31 oct. 2021,
We propose to carry out a project which will produce a decisive step towards improving the accuracy of the Hubble constant as determined from the Cepheid-SN Ia method to 1%, by using 28 extremely rare eclipsing binary systems in the LMC which offer the potential to determine their distances to 1%. To achieve this accuracy we will reduce the main error in the binary method by interferometric angula ...

Integrated Activities for the High Energy Astrophysics Domain (AHEAD)
Date du début: 1 sept. 2015, Date de fin: 28 févr. 2019,
We propose a set of integrated Activities in the High Energy Astrophysics Domain (AHEAD) in response to the INFRAIA-2014-2015 call Research Infrastructures for High EnergyAstrophysics.The overall objective of AHEAD is to integrate national efforts in high-energy Astrophysics and to promote the domain at the European level, to keep its community at the cutting edge of science and technology in this ...

Superfluid dynamics of neutron star crusts and cores (Super-DENSE)
Date du début: 1 août 2016, Date de fin: 31 juil. 2018,
Neutron stars are one of the most exciting nuclear physics laboratories in the Universe. With interior densities well above nuclear saturation density they allow us to probe conditions impossible to replicate on Earth. In addition the thermal energy of the star is negligible compared to the Fermi energy, and neutrons in the interior will be superfluid.Superfluidity affects the dynamics of the star ...

Probing Strong Gravity by Black Holes Across the Range of Masses (StrongGravity)
Date du début: 1 janv. 2013, Date de fin: 31 déc. 2017,
Black holes provide a crucial link between Einstein’s theory of gravity and real cosmic objects which astronomers can observe and study in the Universe. This project is oriented towards legacy of the cornerstone XMM-Newton X-ray satellite mission of European Space Agency (ESA) in synergy with relevant data in other spectral domains that are covered by ground-based infrared and radio interferometri ...

"Eclipsing binary stars as cutting edge laboratories for astrophysics of stellar structure, stellar evolution and planet formation" (BLAST)
Date du début: 1 déc. 2010, Date de fin: 30 nov. 2016,
"Spectroscopic binary stars (SB2s) and in particular spectroscopic eclipsing binaries are one of the most useful objects in astrophysics. Their photometric and spectroscopic observations allow one to determine basic parameters of stars and carry out a wide range of tests of stellar structure, evolution and dynamics. Perhaps somewhat surprisingly, they can also contribute to our understanding of th ...

Evolved stars: clues to the chemical evolution of galaxies (POSTAGBinGALAXIES)
Date du début: 1 avr. 2011, Date de fin: 31 mars 2015,
The late stages in the evolution of intermediate-mass stars (Asymptotic Giant Branch - AGB and post-AGB) are of the greatest importance for the chemical evolution of galaxies. Pulsations, dust formation, and mass loss through massive stellar winds are characteristic phenomena of AGB stars. Stellar pulsations cause waves, which travel into the outer layers of the atmosphere and develop shocks, comp ...

Realistic dense matter physics and numerical simulations of compact star spacetimes (DYNEOS2)
Date du début: 1 avr. 2008, Date de fin: 31 mars 2011,
"The ultimate goal of this project is to explore, by theoretical considerations and numerical calculations, the mysterious and presently at large unknown interiors of compact astrophysical objects. Comparison of theoretical results with observations will allow for putting constraints on the properties of extremely dense matter, which is not likely to be accomplished in Earth-based experiments in n ...
