Accurate ages of stars (StellarAges)
Start date: Oct 1, 2013, End date: Sep 30, 2018,
Age is a fundamental property of stars. It is an essential tool to understand many diverse phenomena in astrophysics, including the evolution of stars, planetary systems, and the Galaxy. However, age is currently the most poorly known property of a star, often to no better than 30-40% accuracy, which is not good enough.The ages of stars cannot be measured directly; they can only be determined by c ...

High-Resolution Solar Physics Network (SOLARNET)
Start date: Apr 1, 2013, End date: Mar 31, 2017,
This project aims at integrating the major European infrastructures in the field of high-resolution solar physics. The following actions will be taken: (i) realise Trans-national Access to external European users; (ii) enhance and spread data acquisition and processing expertise to the Europe-wide community; (iii) increase the impact of high-resolution data by offering science-ready data and facil ...

From the Sun to stars - Interplay between dynamo and corona (DYNACOR)
Start date: Jan 1, 2015, End date: Dec 31, 2016,
Most stars show strong magnetic fields on their surfaces and sustain a hot outer atmosphere, the corona. Two of the fundamental problems in stellar astrophysics are how the stars generate their magnetic field, and how they manage to heat the corona to temperatures of two million K, well in excess of the surface. I will address these problems by performing local and global numerical simulations. Th ...

Understanding the variability of solar And STellar RAdiative fluxes (ASTRA)
Start date: Sep 15, 2014, End date: Sep 14, 2016,
The variable Sun is the primary external driver of natural climate change, as evidenced by positive correlations between solar variability and various climate indicators. Even though the Sun-Earth connection has been under close scrutiny over the last two decades, a number of crucial questions remain open. Thus, in the 4th IPCC assessment report the level of our understanding of the solar influenc ...

First European Comprehensive SOLar Irradiance Data exploitation (SOLID)
Start date: Dec 1, 2012, End date: Nov 30, 2015,
Variations of solar irradiance are the most important natural factor in the terrestrial climate and as such, the time dependent spectral solar irradiance is a crucial input to any climate modelling. There have been previous efforts to compile solar irradiance but it is still uncertain by how much the spectral and total solar irradiance changed on yearly, decadal and longer time scales. Observation ...
